Java problem defines a Point class
Define a Point class, the member variables are x, y, and the member function set() is set The value of x, y, get() gets the value of x, y, and defines a point object to call set() and get(), and defines a point object to call set() and get() constructor overload, distance( ) represents the distance between 2 points.
Example
public class Point { private int x; private int y; public Point(int x, int y) { this.x = x; this.y = y; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public double distance(Point p1,Point p2){ return Math.sqrt((p2.getX()-p2.getX())*(p2.getX()-p2.getX())+(p2.getY()-p1.getY())*(p2.getY()-p1.getY())); } public static void main(String args[]){ Point p1 = new Point(14,17); Point p2 = new Point(23,90); double s = p1.distance(p1,p2); System.out.println("2点之间的距离为:"+s); } }
