The Conditional Operator

The most complicated conditional statement in Java is the ternary operator ?.

You can use the ternary operator when you want to assign a value or dis-

play a value based on a condition. For example, consider a video game

that sets the numberOfEnemiesvariable based on whether the skillLevel

variable is greater than 5. One way you can do this is an if-elsestate-

ment:

if (skillLevel > 5) {

numberOfEnemies = 10;
