`value`	Specify a boolean value to set.

Return Value

void type.

Exception

Throws IndexOutOfBoundsException, if the specified index is negative.

Example:

In the example below, the java.util.BitSet.set() method is used to assign values in the given BitSet by setting the bit at the specified index to specified value.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {   
    //creating a BitSet
    BitSet BSet = new BitSet();

    //populating BitSet
    BSet.set(10);
    BSet.set(20);
    BSet.set(30);
    BSet.set(40);
    BSet.set(50);

    //printing BitSet
    System.out.println("BSet contains: " + BSet);

    //setting more values using set method
    BSet.set(40, false);
    BSet.set(50, false); 
    BSet.set(45, true);
    BSet.set(55, true);       

    //printing BitSet
    System.out.println("BSet contains: " + BSet);
  }
}

The output of the above code will be:

BSet contains: {10, 20, 30, 40, 50}
BSet contains: {10, 20, 30, 45, 55}
