Java.util.BitSet.set() Method

Description

The java.util.BitSet.set(int fromIndex,int toIndex,boolean value) method sets the bits from the specified fromIndex (inclusive) to the specified toIndex (exclusive) to the specified value.

Declaration

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

public void set(int fromIndex,int toIndex,boolean value)

Parameters

• fromIndex − index of the first bit to be set.

• toIndex − index after the last bit to be set.

• value − value to set the selected bits to

Return Value

This method does not return a value.

Exception

IndexOutOfBoundsException − if fromIndex is negative, or toIndex is negative, or fromIndex is larger than toIndex.

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, 10, false);
      bitset2.set(5, 15, 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}
Bitset2:{2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}
