Can a Ternary Operator Replace an If-Else Statement That Doesn't Return a Value?

Ternary Operator: Replacing if-else with Conditional Expressions

In programming, the ternary operator provides a concise way to express conditional statements in a single line. Consider the following code:

if (string != null) {
    callFunction(parameters);
} else {
    // Intentionally left blank
}

Can we convert this to a ternary operator?

Using the Ternary Operator in Java

The ternary operator in Java follows the syntax:

return_value = (true-false condition) ? (if true expression) : (if false expression);

Applying to the Given Code

Based on the assumption that callFunction(...) does not return a value, we cannot use the ternary operator for this particular code block. Ternary operators are typically used for alternative assignments, which is not the case here.

Alternative if-else Statements

Depending on the intended behavior, here are alternative ways to refactor the code:

If callFunction(...) Returns a Value:

return_value = (string != null) ? callFunction(...) : null;

If callFunction(...) Does Not Return a Value:

if (string != null) {
    callFunction(...);
}

Or, as a one-liner:

if (string != null) callFunction(...);

Best Practices for Ternary Operators

Remember, ternary operators should primarily be used for alternative assignments. Avoid using them unnecessarily, as they can reduce code readability.

Additional Note

If the false clause is intentionally left blank, consider using the more concise one-liner version.
