UC知道求java高手帮我改一下下面程序：

public abstract class Shape extends Object {
public double area()
{
return 0.0;
}
public double volume()
{
return 0.0;
}
public abstract Sting getName();
}
//definition of class Point
public class Point extends Shape{
protected int x,y;
public Point()
{
setPoint(0,0);
}
public Point(int xcoordinate,int ycoordinate)
{
setPoint(xcoordinate,ycoordinate);
}
public void Point(int xcoordinate,int ycoordinate)
{
x=xcoordinate;
y=ycoordinate;
}
public int getX()
{
return x;
}
public int getY()
{
return y;
}
public String toString()
{
return "["+x+","+y+"]";
public double area()
{
return 0.0;
}
public double volume()
{
return 0.0;
}
public abstract Sting getName();
}
//definition of class Point
public class Point extends Shape{
protected int x,y;
public Point()
{
setPoint(0,0);
}
public Point(int xcoordinate,int ycoordinate)
{
setPoint(xcoordinate,ycoordinate);
}
public void Point(int xcoordinate,int ycoordinate)
{
x=xcoordinate;
y=ycoordinate;
}
public int getX()
{
return x;
}
public int getY()
{
return y;
}
public String toString()
{
return "["+x+","+y+"]";
第一个错误：
public abstract Sting getName();
拼写错误：String；
第二个：
没找到setPoint()；加个此方法；
第三个：
protected double weight,height;
public Rectangle()
{
setRectangle(0.0,0.0);
}
public Rectangle(int xcoordinate,int ycoordinate,double weight,double height)
{
super(xcoordinate,ycoordinate );
setRectangle(w,h);
}
前面声明的变量是weight,height，下面却用w，h，改下；
第四个：
return "Center="+super.tostring()+"; weight="+weight+";height="+height;
toString()中S要大写。
第五个：
return "center="+Point.super.toString()+";Radius="+Radius;
变量Radius的r应该是小写的。
这代码郁闷呀兄弟。以后写程序认真点。
