Java 8：更好地扩展静态方法类或更好地直接调用静态方法？

例如：

public class BaseClass{
     /* this class has a huge amount of ONLY static methods/constants */

     public static final int STUFF_DONE = 1;

     public static String getStuff(){
           String stuff = "this is my stuff.";
           return stuff;
     }
     ...
}

public class SuperClass extends BaseClass{
     /* this class has only a few methods */
     public String labelStuff(){
          return getStuff();
     }
}

public class MyClass extends SuperClass{
     /* there are many classes that extend SuperClass like this one */
     public int handleStuff(){
          String myString = labelStuff();
          return STUFF_DONE;
     }
     public static void main(){
          if(handleStuff()) System.out.println("Done.");
     }
}

我的问题是……保持这种设计是否更好,或者更好地删除静态方法/常量的继承并简单地静态调用这些方法/常量？

对我来说“更好”被定义为较低的内存消耗(同样,这个基类非常庞大),因为CPU很可能不受此影响.这种方法有哪些好处/陷阱？

我担心的是,因为BaseClass是如此巨大,以至于我在继承类中只使用一两个方法/常量浪费了大量内存,我可以静态调用它.
