Objective variables are defined to construct an objective function. The objective function is a summation of all variables that are designated as objective-type. Variables are defined as objective function contributions by starting with obj. Thus, the variables obj1, objective, object[1] would be included in the objective function summation.

Additionally, slack variables are included in the objective function. These variables begin with the key letters slk and are defined with a lower bound of zero.

Uses:-

The objective function is always minimized with APMonitor. Maximizing an objective function is accomplished by minimizing the negative of the original objective.

Where the abstract variables are used in java, A concept or idea not associated with any specific instance. A sketchy summary of the main points of an argument or theory. There is nothing like 'abstract variable' in Java. Abstract implies that the abstract methods within abstract classes must be coded.

I will create different classes for different db tables. Each class should have it's own TABLENAME variable, no exception. I have to make sure this variable is static each time when I create a new class that extends the abstract class.

Then in the abstract class I will have a method eg: init();

If in this init() method I call TABLENAME, it should take the value from the sub-class.

something like this should also work out.
