Question

Bit of a wierd requirement.

public class DummyClass{
   public static final DummyClass var1;
   public static final DummyClass var2;
   public static final DummyClass var3;
    .
    .
    .
   public static final DummyClass var100;
}

Now from outside of this class can we pool this var’s into a single array or list, so that I can iterate over them? Like if i do something like

List<DummyClass> dummyList = *some op*; //I want value of some op.

I should be able to access var1…var100

You could use reflection:

Field[] fields = DummyClass.class.getDeclaredFields();
for (Field f : fields) {
    if (Modifier.isStatic(f.getModifiers()) && isRightName(f.getName())) {
        doWhatever(f);
    } 
}
