if...else if...else 语句

只要第一个条件满足，就不会走下面的判断了。

代码如下：

public class Test {
   public static void main(String args[]){
      int x = 30;
      int y = 20
      if( x == 10 ){
         System.out.print("Value of X is 10");
      }else if( y == 20 ){
         System.out.print("Value of Y is 20");
      }else if( x == 30 ){
         System.out.print("Value of X is 30");
      }else{
         System.out.print("这是 else 语句");
      }
   }
}

 输出为：Value of Y is 20

并不会输出：Value of X is 30
