A static method in java is also named a class method, because it does not need an instance (of his class) to be invoked.
Static methods can't use instance variables (non static variables) or use the keywords 'this'. These methods receive all the information they need to complete his task from his parameters

No other static method could replace it's functionality. PS By static method do you mean static initialiser? I often use static initialisers instead of a main method, but in these cases you must still have a main method, albeit an empty one ie. public static void main(String[] args) {} Notice that the method has an empty body A main method must be used if you intend to accept parameters at run time from the jvm.
