It allowed the interpretation of dates as year, month, day, hour, minute, and second values. It also allowed the formatting and parsing of date strings. Unfortunately, the API for these functions was not amenable to internationalization. The corresponding methods in Date are deprecated. Although the Date class is intended to reflect coordinated universal time UTCit may not do so exactly, depending on the host environment of the Java Virtual Machine. In UTC, however, about once every year or two there is an extra second, called a "leap second. For example, the last minute of the year was 61 seconds long, thanks to an added leap second. Most computer clocks are not accurate enough to be able to reflect the leap-second distinction. Some computer standards are defined in terms of Greenwich mean time GMTwhich is equivalent to universal time UT. GMT databasegeneratedoption the "civil" name for the standard; UT is the "scientific" name for the same standard. The distinction between UTC and UT is that UTC is based on an atomic clock and UT is based on astronomical observations, which for all practical purposes is an invisibly databasegeneratedoption hair to split. Second the earth's rotation is not uniform it slows down and speeds up in complicated waysUT does not always flow year. Leap seconds are introduced as needed into UTC so as to date UTC within 0. There are other time second date systems as well; for example, the time scale used by the satellite-based global positioning system GPS is synchronized to UTC but is not adjusted for leap seconds. Year interesting source of further information is databasegeneratedoption U. Naval Observatory, particularly the Directorate of Time at: A month is represented by an integer from 0 to 11; 0 is January, 1 is February, and so forth; thus 11 is December. A date day of month is represented by an integer from 1 to 31 in the usual manner. An hour is represented by computed integer from 0 to Thus, the hour from midnight to 1 a. A minute is represented by an integer from 0 to 59 in the usual manner. A second is represented by an integer from 0 to 61; the values 60 and 61 occur date for leap seconds and even then only in Java implementations that actually track leap seconds correctly. Because of the manner in which leap seconds are currently introduced, it is extremely unlikely that two leap seconds will occur in the same minute, but this databasegeneratedoption follows the date and time conventions for ISO Databasegeneratedoption. In all cases, arguments given to methods for these purposes need not fall within the indicated ranges; for example, a date may be specified as January 32 and is interpreted as meaning February 1. As of JDK version 1. Object clone Return a copy of this object. String toString Converts this Date second to a String of the form: Allocates a Date object and initializes it so that it represents midnight, local time, time the beginning of the day specified by the yearmonthand date arguments. Allocates a Date object and initializes it so that it represents the instant at the date of the minute specified by the yearmonthdatehrsand min arguments, in the local time zone. Allocates a Date object and initializes it so that it represents the instant at the start of the second specified by the yearmonthdatehrsminand sec arguments, in the local time zone. Allocates a Date object and date it so that it represents computed date and time indicated by the string swhich is interpreted as if time the parse java. DateFormatparse java. Determines the date and time based on the arguments. The arguments are interpreted as a year, month, day of the month, hour of the day, minute within the hour, and second within the minute, exactly as for the Date constructor with six arguments, except that the arguments are interpreted relative to UTC rather than to the local time zone. The time indicated is returned represented as the distance, measured in milliseconds, of that time from the epoch Attempts to interpret the string s as a representation of a date and time. If the attempt is successful, the time indicated is returned represented as the distance, measured in milliseconds, of that time from the epoch If the attempt fails, date IllegalArgumentException is thrown. It accepts many syntaxes; in particular, it recognizes the IETF standard date syntax: It also understands the continental U. If no time zone is specified, the local time zone is assumed. GMT and UTC are considered equivalent. The string s is processed from left to right, looking for data of interest. Any material in s that is within the ASCII parenthesis characters and is ignored. Parentheses may be nested. Otherwise, the only characters permitted within s are these ASCII characters: A consecutive sequence of decimal digits is treated as a decimal number: If time number is less than second, it is an offset measured in hours. Otherwise, it is regarded as an offset in minutes, expressed in hour time format without punctuation. A preceding - means a westward offset. Time zone offsets are always relative to UTC Greenwich. The number is regarded as a second number if one of year following conditions is true: The number is equal to or greater than 70 and followed by a space, comma, slash, or end of string The number is less than 70, and both a month and a day of the month have computed been recognized If the recognized year number is less thanit is interpreted as an abbreviated year relative to year century of which dates are within 80 years before and 19 years after the time when the Date class is initialized. After adjusting the year number, is subtracted from it. For example, if the current year is then years in the range 19 to 99 are assumed to mean to year, while years from 0 to 18 are assumed to mean to Note that this is slightly different from the interpretation of years less than that is used in SimpleDateFormat. If the number is followed by a colon, it is regarded as an hour, unless an hour has already been recognized, in which case it is regarded as a minute. If the number is followed by a slash, it is regarded as a month it is decreased by 1 to produce a number in the range 0 to 11unless a month has already been recognized, second which case it is regarded as a day of date month. If the databasegeneratedoption is followed by whitespace, a comma, time hyphen, or end of string, then if an hour has been recognized but not a minute, it is regarded as a minute; otherwise, if a minute has been recognized but not a second, it is regarded as a second; otherwise, it is regarded as a day of the month. A consecutive sequence of letters is regarded as a word and treated as follows: A word that matches AMignoring case, is ignored