Change value of static field in a static method

Question

I have a SampleClass with static field a and b and a static method init. To re-create SampleClass with new value for a and b, I use below syntax:

public class SampleClass{

    private static int b;
    private static int a;
    
    public static void init(int a, int b) {
        SampleClass.a = a; //line 7
        SampleClass.b = b; //line 8
    }
}

I actually feel awkward about line 7 and line 8. Is this acceptable or there are more correct ways to do this?

I feel awkward calling the SampleClass within the SampleClass. It does what I need to do but I am not sure if there is an effect using this convention — NothingBox

I'm not sure how to address you confusion because it's unclear but I can tell you that there's nothing inacceptable with the lines. — akuzminykh

SampleClass.a = a; is the recommended way if the variable name conflicts. — Naruto

Your syntax is not wrong.

For static attributes, you either use the syntax you have provided in your question, either you assign different names for your parameters (for code self-explanatory reasons). For instance:

public static void init(int newA, int newB) {
    SampleClass.a = newA;
    SampleClass.b = newB;
}

It won't work because it will throw Cannot use this in a static context

I think you're basically ignoring the question and just dump information about setters.

You're right, I did a tremendous mistake. I didn't ignore his answer, but I wanted to clarify some aspects.

@DavidBuzatu Okay, well done. But now don't just edit your answer with an excuse and don't keep the wrong part. Just give it a small rework so it answers the OP's question without any noisy text.

Yes, it's acceptable. In fact if you generate a Setter method for a static field, the assign way will also be SampleClass.a = a.
