Java Logical Operators

Java Logical Operators

Java Logical Operators are used to create boolean conditions, modify a boolean expression, or combine two or more simple conditions to form a complex condition.

Operator – Symbol – Example – Description

Java supports the following Logical Operators.

LogicalOperation	OperatorSymbol	Example	Description
AND	&&	a && b	Returns logical AND of a and b.
OR	||	a || b	Returns logical OR of a and b.
NOT	!	!a	Returns logical Not of a.

Tutorials

The following Java tutorials cover each of these Logical Operators in detail.

• Java – AND Operator
• Java – OR Operator
• Java – NOT Operator

Example

In the following example, we take two boolean values, and perform different Logical Operations on these values.

Main.java

public class Main {
    public static void main(String[] args) {
        boolean a = true;
        boolean b = false;
        
        boolean andResult = a && b;
        boolean orResult = a || b;
        boolean notResult = !a;

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

Output

a && b = false
a || b = true
!a     = false
