In the real world, an entire program is rarely written from scratch. It is very likely that there are classes or functions that already exist. The key to using these existing modules successfully depends on how modular the classes or functions are written. In this Learning Team assignment, your mission is to take a section of one team member’s Week Four program and replace a similar section of another team member’s Week Four program. Submit the following deliverables for this Learning Team assignment: A 700- to 1050-word paper describing the following: How the two programs were selected The process of identifying the classes or functions for replacement The changes needed to make the final Java™ application program work correctly The final Java™ application program (within a ZIP file) So this is a late minute assignment and I need this by tomorrow. I will be attaching two java program, 1 works and the other doesn't(saved in words). You can just combine whatever you need for the program to work.

Paper For Above instruction

In modern software development, reusing existing modules, classes, or functions is a common practice that enhances efficiency and reduces development time. For this assignment, two Java programs were selected—one that operates correctly and another that contains errors preventing it from running properly. The goal was to identify sections within these programs where modular code could be integrated, specifically replacing a failing section in the non-working program with a corresponding section from the working program. This process involves careful analysis of the structure of both programs, understanding the classes and functions involved, and making necessary adjustments to ensure seamless operation of the combined program.

The selection of the two programs was based on their functional similarity. Both programs were part of a coursework task focusing on basic Java features, such as user input, conditional statements, and simple calculations. The working program demonstrated proper implementation of class structures and method calls, while the non-working program lacked certain method invocations or contained logical errors that stopped it from executing correctly. The comparison helped in isolating the sections of code that could be modularized or replaced to improve the non-working program's functionality.

Once the programs were selected, the next step involved identifying the specific classes or functions intended for replacement. The non-working program contained a segment of code responsible for data input and processing, but it faced issues such as incorrect method calls or misaligned variable usage. The corresponding section in the working program was examined to understand how it successfully managed these tasks. Typically, these functions were encapsulated within classes or methods that handled user interaction and data processing effectively.

The process of modifying the non-working program involved extracting the functional section from the working program—such as a method that successfully collected and processed user data—and integrating it into the non-working program. This required adjustments to ensure consistency in variable names, method signatures, and class references. Additionally, to make the final Java application work correctly, it was necessary to resolve dependencies and ensure all relevant classes and functions interacted seamlessly. This often meant revising the main class to call the new methods appropriately and checking for any namespace conflicts or errors.

The final step was to compile the combined code into a Java project, make sure it compiles without errors, and test it thoroughly to verify expected behavior. Once confirmed, the program files were compressed into a ZIP archive for submission. This approach demonstrates practical software development techniques such as code reuse, modular programming, and debugging—essential skills for real-world programming tasks. By replacing a problematic code segment with a tested, functional equivalent, the program was made fully operational, illustrating an effective method of integrating existing code modules to enhance overall application robustness.
