Can Ternary Statements Be Used Without Return Values in Java?

Ternary statements, also known as conditional operators, provide a convenient way to perform conditional expressions in Java. However, they typically involve a return value.

Is it Possible in Java?

Unfortunately, it is not possible to use ternary statements without returning a value in Java. The syntax requires a result on either side of the question mark, even if it is a placeholder like null.

Alternatives in Other Languages

While Java does not allow ternary statements without a return value, some other languages offer this functionality. For example, in Python, the ternary operator can be used with None to indicate no return value:

<code class="python">name.isChecked() ? name.setChecked(True) : None</code>

In JavaScript, the ternary operator can be used without a return value if the last branch is left empty:

<code class="js">name.isChecked() ? name.setChecked(true) : ;</code>

Why Not Use an If-Else Statement Instead?

In Java, using an if-else statement for a simple conditional statement like setting a checkbox to true or false is generally preferred over a ternary statement without a return value. Ternary statements are primarily useful for returning conditional values in expressions.

For instance, the following ternary statement returns a maximum value:

<code class="java">int max = a > b ? a : b;</code>

If there is no need for a return value, a simple if-else statement is more concise and easier to read.
