Example:

In the example below, the java.util.BitSet.clear() method is used to clear the bit specified by the index in the given BitSet.

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("Before applying clear() method.");
    System.out.println("BSet contains: " + BSet);

    //using clear method to clear index 30
    BSet.clear(30);

    //printing BitSet
    System.out.println("\nAfter applying clear() method."); 
    System.out.println("BSet contains: " + BSet);   
  }
}

The output of the above code will be:

Before applying clear() method.
BSet contains: {10, 20, 30, 40, 50}

After applying clear() method.
BSet contains: {10, 20, 40, 50}
