Java Ternary Operator

August 4, 2023

Ternary Operator In Java?

The Java Ternary Operator is a shorthand way to write an if-else statement in a single line.

It takes three operands: a boolean expression, a value to be returned if the boolean expression is true, and a value to be returned if the boolean expression is false.

When to use the Ternary Operator?

The ternary operator should be used when you need to assign a value to a variable based on a single condition, and the value assigned to the variable is determined by the outcome of the condition.

It can be useful for simplifying code and reducing the number of lines needed for simple conditional assignments. It should not be used for complex conditions or multiple outcomes, as it can make the code harder to read and understand.

Nested Ternary Operators

Nested ternary operators refer to the usage of multiple ternary operators and are are multiple ternary operators nested within each other to handle complex conditions.

In a nested ternary operation, the second and third operands of a ternary operator can themselves be ternary operations.

Advantages of Java Ternary Operators

Easier debugging: Ternary operators are easier to debug because they are more concise and have fewer potential execution paths than if-else statements.

Promotes functional programming: Ternary operators are often used in functional programming to create more concise and expressive code.

Concise code: Ternary operators allow you to write conditional statements in a single line, making the code more concise and easier to read.

Avoiding repetitive code: Ternary operators allow you to avoid writing repetitive if-else statements, which can be tedious and error-prone.

Example 1: Java Program for ternary operator in Java

Run

public class Main {
    //TernaryOperatorExample
    public static void main(String[] args) {
        int num = -5;
        String result = (num > 0) ? "positive" : "negative";
        System.out.println("The number " + num + " is " + result);
    }
}

Output

The number -5 is negative

Explanation:

Create a variable num initialized to -5. We use the ternary operator to check if num is greater than 0. If it is, then we assign the string "positive" to the variable result. If it is not, then we assign the string "negative" to result.

Example 2: Java Nested Ternary Operator

Run

public class Main {
    //NestedTernaryOperatorExample
    public static void main(String[] args) {
        int num1 = 10;
        int num2 = 20;
        int num3 = 30;
        int max = (num1 > num2) ? ((num1 > num3) ? num1 : num3) : ((num2 > num3) ? num2 : num3);
        System.out.println("The maximum of " + num1 + ", " + num2 + " and " + num3 + " is " + max);
    }
}

Output

The maximum of 10, 20 and 30 is 30

Explanation:

we have three variables num1, num2 and num3 initialized to 10, 20 and 30 respectively. We use nested ternary operators to compare the three numbers and determine the maximum among them.

The outermost ternary operator checks if num1 is greater than num2. If it is, then the second ternary operator is evaluated, which checks if num1 is greater than num3. If it is, then num1 is the maximum number. If it is not, then num3 is the maximum number.

If num1 is not greater than num2, then the third ternary operator is evaluated, which checks if num2 is greater than num3. If it is, then num2 is the maximum number. If it is not, then num3 is the maximum number.
