Short Hand If...Else

There is also a short-hand if else, which is known as the ternary operator because it consists of three operands.

It can be used to replace multiple lines of code with a single line, and is most often used to replace simple if else statements:

Syntax

variable = (condition) ? expressionTrue :  expressionFalse;

Instead of writing:

Example

int time = 20;

if (time < 18) {

  System.out.println("Good day.");

} else {

  System.out.println("Good evening.");

}

You can simply write:

Example

int time = 20;

String result = (time < 18) ? "Good day." : "Good evening.";

System.out.println(result);
