Is this what you had in mind?

Answer 2

I see that this is JAVA, but where did you learn to program?

first line utl should be util

a Scanner sc = new a();
//???????????????? HOW AND WHY?

When you Initialize a new instance you'll need to assign it to a variable like this:

a myA = new a();
same with the other few lines in the Main function.

The classes are just wrong.
Are you mixing Java with Python?

Please do the courses again, I'll see what I can do around this code of yours
