下面这个程序不能运行，大家帮我看一下哪儿出错了，谢谢了！
class Point{
double x,y,z;
Point(double _x,double _y,double _z){
x = _x;
y = _y;
z = _z;
}
void setX(double_x){
x = _x;
}
double getdistance(Point p){
return x = (x-p.x)(x-p.x)+(y-p.y)(y-p.y)+(z-p.z)(z-p.z);
}
}
public class TestPoint{
public static void main(String[] args){
Point p = new Point(1.0,2.0,3.0);
Point p1 = new Point(0.0,0.0,0.0);
System.out.println(p.getdistance(p1));
p.setx(5.0);
System.out.println(p.getdistance(new Point(1.0,1.0,1.0)));
}
}
