What is BitSet or(BitSet set) in Java?
The void method or() is used to perform the logical OR operation. We can invoke this method with the dot (.) operator on invoking objects and performing the OR operation with the argument BitSet bitset object. The result of an OR operation will be returned through invoking an object, i.e., bitset1.or(bitset2).
This built-in BitSet class implements a vector of bits, available at
java.util.*.
Syntax
public void or(BitSet set)
Parameters
set: The method accepts objects of BitSet type.
Return value
The method does not return any object.
Example
In the code snippet below, we use the java.util.Random and java.util.BitSet classes to generate random numbers and bitset objects, respectively. Therefore, we have two objects (bitset1, bitset2) of the BitSet class. In line 20, we apply an OR logical operation and store the resultant value in invoking object bitset1.
import java.util.BitSet;// Random Class for random number generatorimport java.util.Random;class EdPresso {public static void main( String args[] ) {// object for Random ClassRandom rand = new Random();// objects of BitSet ClassBitSet bitset1 = new BitSet(20);BitSet bitset2 = new BitSet(20);// set some bitsfor(int i = 0; i < 10; i++) {bitset1.set(rand.nextInt(30));bitset2.set(rand.nextInt(30));}System.out.println("bitset1: ");System.out.println(bitset1);System.out.println("\nbitset2: ");System.out.println(bitset2);// OR bitsbitset1.or(bitset2);System.out.println("\nbitset1 OR bitset2: ");System.out.println(bitset1);}}
