BitSet hashCode Method in Java with Examples
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()); }} |
Output:
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()); }} |
Output:
BitSet: {25, 31, 40, 48, 53}
The HashCode: -2111765038
