How do you give a value dynamically in Java?

There are no dynamic variables in Java. Java variables have to be declared in the source code1. Depending on what you are trying to achieve, you should use an array, a List or a Map ; e.g. It is possible to use reflection to dynamically refer to variables that have been declared in the source code.

How do you initialize a dynamic variable in Java?

What is static and dynamic value?

In general, dynamic means energetic, capable of action and/or change, or forceful, while static means stationary or fixed. In computer terminology, dynamic usually means capable of action and/or change, while static means fixed.
