Parameters

Return Value

Returns the value of the bit with the specified index.

Example:

In the example below, the java.util.BitSet.get() method is used to check the bit value with the specified index is present in the given BitSet or not.

import java.util.*;

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

    //populating BitSet
    BSet.set(2);
    BSet.set(4);
    BSet.set(6);
    BSet.set(8);
    BSet.set(10);

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

    //check the presence of bit value with
    //specified index in the given BitSet
    System.out.println(BSet.get(5));
    System.out.println(BSet.get(6));
  }
}

The output of the above code will be:

BSet contains: {2, 4, 6, 8, 10}
false
true
