BitSet length() Method in Java with Examples Last Updated : 27 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The length() Method of BitSet class in Java is used to know the logical size of this BitSet. This logical size is equal to the highest bit of the BitSet plus one. Syntax: BitSet.hashCode() Parameters: The method does not accept any parameters. Return Value: The method returns the logical size of the BitSet which is equal to the highest bit of the set plus one. The method returns zero if the BitSet is empty. Below programs are used to illustrate the working of BitSet.length() Method: Program 1: Java // Java code to illustrate length() 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(100); init_bitset.set(53); // Displaying the BitSet System.out.println("BitSet: " + init_bitset); // Displaying the length or logical size System.out.println("The Length is: " + init_bitset.length()); } } Output: BitSet: {25, 31, 40, 53, 100} The Length is: 101 Program 2: Java // Java code to illustrate length() import java.util.*; public class BitSet_Demo { public static void main(String args[]) { // Creating an empty BitSet BitSet init_bitset = new BitSet(); // Displaying the BitSet System.out.println("BitSet: " + init_bitset); // Displaying the hashcode System.out.println("The Length is: " + init_bitset.length()); } } Output: BitSet: {} The Length is: 0 Comment More infoAdvertise with us Next Article BitSet length() Method in Java with Examples chinmoy lenka Follow Improve Article Tags : Misc Java Java - util package Java-Functions Java-BitSet +1 More Practice Tags : JavaMisc Similar Reads BitSet size() Method in Java with Examples The size() Method of BitSet class in Java is used to know the size of this BitSet.
