How to use Logical Operators in Java ?.


Logical Operators in Java -







Program to demonstrate working of Logical Operators in Java.


 
public class LogicalOperators {

 public static void main(String[] args) {

  // Logical AND Operator & , &&
  // F & F --> F
  // T & F --> F
  // F & T --> F
  // T & T --> T

  int number1 = 5;
  int number2 = 10;

  boolean b1, b2, b3, b4, b5, b6, b7;

  b1 = (number1 > 6) && (number2 > number1);
  System.out.println(b1);

  b2 = (number1 > 4) && (number2 > number1);
  System.out.println(b2);

  // Logical OR Operator | , ||
  // F | F --> F
  // T | F --> T
  // F | T --> T
  // T | T --> T

        b3 = (number1 > 6) || (number2 > 15);
        System.out.println(b3);
        
        b4 = (number1 > 3) || (number2 > 11);
        System.out.println(b4);

        // Logical NOT Operator !

        // !T ---> F
        // !F ---> T
        
        b5 = !(number1 > 3);
        System.out.println(b5);
        
        b5 = !(number1 > 6);
        System.out.println(b5);
        
        // Logical XOR Operator ^
        // F ^ F ---> F
        // T ^ F ---> T
        // F ^ T ---> T
        // T ^ T ---> F
        
        b6 = (number1 > 3) ^ (number2 > 6);
        System.out.println(b6);
        
        b6 = (number1 > 3) ^ (number2 > 11);
        System.out.println(b6);

 }

}
