Write the code in java from the following given code using JOPtionPane.

Point.java

public class Point { //Declaring instance variables private int x,y;

//Zero Argumented constructor public Point() { super(); }

//Parameterized constructor public Point(int x, int y) { super(); this.x = x; this.y = y; }

//Getter and Setter methods 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; }

/* toString() method which displays * the contents of an object inside it */ @Override public String toString() { return "Point ("+ x + "," + y +")"; }

}
