I see a large list of programming languages here. What is the reason of using JVM and what are other options for a new programming language?
byte code can be run on any system with a JVM. If you are creating a new language, or porting an old one, all you need do is generate byte code (much simpler than optimal code for a real machine) and you are done.
Note: many of the JVM ports are faster if you use a JVM as well as much more work has gone into optimising the native code.

I am a sophomore in college currently learning core java basics. Java is said to be an object oriented language but I don't see how the use of OOPS benefits the code bases especially the long ones in the industry.
SO I tried mugging the theory without understanding the applications behind it and it was kind of difficult so I don't know what to do now

I am working on a project which uses text files (.txt) for input, reading them line by line but this files can go as large as 1 terabytes. I know some languages/technologies which I used for similar problems, those are Java, Bash, Awk, and Python. But I don't know which one can work with such large file, and what kind on tricks and tweaks will be needed.
As long as you process your file line by line and you assemble some statistics, it doesn't really matter what tool you choose.
Java has some advantage in terms of speed, compared to scripting languages, but in the end it will be a difference only by a constant factor. What matters the most is the algorithm that you use to process the file.

I want to learn C++, I already program in Java.
What are the aspects of C++ for which Java programmer should keep an eye on.
(I moving from java to C++ for game programming.)
The major thing you're going to have to watch out for is memory management. Learnt about it in C++ but do your best to use classes like shared_ptr wherever possible.

I have a textbook, "5th Edition Lewis and Loftus Java Software Solutions: Foundations of Program Design". The edition is from 2007. Can I use this to learn java, or is too outdated to be worth my time?
Java is always changing but not be very much. I have used that book for the newest version of java and some stuff doesn't work but for the most part you should be good. If something doesn't work in that book then simple just go onto google or some other search engine and check out the new way.
Best of Luck,
Dev

I have tried ProGuard many times and spent a lot of time on configuring it to no avail in the past year or so. It seems to have some inherent limitations related to pre-compiled third-party libraries as explained in its document. ProGuard document nicely provides a long list of alternatives. Instead of trying them one by one, I am here to see if any could share successful experiences with some of them. I only need something to obfuscate java code. Code shrinking and optimization are nice to have, but not required.
