Java - Cannot resolve constructor

I am new to Java programming. I have three classes which are Main, Point and Rectangle. I can use all constructors in Rectangle class except this one: Rectangle(Point p, int w, int h). Java compiler gives: "Cannot resolve constructor 'Rectangle(java.awt.Point, int, int)'" error. Thanks.

Here my classes:

Main.java

import java.awt.*;
import java.awt.Point;
import java.awt.Rectangle;

public class Main {

    public static void main(String[] args) {
        Point originOne = new Point(5,10);   
        Rectangle rectOne = new Rectangle(originOne, 100, 200);
    }

}

Point.java

public class Point {
    public int x = 0;
    public int y = 0;
    //contructor
    public Point(int a, int b){
        x = a;
        y = b;
    }
}

Rectangle.java

public class Rectangle {
    public Point origin;
    public int width = 0;
    public int height = 0;

    //four contructors
    public Rectangle() {
        origin = new Point(0, 0);
    }
    public Rectangle(Point p){
        origin = p;
    }
    public Rectangle(int w, int h){
        origin = new Point(0,0);
        width = w;
        height = h;
    }
    public Rectangle(Point p, int w, int h) {
        origin = p;
        width = w;
        height = h;
    }

    // a method for moving the rectangle
    public void move(int x, int y) {
        origin.x = x;
        origin.y = y;
    }

    //a method for computing the area of rectangle
    public int getArea() {
        return width * height;
    }
}

Your answer is fairly simple. You've imported the wrong import, rather than import java.awt.Rectangle, import your own class.

By doing:

import <nameOfTheProject>.Rectangle;

If I had a project in Eclipse called MyShapes and had the same classes. I would import it like:

import MyShapes.Rectangle;

Now this obviously depends on how your file structure is, but if it's inside a sub-folder (sub-package), I would do like:

import MyShapes.ShapesClasses.Rectangle;

This also applies to the Point class if you're planning on using your own Point class and not Java.awt's one!
