The order of the class initialization:
1. static variables and static blocks, based on the order they appear in the class (this only happens at the first time the class is accessed)
2. the non-static variables
3. constructor

The above steps (1 through 3) are repeated top-down in the class inheritance tree. For example, if class A is the sub-class of B and B is the sub-class of the root class Object, then the following initialization will occur when you call A a = new A();:
i) do step 1 through 3 for the root class Object
ii) do step 1 through 3 for class B
iii) do step 1 through 3 for class A
