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:
// Java code to illustrate HashCode() import java.util.*; public class BitSet_Demo { public static void main(String args[]) { // Creating an empty BitSet BitSet init_bitset = new BitSet(); // Use set() method to add elements into the Set init_bitset.set( 10 ); init_bitset.set( 20 ); init_bitset.set( 30 ); init_bitset.set( 40 ); init_bitset.set( 50 ); // Displaying the BitSet System.out.println( "BitSet: " + init_bitset); // Displaying the hashcode System.out.println( "The HashCode: " + init_bitset.hashCode()); } } |
BitSet: {10, 20, 30, 40, 50} The HashCode: 1075053010
Program 2:
// Java code to illustrate HashCode() import java.util.*; public class BitSet_Demo { public static void main(String args[]) { // Creating an empty BitSet BitSet init_bitset = new BitSet(); // Use set() method to add elements into the Set init_bitset.set( 40 ); init_bitset.set( 25 ); init_bitset.set( 31 ); init_bitset.set( 48 ); init_bitset.set( 53 ); // Displaying the BitSet System.out.println( "BitSet: " + init_bitset); // Displaying the hashcode System.out.println( "The HashCode: " + init_bitset.hashCode()); } } |
BitSet: {25, 31, 40, 48, 53} The HashCode: -2111765038
