Operators

Unary Operators


Common unary operators are:

    
+ : Indicates a positive value (typically not used as it's implied).
    
- : Negates a value, converting positive to negative or vice versa.
    
++ : Increments a value by 1 (both pre-increment and post-increment).
    
-- : Decrements a value by 1 (both pre-decrement and post-decrement).





Syntax Example:


    
num++;  // Post-increment, num becomes 6
    
++num;  // Pre-increment, num becomes 7
    
num--;  // Post-decrement, num becomes 6
    
--num;  // Pre-decrement, num becomes 5


Program

INPUT


public class UnaryOperatorsExample {
    public static void main(String[] args) {
        int num = 5;
        
        // Post-increment
        System.out.println("Post-increment (num++): " + (num++));  // Displays 5, then num becomes 6

        // Pre-increment
        System.out.println("Pre-increment (++num): " + (++num));  // num becomes 7, then displays 7

        // Post-decrement
        System.out.println("Post-decrement (num--): " + (num--));  // Displays 7, then num becomes 6

        // Pre-decrement
        System.out.println("Pre-decrement (--num): " + (--num));  // num becomes 5, then displays 5

    }
}
