Java.util.BitSet.clear() Method

Description

The java.util.BitSet.clear(int bitIndex) method sets the bit specified by the index to false.

Declaration

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

public void clear(int bitIndex)

Parameters

bitIndex − the index of the bit to be cleared.

Return Value

This method does not return a value.

Exception

IndexOutOfBoundsException − if the specified index is negative.

Example

The following example shows the usage of java.util.BitSet.clear() 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);

      // clear index 2 in bitset1
      bitset1.clear(2);

      // clear index 4 in bitset2
      bitset2.clear(4);

      // print new bitsets
      System.out.println("" + bitset1);
      System.out.println("" + bitset2);
   }
}

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