Student Enrollment System in Java

Student Enrollment Program written in Java will allow getting students enrolled for the various semester and will allow to choose them there subjects for a semester and will generate fees.

The above code is designed for educational institutes and coaching classes where students will be able to select their subjects according to their choice in the semester.

The students can select their semester accordingly n also can select their subjects according to their interests.

If more subjects have been selected by the students then they have to pay more accordingly and if less are selected they have to pay less.

In this code fake currency has been provided to pay the fees to the respected institute. It also gives the remaining balance of the fake currency.

The code uses various concepts of JAVA such as Constructors, function overriding, the array of objects, exception handling, etc.
