Question

Day in and day out, you probably depend on many different sorts of complex technological tools and innovations. Luckily, the modern world has embraced some sense of user-focused design in many of its products, so you should not need an engineering degree to operate a microwave oven or create a spreadsheet on your laptop. The most popular technology just works and does not require you to toil over hundreds of densely packed pages of a user manual. Imagine sitting comfortably at home. You call a friend on your cell phone. A lot of technology is at work behind the scenes in those few seconds before your friend answers. This hidden machinery allows you and your friend to speak nearly instantly no matter where either of you are on the planet. Youand most cell phone userscan remain blissfully unaware of everything that happens to process a mobile call. Similarly, programmers need not know the ins and outs of every single method or class they use. For example, you have used ArrayList classes in this course, but understand only how to create a collection of elements using an ArrayList and how to access the class within the java.util package. Just like the cell phone user, you are most familiar with the interface of the tool, rather than its inner workings. If you found another Java class that allowed you to create classes, you could adopt it quickly, much like you could change cell phone carriers. You count on your tools to make your job easier, and you are not sweating the details. When you adopt classes from another user or library, and you are completely oblivious to what is happening behind the scenes, you are definitely working with a loosely coupled program. Users of such programs often remark, I am not sure how it works, but it works. They do not need to tear the code of the application apart and learn how it accomplishes its task, and this is ideal. A loosely coupled program does not depend on a specific context to run correctly. These applications can be swapped without affecting a program; they are wholly self-contained, and can easily be scooped out of an application without leaving carnage in their wake.

Explanation / Answer

Yes, what you said is absolutely correct.The programmer need not to know the inner process but should very clear about the functionality.If you want to Develop a new programming language then you should know how to process the methods and classes.At present everyone are developing in existing languages only.Its better know deeply the inner functioning if you are serious about developing your own language and you want to do more.
