Java: Logical Operators

May 11, 2022

Operators

Java provides quite a variety of operators which come in handy to the programmer for the manipulation of variables.

The operators in java are as follows:

Arithmetic Operators
Relational Operators
Bitwise Operators
Logical Operators
Assignment Operators

Logical Operators

Logical operators are mainly used to control program flow. They allow a program to make a decision based on multiple conditions.

Operator	Functionality	Syntax
&&(Logical AND)	It returns true if both statements are true	a && b
\|\|(Logical OR)	It returns true if one of the statements is true	a \|\| b
!(Logical NOT)	It reverses the result, returns false if the result is true	!(a == b)

Syntax with Example

Run

public class Main {

   public static void main(String args[]) {
      boolean a = true;
      boolean b = false;

      System.out.println("a && b = " + (a&&b));
      System.out.println("a || b = " + (a||b) );
      System.out.println("!(a && b) = " + !(a && b));
   }
}

Output

a && b= false

a || b= true

!(a && b)= true
