Hello hasani6leap.
Every programmer has made a typo once. In my opinion, if you type less you make less typing mistakes. Today, a programmer does not have to type out everything. Many IDEs provide shortcuts by giving you a list of methods, code snippets and more to complete code for you. For example, NetBeans can create method definitions for methods that you still need to implement, if you press ctrl+space and choose the correct method. (shown with "-implement") Try looking into this. It might help.
