How to Use Java Conditional Operator (Shorthand If-Else Statement) for Beginners
How to use Java Conditional / Ternary Operator or Shorthand If Else Statement for Beginners -
In Java, sometimes when manipulating variables, you want to set a variable's value depending on a condition. While you can do this with an if-else statement, it's lengthy and takes up at least four lines of code. You can easily condense this code using a ternary operator to just one line.
Note that Ternary Operator is Also Known as Shorthand If Else Statement and Conditional Operator. It's the same thing. :)
Java Ternary Operator Basic Syntax:
variable = (condition)? valueIfTrue: valueIfFalse;
For example, given the condition 5==4, you want to set int x equal to 5 if true, or 4 if false.
With an if statement, that looks like this:
if(5==4){
x = 5;
}else{
x = 4;
}
It's doable, but it's wordy and takes up a lot of space. This can easily be condensed with a ternary operator, which looks like this:
x = (5==4)? 5:4;
Since 5 is not equal to 4, the condition is false, and thus it will set x equal to the valueIfFalse, 4.
I hope this helps!
