Java.util.BitSet.get() Method

Description

The java.util.BitSet.get(int bitIndex) method returns the value of the bit with the specified index. The value is true if the bit with the index bitIndex is currently set in this BitSet; otherwise, the result is false.

Declaration

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

public boolean get(int bitIndex)

Parameters

• bitIndex -- the bit index.

Return Value

This method returns the value of the bit with the specified index.

Exception

• IndexOutOfBoundsException -- if the specified index is negative.

Example

The following example shows the usage of java.util.BitSet.get() 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);

      // get index 4 of bitset1
      System.out.println("" + bitset1.get(4));

      // get index 30 of bitset2
      System.out.println("" + bitset2.get(30));

   }
}

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}
true
false
