BitSet hashCode Method in Java with Examples Last Updated : 27 Dec, 2018 Summarize Comments Improve Suggest changes Share Like Article Like Report 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 // 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 // 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 Comment More infoAdvertise with us Next Article Byte hashCode() method in Java with examples C chinmoy lenka Follow Improve Article Tags : Misc Java Java - util package Java-Functions Java-BitSet +1 More Practice Tags : JavaMisc Similar Reads Byte hashCode() method in Java with examples The hashCode() method of Byte class is a built in method in Java which is used to return the hash code of the ByteObject.
