# Java Relational and Logical Operators

### Relational Operators in Java :

Relational operators are used to evaluate conditions (true or false) inside the if statements. Some examples of relational operators are:

• == (equals)

• >= (greater than or equals to)

• > (greater than)

• < (less than)

• <= (less than or equals to)

• != (not equals)

• Note: ‘=’ is used for an assignment whereas ‘==’ is used for equality check. The condition can be either true or false.

### Logical Operators :

Logical operators are used to provide logic to our Java programs.
There are three types of logical operators in Java :
• && - AND

• || - OR

• ! – NOT

• ### AND Operator :

Evaluates to true if both the conditions are true.

• Y && Y = Y

• Y && N = N

• N && Y = N

• N && N = N

• Convention: # Y – True and N - False

• ### OR Operator :

Evaluates to true when at least one of the conditions is true.

• Y || Y = Y

• Y || N = Y

• N || Y = Y

• N || N = N

• Convention: # Y – True and N - False

• ### NOT Operator :

Negates the given logic (true becomes false and vice-versa)

• !Y = N

• !N = Y

• ### Example

``````package com.company;

public class logical {
public static void main(String[] args) {
System.out.println("For Logical AND...");
boolean a = true;
boolean b = false;
if (a && b){
System.out.println("Y");
}
else{
System.out.println("N");
}

System.out.println("For Logical OR...");

if (a || b){
System.out.println("Y");
}
else{
System.out.println("N");
}

System.out.println("For Logical NOT");
System.out.print("Not(a) is ");
System.out.println(!a);
System.out.print("Not(b) is ");
System.out.println(!b);
}
}
``````

### Output

For Logical AND...
N
For Logical OR...
Y
For Logical NOT
Not(a) is false
Not(b) is true
