Ternary Operator in Java
What Is It?
The ternary operator is a shortcut in Java for choosing between two values based on a condition. It makes code shorter and easier to read.
Syntax:
condition ? expression1 : expression2;
Explanation of this code:
The condition is a boolean expression that is evaluated.
If the condition holds true, the system outputs expression1.
When the condition is false, expression2 is returned.
The ternary operator can be handy in situations where the condition and expressions are straightforward and do not involve complex logic or multiple branches. However, for more complex scenarios, using if-else statements might be more readable and maintainable.
Three operands are required for the ternary operator: condition, expression1, and expression 2. Hence, the name ternary operator.
Example
Let’s say we want to check if someone is old enough to vote:
This example checks the age and uses the ternary operator to quickly say “Yes” or “No”.
When to Use It
Use the ternary operator when you have a simple yes/no decision. It’s great for quick checks and assigning values based on those checks.
Simple Tips
- Keep it simple. If your check or the values get complicated, it’s better to use a regular
if-elsestatement. - Don’t overuse it. While it’s handy, using it too much can make your code hard to follow.
The ternary operator helps keep your Java code neat and tidy, perfect for making quick decisions between two options.
