OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Procedure: 1. Develop a simple program for an individual savings account. Create two (2) classes named AmountDue (no class modifier) and RunAmountDue (public). 2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based on the following conditions: • With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and return the total due. With two (2) parameters: These represent the price of an item and the quantity ordered. Multiply the two (2) values, add 12% tax, and return the total due. With three (3) parameters: These represent the price of an item, the quantity ordered, and the discount amount.
