1) Take a look at source of Vector to see how it is done. The sources of the java classes are typically coming with each JDK in a src.jar or src.zip file. 2) It is not possible to declare a non-public, non-static, non-final field in an interface.

Use an Abstract class either. It suits your interests better.
Whenever the capacity of the array gets filled a new array is created (double the size or increment value specified) and contents of the old array are copied to the newly created array.
