BigInteger Class or() method

• or() method is available in java.math package.
• or() method is used to perform OR operation between the value of this BigInteger and the value of the given BigInteger.
• or() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• or() method does not throw an exception at the time of performing OR operation.

Syntax:

    public BigInteger or(BigInteger val);

Parameter(s):

• BigInteger val represents the object by which to perform OR with this BigInteger.

Return value:

The return type of this method is BigInteger, it returns BigInteger that holds the value [(this BigInteger) or (BigInteger val)].

Example:

// Java program to demonstrate the example 
// of BigInteger or(BigInteger val) method of BigInteger

import java.math.*;

public class OrOfBI {
    public static void main(String args[]) {
        // Initialize two variables str1 and str2
        String str1 = "10";
        String str2 = "4";

        // Initialize two BigInteger objects 
        BigInteger b_int1 = new BigInteger(str1);
        BigInteger b_int2 = new BigInteger(str2);

        System.out.println("b_int1: " + b_int1);
        System.out.println("b_int2: " + b_int2);

        // performs logical or (|) operation between 
        // this BigInteger b_int1 and the given BigInteger
        // b_int2 like 10 | 4 so the binary representation 
        // of 10 is 1010 and for 4 is 0100 so when we perform
        // (|) operation between bits it sets 1 when any of the bits
        // value is 1 otherwise it sets 0 so the result is
        // (1010 | 0100 = 1110)
        BigInteger or_val = b_int1.or(b_int2);
        System.out.println("b_int1.or(b_int2): " + or_val);
    }
}

Output

b_int1: 10
b_int2: 4
b_int1.or(b_int2): 14
