Advertisements


Description

The java.util.BitSet.intersects(BitSet set) method returns true if the specified BitSet has any bits set to true that are also set to true in this BitSet.

Declaration

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

public boolean intersects(BitSet set)

Parameters

  • set -- BitSet to intersect with

Return Value

This method returns boolean indicating whether this BitSet intersects the specified BitSet.

Exception

  • NA

Example

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

      // check if bitset1 intersects with bitset2
      System.out.println("" + bitset1.intersects(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}
true
