Java问题烦劳大家：定义一个点类(Point)

public class Point {

private double x;
private double y;

public double getX() {
return x;
}
public void setX(double x) {
this.x = x;
}
public double getY() {
return y;
}
public void setY(double y) {
this.y = y;
}
public double distance(){
return Math.sqrt(x*x+y*y);
}

}
//测试类
import java.util.Scanner;

public class Test {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.println("请输入一个点的X轴坐标：");
double x=input.nextDouble();
System.out.println("请输入一个点的y轴坐标：");
double y=input.nextDouble();

Point point=new Point();
point.setX(x);
point.setY(y);
System.out.println("该点的坐标为:"+point.getX()+","+point.getY());
System.out.println("该点到原点的距离为："+point.distance());
}

}
