Below programs illustrate the java.util.GregorianCalendar.hashCode() function:
Program 1:
import java.io.*;
import java.util.*;
class GFG {
public static void main(String[] args) {
GregorianCalendar c = (GregorianCalendar)
GregorianCalendar.getInstance();
System.out.println( "Current Date and Time : "
+ c.getTime());
System.out.println( "Hash Code:" + c.hashCode());
}
}

Output:
Current Date and Time : Fri Jul 27 11:43:16 UTC 2018
Hash Code:-612105832
Program 2:
import java.io.*;
import java.util.*;
class GFG {
public static void main(String[] args) {
GregorianCalendar c = (GregorianCalendar)
GregorianCalendar.getInstance();
System.out.println( "Current Date and Time : "
+ c.getTime());
c.add((GregorianCalendar.YEAR), - 12 );
System.out.println( "Modified Date and Time : "
+ c.getTime());
System.out.println( "Hash Code of the " +
"modified date and time:" + c.hashCode());
}
}
