关于switch语句的

[t427795737]

这段程序的输出为什么是 Value is two.
Value is three.

怎么不是 Value is two.
Value is 2

public class SwitchTest
{
public static void main(String[] args)
{
int j = 2;
switch ( j )
{
case 2:
System.out.println("Value is two.");
case 10:
System.out.println("Value is three.");
break;
default:
System.out.println("Value is " + j);
break;
}
}
}

回去看看switch吧.

case 2:
System.out.println("Value is two.");
------------------------------------------
在这句后面加上 break;
case 2:
System.out.println("Value is two.");

break;

public class SwitchTest
{
public static void main(String[] args)
{
int j = 2;
switch ( j )
{
case 2:
修改处 System.out.println("Value is two.");
break;
case 10:
System.out.println("Value is three.");
break;
default:
System.out.println("Value is " + j);
break;
}
}
}

好奇怪的问题
为什么你能记得在case 10后面家break，而想不起来在case 2后面也加上呢？？＃

原谅一下，可能是菜鸟，我以前学C的时候班里同学比这CUO 的都有。

case 2:
System.out.println("Value is two.");
后面加个break;
