Java BitSet | or()
  • Last Updated : 16 Aug, 2018

Prerequisite : Java BitSet | Set 1

BitSet is a class defined in the java.util package. It creates an array of bits represented by boolean values.
It performs a logical OR of the caller BitSet with the called BitSet. This BitSet gets set only when it is true and the BitSet argument has the value true.

Syntax:

public void and(BitSet set);

Examples:

Input : 
set1 : {1, 2, 4}
set2 : {2, 3, 4}

Output : After performing set1.or(set2)
set2 : {1, 2, 3, 4}

Program:






// Java program illustrating Bitset Class or() function.
import java.util.*;
public class GFG {
    public static void main(String[] args)
    {
        // Constructors of BitSet class
        BitSet set1 = new BitSet();
        BitSet set2 = new BitSet(6);
  
        /* set is BitSet class method
        expalined in next articles */
        set1.set(21);
        set1.set(45);
        set1.set(8);
        set1.set(23);
  
        // assign values to set2
        set2.set(12);
        set2.set(89);
        set2.set(21);
        set2.set(78);
        set2.set(93);
        set2.set(3);
  
        // Printing the 2 Bitsets
        System.out.println("set1 : " + set1);
        System.out.println("set2 : " + set2);
  
        // Performing logical AND
        // on set2 set with set1
        set2.or(set1);
  
        // set2 set after Performing AND
        System.out.println("After Performing OR :");
        System.out.println(set2);
    }
}
Output:
set1 : {8, 21, 23, 45}
set2 : {3, 12, 21, 78, 89, 93}
After Performing OR :
{3, 8, 12, 21, 23, 45, 78, 89, 93}