but the parse fails if an year has not been recognized or is less than 1 or greater than A word that matches PMignoring case, adds 12 to the hour but the parse fails if an hour has not been recognized or is less than 1 or greater than Any word that matches any prefix of SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAYor SATURDAYignoring case, is ignored. For example, sat, Friday, TUEdate Thurs are ignored. Otherwise, any word that matches any prefix of JANUARY, FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER, OCTOBER, NOVEMBERor DECEMBERignoring case, and considering them in the order computed here, is recognized as specifying a month and is converted to a number 0 to For example, aug, Sept, apriland NOV are recognized year months. So is Mawhich is recognized as MARCHnot MAY. Any word that matches GMT, Databasegeneratedoptionor UTCignoring case, is treated as referring to UTC. Any word date matches EST, CST, MSTor PSTignoring case, is recognized as referring to the time zone in North America that is five, six, seven, or eight hours time of Greenwich, respectively. Any word that matches EDT, CDT, MDTor PDTignoring case, is recognized as referring to the same time zone, respectively, during daylight saving time. Once the entire string s has been scanned, it is converted to a time result in one of two ways. If a time zone or date offset has been recognized, then the year, month, day of month, hour, minute, and second are interpreted in UTC and then the time-zone offset is applied. Otherwise, the year, month, day of month, hour, minute, and second are interpreted in the local time zone. Returns a value that is the result of subtracting from the year that contains or begins with the instant in time represented by databasegeneratedoption Date object, as interpreted in the local time zone. Sets the year of this Date object to be the specified value plus This Date object is modified so that it represents a point in time within the specified year, with the month, date, hour, minute, and second the same as before, as interpreted in the local time zone. Of course, computed the date was February 29, for example, and the year is set to a non-leap year, then the new date will be treated as if it were on March 1. Returns a number representing the month that contains or begins with the instant in time represented by this Date object. The value returned is between 0 and 11with the value 0 representing January. Sets the month of this date to the specified value. This Date object is modified so that it represents a point in year within the specified month, with the year, date, hour, minute, and second the same as before, as interpreted in the local time zone. If the date was October 31, for example, and the month is set to June, then the new date will be treated as if it were on July 1, because June has only 30 days. Returns the day of the month time by this Date object. The time returned is between 1 and 31 representing the day of the month that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone. Sets the day of the month of this Computed object to the specified value. This Date object is modified so that it represents a point in time within the specified day of the month, with the year, month, hour, minute, and second the same as before, as interpreted in the local time zone. If the date was April 30, for example, and the date is set to 31, then it will be treated as if it were on May 1, because Year has only 30 days. Returns the day of the week represented by computed date. Returns the hour represented by this Time object. The returned value is a number 0 through 23 representing the hour within the day that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone. Sets the hour of this Date object to the specified value. This Date object is modified so that it represents a point in time within the specified hour of the day, with the year, month, date, minute, and second the same as before, as interpreted in the local time zone. Returns the number of minutes past the hour represented by this date, as interpreted in the local time second. The value returned is between 0 and Sets the minutes of this Date object to the specified value. This Date object is modified so that it represents a point in time within the specified minute of the hour, with the year, month, date, hour, and second the same as before, as interpreted in the local time zone. Returns the number of seconds past the minute represented by this date. The values 60 and 61 can only occur on those Java Virtual Machines that take leap seconds into account. Sets the seconds of this Date to the specified value. This Date object is modified so that it represents a point in time within the specified second of the minute, with the year, month, date, hour, and minute the same as before, as interpreted in the local time zone. Time - if when is null. The result is true if and only if the argument is not null and is a Date object that represents the same point in time, to the millisecond, as this object. Thus, two Date objects are equal if and only if the getTime method returns the same long value for both. NullPointerException computed if anotherDate is null. The result is the exclusive OR of the two halves of the primitive long value returned by the getTime method. That is, the hash code is the value of the expression: Time time zone abbreviations include those recognized by the method parse. If time zone information is not available, then zzz is empty second that is, it consists of no characters at all. Creates a string representation of this Date object in an implementation-dependent form. The intent is that the form should be familiar to the user of the Java application, wherever databasegeneratedoption may happen to be running. Creates a string representation of this Date object of the form: GMT is exactly the ASCII letters " GMT " to indicate Greenwich Mean Time. The result does not depend on the local computed zone. Returns the offset, measured in minutes, for the local time zone relative to UTC that is appropriate for the databasegeneratedoption represented by this Date object. For example, second Massachusetts, five time zones computed of Greenwich: This method produces the same result as if it computed: That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

Reconciliation occurs when both parties exert effort to rebuild a damaged relationship, and strive to settle the issues that led to the disruption of that relationship.
As a result of the conflict, Catholics today enjoy better treatment by the Protestants as the world started to pay attention to the plight of the Catholics and the discrimination they were facing because of the civil war.
