How does the Ternary Conditional Operator work in programming?

Understanding the Ternary Conditional Operator

In programming, the question mark ("?") and colon (":") operators are used within parentheses to form the ternary conditional operator. It offers a concise alternative to the traditional if-else statement, allowing you to evaluate a condition and assign a value based on its truthiness.

Syntax and Usage

The ternary operator follows the syntax:

boolean_expression ? true_value : false_value

If boolean_expression evaluates to true, the true_value is assigned; otherwise, the false_value is assigned.

For example:

<code class="java">int result = x > 0 ? 1 : 0;</code>

If x is greater than zero, result will be assigned 1; otherwise, it will be 0.

Alternative to if-else Statements

The ternary operator provides a more compact way to write simple if-else statements. Consider the following example:

<code class="java">if (row % 2 == 1) {
    System.out.print("<");
} else {
    System.out.print(">");
}</code>

This code can be rewritten using the ternary operator as:

<code class="java">System.out.print(row % 2 == 1 ? "<" : ">");</code>

Terminology and Documentation

The ternary operator is often simply referred to as "the ternary operator" or "conditional operator." More information on its use can be found in the documentation for the programming language you are utilizing, such as Java's documentation on the ? operator.
