final means constant

Posted by Kishori Sharan on January 11, 2001 at 12:44 PM

final int i = 100 ;
This makes i a constant. After this declaration if you try to assign a different value to i as in
i = 101 ; you will get error because value of 100 is the final value of i. i cannot be changed afterwards. Some languages use keyword CONSTANT instead of final.
Whereas int i = 100 ;
declares a variable i of type int and initializes it to 100. In this case you can chage the value of i whenever you want lieks
i = 200 ;
