这样写程序对吗？

[huanxiangrushui]

/*MyPoint*/
public class MyPoint{
public class Static Void main (String arg[]){
class MyPoint {
int x;
int y;
}
MyPoint start;
start = new MyPoint();
MyPoint end;
end = new MyPoint();
start.x = start.y = 10;
end.x = end.y = 20;
System.out.println ("Start MyPoint = x:"+start.x+"y"+start.y);
}
}

错了好多地方
1。 class Static Void main
2。 class MyPoint
。。。
没办法改了

[feiyuwen]

public class MyPoint{
public static void main (String arg[]){
class inner {
int x;
int y;
}
inner start;
start = new inner();
inner end;
end = new inner();
start.x = start.y = 10;
end.x = end.y = 20;
System.out.println ("Start inner = x:"+start.x+"y"+start.y);

System.out.println ("end inner = x:"+end.x+"y"+end.y);
}

看了你的代码觉得不对劲，反正按照你的要求改了一下，运行通过.
我也是初学，请高手指教
public class MyPoint{
int x;
int y;

public static void main (String arg[]){

MyPoint start;
start = new MyPoint();
MyPoint end;
end = new MyPoint();
start.x = start.y = 10;
end.x = end.y = 20;
System.out.println (start.x);
}
}

谢谢大家，非常感谢！！

public class MyPoint{
int x;
int y;

public static void main (String arg[]){

MyPoint start = new MyPoint();
MyPoint end = new MyPoint();
start.x = start.y = 10;
end.x = end.y = 20;
System.out.println ("Start MyPoint x=" + start.x);
System.out.println ("Start MyPoint y=" + start.y);
System.out.println ("End MyPoint x=" + end.x);
System.out.println ("End MyPoint y=" + end.y);
}
}
以上是我帮你修改的.望高手指点！！
