条件运算符(?:)

条件运算符也被称为三元运算符。该运算符有3个操作数,并且需要判断布尔表达式的值。该运算符的主要是决定哪个值应该赋值给变量。

variable x = (expression) ? value if true : value if false

代码:

public class Test {//公共测试类,与文件名相同	public static void main(String[] args){//main程序入口        int score = 80;         int x = -100;        String type =score<60?"不及格":"及格";         int flag = x > 0 ? 1 : (x == 0 ? 0 : -1);        System.out.println("type= " + type);        System.out.println("flag= "+ flag);}}

运行效果:
