In Java, the Conditional Operator is a ternary operator that provides a concise way to write simple if-else statements. It is called a ternary operator because it takes three operands. The conditional operator is represented by the symbol ? :.

Syntax

variable = (condition) ? expression1 : expression2;

Condition: It is a Boolean expression that evaluates to either true or false.
Expression1: Executed if the condition is true.
Expression2: Executed if the condition is false.

Example 1: Using Conditional Operator

public class Main {
    public static void main(String[] args) {
        int a = 10, b = 20;
        
        // Using conditional operator to find the larger number
        int max = (a > b) ? a : b;
        
        System.out.println("The larger number is: " + max);
    }
}

Output:

The larger number is: 20

Example 2: Using Conditional Operator for Even or Odd

public class Main {
    public static void main(String[] args) {
        int num = 7;
        
        // Check if the number is even or odd using the conditional operator
        String result = (num % 2 == 0) ? "Even" : "Odd";
        
        System.out.println("The number is: " + result);
    }
}

Output:

The number is: Odd

When to Use Conditional Operator

It is best used for simple conditions and assignments.
It makes code more readable and compact compared to using traditional if-else statements.
Avoid using it for complex conditions as it may reduce readability.

You can now have an idea that the conditional operator reduces the lines of code, and make our task easier.
