public class SystemTest { public static void main(String[] args) { System system = new System(); } 能帮个忙吗?漏了,重新写过吧:public class SystemTest{ public static void main(String [] args) { System system = new System();
public class SystemTest { public static void main(String[] args) { System system = new System(); }
能帮个忙吗?
漏了,重新写过吧:
public class SystemTest
{
public static void main(String [] args)
{
System system = new System();
system.output;
}
}
class System
{
public void output()
{
System.out.println("output");
}
}
郁闷中,我将此程序在Eclipse中重写时,编译通过.但用dos命令符编译时出现上图的错误,不知是不是个人环境变量配置出现问题,还是其他的?
public class SystemTest { public static void main(String[] args) { System system = new System(); } 能帮个忙吗?漏了,重新写过吧:public class SystemTest{ public static void main(String [] args) { System system = new System();
由于你已经重写了System类 所以你System.out.println的时候 out在你定义的System里面没有 所以出现异常 你可以自己定义的System类去继承System类
没试过 理论. 不过这样只是玩玩的 没有哪个搞开发的会去重写System类的
