Static binding is nothing but Late binding and vise versa.

Static Binding: if the binding is occur at compile time of our source code is called static binding

Dynamic Binding: if the binding is occur when interpreter our class fine then that binding is called Dynamic Binding.

1. Statis Binding : Initialize the variable like private static HashMap map new HashMap();

2. Dynamic Binding: Initialize the variable like private HashMap map; and somewhere in the method do map new HashMap();

Please let me kknow if any change is there...!
