Java Basic(20)-Conditional Operators條件運算符

class apples{

public static void main(String args[]){

int age = 21;

System.out.println(age > 50 ? "You are old" : "You are young"); → boolean

}

}

是什麼意思：

(age > 50 ? "You are old" : "You are young");

age > 50 → 這是條件

? → 如果是TRUE

“You are old” → 執行這個

: → 如果是FALSE

“You are young” → 執行這個

在這個方案中，age是21，所以它在這個Boolean假的，所以會顯示：

You are young
