    I have to import those three classes.


    import android.graphics.Color;

    import android.graphics.Paint;

    import android.graphics.Canvas;


    And I will simply import all of that by

    import android.graphics;



    So, I have a question.


    Why a developers import each of them one by one ?

    Why not just import like import android.graphics; ?


    This way will take much more time and memory ?


    Oh, I know this is basic question, but I want to know a reason..


    Thanks.

    I see, so prevent duplicate method name (name space issue) , right ?

    Well I think it's good to import specific classes, to avoid possibly the same class name in different packages.

    Doesn't it keep the whole project smaller to? If you are using only one method from a lib then why import the whole thing if you just want one method from a .somthingorother

    It's probably more efficient to import specific classes, but in terms of class loading, then the JVM only imports what it needs at runtime. I don't think it actually makes a whole lot of difference tbh.
