Java Program Given partial codes of the Colored interface and Point class as the following: //Colored interface public interface Colored{ public String getColor(); } //Point class public class Point { private int x; private int y; public Point() { this(0, 0); } public Point(int x, int y) { setLocation(x, y); } public boolean equals(Object o) { if (o instanceof Point) { Point other = (Point) o; return x == other.x && y == other.y; } else { return false; } } public void setLocation(int x, int y) { this.x = x; this.y = y; } public String toString() { return "(" + x + ", " + y + ")"; } } Write ColoredPoint class so that implements the Colored interface and extends Point so that Points have colors. Override toString method to print out the coordinates and color of the point, override equals method so that it compares color as well. And write the necessary constructors, accessors and mutators. Write a client class and create objects of the ColoredPoint class. Print out the colored point and compare if they are equal.

Question
Java Program
Given partial codes of the Colored interface and Point class as the following:
//Colored interface
public interface Colored{
public String getColor();
}
//Point class
public class Point {
private int x;
private int y;
public Point() {
this(0, 0);
}
public Point(int x, int y) {
setLocation(x, y);
}
public boolean equals(Object o) {
if (o instanceof Point) {
Point other = (Point) o;
return x == other.x && y == other.y;
} else {
return false;
}
}
public void setLocation(int x, int y) {
this.x = x;
this.y = y;
}
public String toString() {
return "(" + x + ", " + y + ")";
}
}
Write ColoredPoint class so that implements the Colored interface and extends Point so that
Points have colors. Override toString method to print out the coordinates and color of the point,
override equals method so that it compares color as well. And write the necessary constructors,
accessors and mutators.
Write a client class and create objects of the ColoredPoint class. Print out the colored point and
compare if they are equal.
