Java Boolean logicalAnd() Method

The logicalAnd() method of Java Boolean class returns the result of implementing logical AND operation on the assigned Boolean operands.

Syntax:

Parameters:

The parameters passed are a ( first Boolean operand) and b (second Boolean operand).

Return Value:

The logicalAnd() method returns the result of applying logical AND operation on Boolean parameters a and b.

Example 1

public class BooleanLogicalAndExample1 {
    public static void main(String[] args) {

        Boolean b1 = true;
        Boolean b2 = true;
        // when bool values are true logicalAnd() method returns true
        Boolean b3 = Boolean.logicalAnd(b1,b2);
        System.out.println("1. logicalAnd() method for "+b1+" "+b2+" is "+b3);
        Boolean b4 = true;
        Boolean b5 = false;
        // if either of the bool value if false logicalAnd() method returns false.
        Boolean b6 = Boolean.logicalAnd(b4,b5);
        System.out.println("2. logicalAnd() method for "+b4+" "+b5+" is "+b6);

    }
}

Test it Now

Output:

1. logicalAnd() method for true true is true
2. logicalAnd() method for true false is false

Example 2

import java.util.Scanner;

public class BooleanLogicalAndExample2 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your percentage.");
        Double d1 = scanner.nextDouble();
        Boolean b1 = true;
        Boolean b2 = false;
        if (d1 > 64) {
            b2 = true;
            // logicalAnd() method will return true bool value
            Boolean b3 = Boolean.logicalAnd(b1,b2);
            if((b3==true)) {
                System.out.println("Congratulation! You have passed.");
            }
        }
        else{
            double d2=64.0-d1;
            System.out.println("Sorry! You have failed. You needed "+d2+" more marks to pass.\nTry again next year.");
        }
    }
}

Output:

Enter your percentage.
63
Sorry! You have failed. You needed 1.0 more marks to pass.
Try again next year.

Example 3

import java.util.Scanner;

public class BooleanLogicalAndExample3 {
    public static void main(String[] args) {
                Scanner scanner = new Scanner(System.in);
                System.out.println("Enter two number.");
                int a[] = new int[3];
                for (int i = 0; i < 2; i++) {
                    a[i] = scanner.nextInt();
                }
                Boolean b1 = true;
                Boolean b2 = false;
                int val=0;
                int rem=0;
                for (int i = 0; i < 2; i++) {
                    if (a[1] == 0) {
                        b2 = true;
                        break;
                    }
                    else{
                        val = a[i]/a[i+1];
                        rem= a[i]%a[i+1];
                        break;
                    }
                }
                //logicalAnd() method will give same result as equals() method
                if (Boolean.logicalAnd(b1,b2)) {
                    System.out.println("Divide = "+a[0]+"/"+a[1]+"\nDivision is not possible.");
                } else {
                    System.out.println("Divide = "+a[0]+"/"+a[1]+"\nAfter division.\nQuotient = "+val +"\nRemainder = "+rem);
                }
            }
        }

Output:

Enter two number.
0
0
Divide = 0/0
Division is not possible.
