conditional operator in java  

Conditional operators are operators that check for a condition and return one value or another, depending on whether the condition is met.

Conditional operators are also known as “ternary” operators because they have three operands instead of the usual two. This article explains conditional operator in Java and details about &&, || and ?: operators in Java. Read on to learn more.

If you’re coming to conditional operators from another programming language, you might not find anything particularly unusual about them – they’re just like most other ternary operators in other languages.

But if this is your first time encountering these types of operators, it’s worth reading through this article to get familiarized with them and understand how to use them effectively in your code.

Conditional operator in Java

The conditional operator in Java (? 🙂 is a ternary operator that allows us to join two (or more) conditions together and have the program execute one statement if the first condition is true and another if the first condition is false.

The first condition is followed by an “if” and the second condition is followed by an “else”. All conditional operators work on boolean expressions.

The first condition is followed by an “if” and the second condition is followed by an “else”. All conditional operators work on boolean expressions.

What is Conditional Operator in Java?

The ternary operator consists of three operands, one conditional expression and one result. The conditional expression is evaluated and then the ternary operator is used to determine which result is returned.

Here are a few examples of how a conditional operator might be used. The following code checks to see if the user is logged in. If they are, it displays their name and if they aren’t, it displays a message telling them to log in.

userName = userLoggedIn() ? userName : “Login” The following code displays a user’s name, their age and a different message, depending on what they’ve selected in a dropdown menu. displayUserInfo( userSelected(), userAge() ? age : “Select”, userMessage() ? “option” : “message”)

Ternary Operator ? : in Java

The question mark operator, also called the “conditional operator”, evaluates a boolean expression and then returns the value of the expression’s if clause if it is true, and the value of its else clause if it is false.

The general form of this operator is: Boolean expression (“condition”) if true else expression (“else if false”) A simple example: int x = 0; x = x > 0 ? x : 10 This code snippet sets the value of x to 10 if it is less than 0, or to 0 if it is more than 0. Remember, a non-zero value is false and a zero value is true.

Ternary Operator && in Java

The logical AND operator is a binary operator that evaluates a boolean expression and then returns the value of the second expression if and only if the first expression is false.

The general form of this operator is: Boolean expression (“condition”) first expression (“if true”) Boolean expression (“condition”) second expression (“else if false”) A simple example: int x = 0; x = x > 0 && x 10 ? x : 10 This code snippet sets the value of x to 10 if it is greater than or equal to 0 or less than 10.

Ternary Operator || in Java

The logical OR operator is a binary operator that evaluates a boolean expression and then returns the value of the first expression if and only if the second expression is false.

The general form of this operator is: Boolean expression (“condition”) first expression (“if true”) Boolean expression (“condition”) second expression (“else if false”) A simple example: int x = 0; x = x > 0 || x 10 ? x : 10 This code snippet sets the value of x to 10 if it is greater than 0 or less than 10.

If you’re coming to conditional operators from another programming language, you might not find anything particularly unusual about them – they’re just like most other ternary operators in other languages.

But if this is your first time encountering these types of operators, it’s worth reading through this article to get familiarized with them and understand how to use them effectively in your code. Now, it’s time to put these conditional operators to use in your code.

When you’re writing code, you’ll often find yourself having to make choices. If you’re working with a programming language that supports conditional operators, you can use these operators to reduce the number of lines of code you need to write and make your code more readable and maintainable.
