◕ What is the difference between the Initialization and the Assignment in Java?

■ Initialization causes a variable to have the value that you specify when it is created.

int flower = 786;
This is the Initialization of the variable flower.

Why Initialization is important in Java?

■ On the other hand an assignment involves copying data from one place to another in memory.
In normal practice, we have to declare and initialize variables before using them in the assignment statement.

a = b + c ;

Here the values of the variables b & c are added and final result is stored in the variable a.

The equal sign ' = ' is called the Assignment Operator.

Please note:

a = b = c = 123;
What is the above statement? An Initialization or an Assignment statement?

Ans:- This is an assignment statement.
Because the compiler allocates some memory to store the constant 123 as type int in the variable c.
The value in c is extracted and copied to b. Then again the value in b is copied to a.
