Java.util.BitSet.set() Method

Description

The java.util.BitSet.set(int bitIndex,boolean value) method sets the bit at the specified index to the specified value.

Declaration

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

public void set(int bitIndex,boolean value)

Parameters

• bitIndex − a bit index.

• value − a boolean value to set.

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.set() 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);

      // set more values
      bitset1.set(1, false);
      bitset1.set(5, true);
      bitset1.set(10, true);
      bitset2.set(1, false);
      bitset2.set(5, true);
      bitset2.set(10, true);

      // print the sets
      System.out.println("Bitset1:" + bitset1);
      System.out.println("Bitset2:" + 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}
Bitset1:{0, 2, 3, 4, 5, 10}
Bitset2:{2, 4, 5, 6, 8, 10}
