This document contains the source code for an integration project that allows a user to choose from 18 different programs to run. It includes methods for tasks like echoing input, integer division, finding the birthday month from a number, running a for loop, working with arrays and array lists, and an example of inheritance with a Car class extending a Machine class. The main method uses a switch statement to call the appropriate method based on the user's selection and ensures the programs can be continuously run with a while loop.
