The Java ternary operator allows you to write an if statement on a line of code. A ternary operator can return true or false. Returns a specified value depending on whether the statement is true or false.
We use Java if ... else instructions to control the flow of ’a program. An if statement will evaluate whether an expression is true or false. This declaration executes a specific block of code if the expression equals true.
However, if ... else statements on multiple lines. If you are evaluating a basic expression , your syntax may get unnecessarily verbose. This is where the ternary operator comes in. The Java ternary operator is used to simply replace if ... else statements to make the code easier to read.
This tutorial will discuss how to use the Java ternary operator. We will look at an example so that you can learn how to use this operator. Let’s get started!
Java ternary operator
The Java ternary operator allows you to write concise if ... else statements. Ternary statements get their name because they accept three conditions. A ternary operator evaluates whether a statement is true or false and returns a value determined according to the result of the operator
Here is the syntax for a ternary operator in Java:.
The origin of the name "ternary" refers to the way a ternary operator has three parts. Our declaration accepts three operands: the value assigned to variable if the expression is true
expressionIsFalse is the value assigned to variable if the expression is false It does The content of the ternary operator must not be assigned to a variable. For example, you can write a ternary operator in a System.out.println () release. see the result of your ternary operator in the java console
Unlike an "if" , the ternary operator does not accept "other" word - key statement . The ternary declaration uses a colon (:) to represent an "other" condition.
Let use an example to show this operator in action.
Java example of a ternary operator
Suppose you are creating a commercial website. We want people to be able to buy products only if they are 16 years of age or older.
To verify the age of our customers, we can use a ternary operator. This is more effective than using an "if" statement because a user cannot be under 16 or over 16. Here is an example of a program that would do the job of checking the age of a user:
Our code evaluates our ternary. Our condition is true, our code returns:.
All of first, we’ll define a class called EvaluateAge. Next, we declare a variable Java called age. This variable stores the age value of our client. age is assigned the value 22.
We declare a variable called "Result‚" whose value is equal to the result of our ternary operator. The ternary operator evaluates whether the "age" is equal to or greater than 16 ("age> = 16 ").
If the expression returns true , operator comes back "This user is over 16 years old. Otherwise, the operator returns This user is under 16. In the last line of our code, we print the message returned by the Result variable.
If our user’s age was 15, our code would be the following result of Java string:
indeed, our ternary evaluates false if the user’s age is not equal to or greater than 16 years. We have successfully created a system to check if a user is old enough to use our services.
When to use ternary Java operators
Termaru operators should be used if you have a simple "if" statement that you want to appear more concise and in your code . The ternary operator makes your code more readable.
In our example above, we evaluated the expression. If we wrote the code to assess the age of our user as "if" statement, we would write:
if is simple, but spanned five lines. Using a ternary declaration, we’ve reduced our if to a single line.
In general, you should only use ternary statements when the resulting statement is short. Otherwise, write a normal if statement. The purpose of a ternary operator is to make the code more concise and easier to read. Moving to a complex if statement in a ternary operator goes to the counter to this goal
Both operators Java ternary and conditional operators of the if statement evaluate Boolean expressions. Boolean expressions are those where the only output can be true or false. To learn more about Java Booleans, see our complete guide Java Booleans .
Conclusion
The ternary operator is a feature in Java that allows you to write more concise si statements to control the flow of code. These operators are called ternary because they accept three operands.
In this tutorial, we have covered the basics of Java ternary operators. He also explored how ternary operators deal with Java if statements, as well as examples of each in action.
