Static Functions
Methods also can be static. Let’s create compare() method with two parameters: studentA and studentB. This function will output which student has a higher GPA.
To call this method, you also have to use the name of the class, not the object:
Inside the static method, you can refer only to static class attributes, using this keyword, because non-static attributes are unique for each object, so for the whole class, they are undefined.
Note that in function compare() you refer to the non-static objects attributes studentA and studentB, but to the static class attributes Student.
Everything was clear?
