Patterns to instantiate abstract class?

I have an abtract class lets call it ClassAbstract.

I also have a number of concrete classes Class#NonAsbtract extends ClassAbstract.

Consider the following piece of code:

public void someMethod(some arguments) {
    // my solution : ClassAbstract ca = buildClassAbstract(enumArgument);
    ClassAbstract ca = new Class#NonAsbtract();
}

Right now I am using this method in the same class with someMethod:

private ClassAbstract buildClassAbstract(SomeEnum enum) {
    switch(enum) {
         case ARG_ONE:
              return new Class1NonAbstract();
    }
}

Do you think it's worth it to go to any pattern

You are looking for Factory pattern. You almost did it, just create factory class and move your buildClassAbstract method to it.
