What is the purpose of declaring a variable as final?

August 15th, 2009 by uCertify Leave a reply »

In Java, final is a keyword. The value of a variable declared as final remains unchanged in an application. This means that the variable should be initialized at the time of its declaration.

The syntax for declaring a variable as final is given below:

final <data-type> <variable-name>

Note: It is similar to const in C and C++.
