Can I write a code only using static(class) methods?

So my question is based on my homework instruction.

The professor wouldn't answer instantly so here I am!

"Use static (class) methods to create and print 2-dimensional arrays of characters in different patterns." That is the objective of the assignment.

That does mean I have to write the code only using public class () iAmDumbSorry methods?

Or am I misunderstanding something?

Sure, it is possible to write java code that solely relies on static fields/methods.

But the point is: static has various implications, as it simply kills your ability to override methods. In other words: static-only means: no polymorphism. Which makes using an OOP language almost pointless.

Sometimes an education plan starts with "static only", assuming that this is easier for students to follow. And then the non-static things are excluded, and explained later on.

So your code would look like this:

class Foo {
  static int someInt;
  static void bar() { ... }

and 

public class Main {
  public static void main(... {
    Foo.bar();
    if (Foo.someInt == ) ..

Long story short: take this unclear assignment as motivation to learn about the differences between static and non-static, and see what effects it has on your ability to express your thoughts in code.

Yes, those classes are called utility classes. You can compare it to the java.util.Collections which consists only of static methods.
