    Default Help with moving an object in Java?

    Hello all,
    Could someone give me some advice on how to tackle this problem please - thank you in advance. So basically I have a program that paints a simple object image. There are 5 of these objects altogether and different classes and methods have been set up to do this and this works correctly. The program currently also asks the user if they would like to change the colour of this object shape, and which shape they would like to change (user inputs a number 1-5) then the program will change the colour of this shape.

    But the new task is for the user to input a number (1-5) to which shape they would like to MOVE position of. Any ideas on how this would be done? Would there need to be different methods for changePositionX, changePositionY? The user needs to input the X and Y co ordinates and then this will move the selected shape to its NEW position in the current JFRAME.
    Thank you, if any code is needed I will paste it in.

    I would paint the shapes on a JPanel which is then added to the JFrame. Each shape change entered by the user, color, x/y position - whatever - affects the attributes of the shape(s) which are then redrawn in the JPanel's paintComponent() method. These techniques are discussed in the Java Tutorials in the Custom Painting topic.
