Java: define terms initialization, declaration and assignment

Question

I find the defs circular, the subjects are defined by their verbs but the verbs are undefined! So how do you define them?

The Circular Definitions

Answer 1

Step 1: Declaration : int a;

Step 2: Initialization : a = 5;

Step 3: Assignment: a = b; (ex: int b = 10 ; now a becomes 10)
