Creating a Point.class

Hey everyone,
I have an assignment that's due tomorrow and I am completely stuck and was hoping to get some help. My assignment is to create a Point object that represents an x,y point. Here is an outline of the object that the teacher gave us. Any help would be much appreciated! -Jon

The instance data stores its x and y coordinates.
The constructor lets you set x and y when you create a Point.
There is a method called getX for asking a Point what its x-coordinate is.
There is a method called getY for asking a Point what its y-coordinate is.
There is a method called setXY that lets you change the coordinates of a Point.

Have you looked at the java SE's Point class? The name Point is used by the Java SE. Using the same name will cause confusion.

What have you tried?

Hey Norm,

I was unaware of this, but my teacher specifically asked us to label the new class "Point". Here is what I have gotten so far

public class Point {

private int x, y;

public Point(int x, int y) {

}

public int getX() {

return x;

}

public int getY() {

return y;

}
}

So I have my instance data, constructor, but am not sure of how to tie in x,y data to the getX and setXY. I know it is not much of a start and probably contains some errors, but I am at a dead end. And sorry about the vagueness of the first post. I am not looking for you to write my code for me. I just need some direction. Thanks for your time. -Jon

The constructor needs to save the x,y values it receives.
The get method should return the current value of the variable. Yours look OK.
setXY() would be similar to the constructor: save x and y

When you post code, please wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

Thanks, that helped a lot. I am now stuck on the setXY() section and was wondering how setXY() works? Do you need user input and use the Scanner class? -Jon

Ask your teacher what he intended. I suggested that setXY() do the same as the constructor.

Awesome Norm, just finished the program. Thanks for your help. Sorry for my lack of java and forum ettiquette, I am new to the game. -Jon

No problem. I'm sure you'll improve with more experience.
