There are a number of things wrong in your code, which make it so that it does not compile - for example, there are typos such as "viod" instead of "void", "Static" instead of "static" (Java is case-sensitive), and forgetting to put a parameter list behind a method name (for the method named "one"). Please post correct code, otherwise it will become harder to help you.
Member variables and methods that are static are class-level variables and methods instead of object-level - unlike non-static variables and methods, they don't work on a specific object, but are shared between all objects of the class.
If you have a static method one(), then you cannot call a non-static method three() without specifying on which object you want to call the non-static method. So, that's why line 7 doesn't work.
Likewise, lines 8 and 19. The method four() is non-static. You cannot call it without specifying on which object you are calling the method.
