Good day everyone!

I am currently a college student who is enrolled in a computer course. One of my subjects is Java. I am new to this programming language since this is the first time I am actually using the language. Recently, my professor has required for us to work on an MP (Machine Project) with certain specifications. It is a program written in the Java Language which is similar to Facebook's Photo Tagger; where the user uploads an image and when the user clicks on a certain area in the image, a box will appear and you can tag someone.

So my request is this, maybe some of you people may have a few tips and tricks for me since I have no idea how to start my Project. I already have a GUI and it already has the code JFileChooser. However, I do not know how to show the image I select in a label. Might I have some help with this.
