Last Updated :

The hashCode() Method of BitSet class in Java is used to fetch the hash code value of a particular this BitSet. This returned hash codes value depends on the set bits of the bit set being passed.
Syntax:
BitSet.hashCode()
Parameters: The method does not accept any parameters.
Return Value: The method returns the hashcode value of the BitSet.
Below programs are used to illustrate the working of BitSet.hashCode() Method:
Program 1:
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
BitSet init_bitset = new BitSet();
init_bitset.set( 10 );
init_bitset.set( 20 );
init_bitset.set( 30 );
init_bitset.set( 40 );
init_bitset.set( 50 );
System.out.println( "BitSet: " + init_bitset);
System.out.println( "The HashCode: "
+ init_bitset.hashCode());
}
}
|
Output:
BitSet: {10, 20, 30, 40, 50}
The HashCode: 1075053010
Program 2:
import java.util.*;
public class BitSet_Demo {
public static void main(String args[])
{
BitSet init_bitset = new BitSet();
init_bitset.set( 40 );
init_bitset.set( 25 );
init_bitset.set( 31 );
init_bitset.set( 48 );
init_bitset.set( 53 );
System.out.println( "BitSet: " + init_bitset);
System.out.println( "The HashCode: "
+ init_bitset.hashCode());
}
}
|
Output:
BitSet: {25, 31, 40, 48, 53}
The HashCode: -2111765038
