24 Java语言基础逻辑运算符&&和&的区别

 1 public class HelloWorld {
 2 public static void main(String[] args) {
 3 
 4 int x = 3;
 5 int y = 4;
 6 System.out.println((++x == 3) &( ++ y ==4)); // false 与 false 结果为false 
 7 System.out.println("x="+x);
 8 System.out.println("y="+y);  // y =5
 9 
10 
11 System.out.println((++x == 3) && ( ++ y ==4)); // false 与 false 结果为false 
12 System.out.println("x="+x);
13 System.out.println("y="+y); //y = 5  因为短路,y没有参不与运算
