Java Logical Operators

Java logical operators

Created By: chatGPT

In Java, logical operators are used to combine multiple Boolean expressions. These operators return a Boolean value: true or false. The three main logical operators are AND, OR, and NOT.

1. Logical AND (&&): This operator returns true only if both operands are true.

boolean a = true;
boolean b = false;
boolean result = a && b; // result will be false

2. Logical OR (||): This operator returns true if at least one of the operands is true.

boolean a = true;
boolean b = false;
boolean result = a || b; // result will be true

3. Logical NOT (!): This operator negates the value of the boolean expression. If the expression is true, it returns false, and vice versa.

boolean a = true;
boolean result = !a; // result will be false

You can also combine these operators to form more complex expressions. Parentheses can be used to control the order of evaluation.

boolean a = true;
b = false;
boolean result = (a && b) || (!a); // result will be true

Here is an example that demonstrates the use of logical operators in a conditional statement:

boolean isAdult = true;
boolean hasPermission = false;

if (isAdult || hasPermission) {
    System.out.println("Access granted.");
} else {
    System.out.println("Access denied.");
} // This will print 'Access granted.'
