Categorization of keywords?

Question

I recently started to learn java, my only background is MIT App Inventor 2. I have been attempting to put each keyword (public, static, void, main, protected, private, int, etc..) in to categories pertaining to what they do. My only success has been in the fact that VOID replaces INT, DOUBLE, FLOAT, etc and does not return value, but it can do things such as print to the console... I am completely lost on the other keywords and would love some help or dummy-fying of their meanings / purposes and how each replaces/ compliments / relates to each other. Thanks!
