标题: 关于switch的用法，看完这些例子包你会
class SwitchDemo {
public static void main(String[] args) {
int x=8;
switch(x)
{
case 0:
System.out.println("0成功");
case 1:
System.out.println("1成功");
case 2:
System.out.println("2成功");
case 3:
System.out.println("3成功");
case 4:
System.out.println("4成功");
case 5:
System.out.println("5成功");
case 6:
System.out.println("6成功");
case 7:
System.out.println("7成功");
case 8:
System.out.println("08成功");
default:
System.out.println("都失败");
}
}
}运行结果：08成功 都失败

最后再加一句，JDK1.7之后增加的字符串类型也和上面一样哦。
