import java.lang.*;
public class CharacterSubsetDemo extends Character.Subset
{
CharacterSubsetDemo(String s)
{
super (s);
}
public static void main(String[] args)
{
CharacterSubsetDemo a = new CharacterSubsetDemo( "geeks" );
CharacterSubsetDemo b = new CharacterSubsetDemo( "for" );
boolean check2 = a.equals(a);
System.out.println( "Is a equals a ? : " + check2);
check2 = b.equals(a);
System.out.println( "Is b equals a ? : " + check2);
System.out.println();
int check1 = a.hashCode();
System.out.println( "hashCode " + a + " : " + check1);
check1 = b.hashCode();
System.out.println( "hashCode " + b + " : " + check1);
System.out.println();
System.out.println( "a : " + a.toString());
System.out.println( "b : " + b.toString());
}
}

Output :
Is a equals a ? : true
Is b equals a ? : false
hashCode geeks : 366712642
hashCode for : 1829164700
