Java.util.BitSet.length() Method

Description

The java.util.BitSet.length() method returns the "logical size" of this BitSet: the index of the highest set bit in the BitSet plus one. Returns zero if the BitSet contains no set bits.

Declaration

Following is the declaration for java.util.BitSet.length() method

public int length()

Parameters

• NA

Return Value

This method returns the logical size of this BitSet.

Exception

• NA

Example

The following example shows the usage of java.util.BitSet.length() method.

package com.tutorialspoint;

import java.util.*;

public class BitSetDemo {

   public static void main(String[] args) {

      // create 2 bitsets
      BitSet bitset1 = new BitSet(8);
      BitSet bitset2 = new BitSet(8);

      // assign values to bitset1
      bitset1.set(0);
      bitset1.set(1);
      bitset1.set(2);
      bitset1.set(3);
      bitset1.set(4);
      bitset1.set(5);

      // assign values to bitset2
      bitset2.set(2);
      bitset2.set(4);
      bitset2.set(6);
      bitset2.set(8);
      bitset2.set(10);

      // print the sets
      System.out.println("Bitset1:" + bitset1);
      System.out.println("Bitset2:" + bitset2);

      // print the length of each bitset
      System.out.println("" + bitset1.length());
      System.out.println("" + bitset2.length());
   }
}

Let us compile and run the above program, this will produce the following result:

Bitset1:{0, 1, 2, 3, 4, 5}
Bitset2:{2, 4, 6, 8, 10}
