* Overriding paintComponent, can do this due extending class JComponent
* paintComponent is a part of JComponent
* A method very similar to TextStatistics Input is used to iterate through the ascii table for the letters and numbers
* first g.drawRect has 4 input variables. X Y positioning and WEIGHT and HEIGHT
* it is important to understand that the rectangles extend downwards starting from 0
* that's why getHeight() is used
* after g.drawRect to draw strings on top of the rectangles g.drawString was used
