Java Boolean logicalOr() Method

The logicalOr() method of Java Boolean class returns the result of implementing logical OR operation on the specified Boolean operands.

Syntax:

public static boolean logicalOr (boolean a, boolean b)

Parameters:

The parameters ‘a’ and ‘b’ represents first and second operands.

Return Value:

The logicalOr () method returns the result after implementing logical OR operation on the parameters a and b.

• It returns true, if either of the parameter is true.
• It returns false, if and only if both the parameters are false.

Example 1

public class JavaBooleanLogicalOrMethodExample1 {
    public static void main(String[] args) {
        Boolean b1 = true;
        Boolean b2 = false;
        // return boolean value after implementing logical OR operator
        Boolean b3 = Boolean.logicalOr(b1,b2);
        Boolean b4 = Boolean.logicalOr(b1,b1);
        Boolean b5 = Boolean.logicalOr(b2,b2);
        Boolean b6 = Boolean.logicalOr(b2,b1);
        System.out.println("1. "+b1+"  "+b2+" = "+b3);
        System.out.println("2. "+b1+"  "+b1+" = "+b4);
        System.out.println("3. "+b2+"  "+b2+" = "+b5);
        System.out.println("4. "+b2+"  "+b1+" = "+b6);
    }
}

Output

1.true false = true
2.true true = true
3.false false = false
4.false true = true

Example 2

import java.util.Scanner;
public class JavaBooleanLogicalOrMethodExample2 {
    public static void main(String[] args) {
        Boolean bool1 = true;
        Boolean bool2 = false;
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter the dividend : ");
        int dividend =scanner.nextInt();
        System.out.print("Enter the divisor : ");
        int divisor =scanner.nextInt();
        if(dividend<0 ||divisor<=0||divisor> dividend){
            bool1 = false;
        }
        Boolean bool3 =Boolean.logicalOr(bool1,bool2);
        if(bool3==true) {
            System.out.println("Quotient = "+dividend/divisor +"\nRemainder = "+dividend%divisor);
        }
        else{
            System.out.println("Plz enter a valid dividend and divisor.");
        }
    }
}

Output

Enter the dividend : 67
Enter the divisor : 0
Plz enter a valid dividend and divisor.

Example 3

import java.util.Scanner;
public class JavaBooleanLogicalOrMethodExample3 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int a, b;
        Boolean b1 = false;
        Boolean b2 = false;
        System.out.println("Enter two no.s");
        a = scanner.nextInt();
        b = scanner.nextInt();
        if (b>a){
            b1=true;
        }
        if (a == b) {
            System.out.println("Both are equal.");
        }
         else {
            boolean b3 = Boolean.logicalOr(b1, b2);
            if (b3 == true) {
                System.out.println(b + " is greater");
            }
            else {
                System.out.println(a + " is greater");
            }
         }
    }
}

Output

Enter two no.s
56
109
109 is greater
