java类中有啥错
package javaapplication4;
class Point {
private int x;
private int y;
private int z;
public void p(){
System.out.println("("+getx()+","+gety()+","+getz()+")");
}
public void Po(int a,int b,int c){
return a*a+b*b+c*c;
}
public int getx(){
return x;
}
public void setx(int a){
x=a;
}
public int gety(){
return y;
}
public void sety(int b){
y=b;
}
public int getz(){
return z;
}
public void setz(int c){
z=c;
}
}
public class Main {
public static void main(String[] args) {
Point point =new Point();
point.setx(1);
point.sety(2);
point.setz(3);
point.p();
System.out.print(point.Po(1,2,3));
}
}
po函数说错了 大哥告诉我那里错了
