One of the most commonly used conditional operators in Java is known as a ternary operator. In this blog post, we’ll discuss ternary operator in Java with examples. Ternary means having three components. To learn more about ternary operators, continue reading this blog post.
What is a Java ternary operator?
The ternary operator (? 🙂 has three operands. It is used to assess Boolean expressions. The operator will decide the value to assign to the variable. It is the only conditional operator that consists of three operands. You can use it in place of an if-else statement. It makes the code much more readable, easy, and shorter.
What is the syntax of the ternary operator in Java?
The following is the syntax of the ternary operator:
(condition) ? (return if true) : (return if false);
You often notice that the Java ternary operator consists of the following symboles: (? :).
How to use Java’s ternary operator?
To use the ternary operator in your code, follow the instructions given below:
- Give a condition in round brackets that will evaluate to true or false.
- After giving the condition in the round brackets, write a question mark
- After that, provide the value to show if the condition is true.
- Add a colon.
- Now, provide the value to show if the condition is false.
Java ternary operator with example
Check out the following program to understand how ternary operator in Java works:
import java.io.*;
class Ternary {
public static void main(String[] args)
{
int n1 = 6, n2 = 10, max;
System.out.println(“First num: ” + n1);
System.out.println(“Second num: ” + n2);
max = (n1 > n2) ? n1 : n2;
System.out.println(“Maximum is = ” + max);
}
}
The output will be:
First num: 6
Second num: 10
Maximum is = 10
In this example, the program declares class Ternary and assigns n1=6, n2=10. In this program, the ternary operator assesses if n1 is greater than n2. If the n1 is greater than n2, then the value of n1 will be shown. Otherwise, the value of n2 will be displayed.
When to use the ternary operator in Java?
In Java, you can use the ternary operator to replace if-else statements. For instance, you can replace the following code:
class Main {
public static void main(String[] args) {
int number = 20;
if(number > 0) {
System.out.println(“Positive Number”);
}
else {
System.out.println(“Negative Number”);
}
}
}
You can replace the above code with the following code using the Java ternary operator:
class Main {
public static void main(String[] args) {
int number = 20;
String result = (number > 0) ? “Positive Number” : “Negative Number”;
System.out.println(result);
}
}
Output: Positive Number
The output for both methods will remain the same. However, with the use of the ternary operator, the code becomes much more readable and easy to understand.
Which is better, the ternary operator or if-else in Java?
If you are dealing with short conditional expressions, then it is recommended to use a ternary operator. On the other hand, if you are using larger conditions, then you can use if-else statements. In simple words, the use of if-else or ternary operator will depend on the simplicity or complexity of conditions.
Can you have multiple conditions in a ternary operator?
Yes, you can use multiple conditions within a ternary operator by nesting the ternary operator. It creates a chain of multiple conditions the same as an if-else-if statement. It allows you to check multiple possibilities using a single expression. However, be careful while using nested ternary operators because they become complex to understand.
What are the advantages of ternary operators?
- The ternary operator allows you to write if-else statements in a simple and much more concise way, making the code easier to understand.
- Using the ternary operator in the right way can make the code easy to read and understand the purpose behind the code.
- It can be faster than an if-else statement.
- Java ternary operator can streamline complex logic by providing a concise way to perform conditional codes.
- If any issue arises in the code, the ternary operator can make it easy to address the reason behind the problem because it minimizes the complexity of the code that should be examined.
