Learn Java

Java is an concurrent, class-based, object-oriented and high-level programing language. The Java syntax is similar to C++ , but java is more strictly object oriented then C++.

It is intended to let application developer "write once, run anywhere" (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX.

• It is "WORA" means Write Once Run Anywhere. This concept of write once, run anywhere was used as a slogan to promote Java’s cross-platform abilities
• Platform independent
• Multithreaded :- With Java's multithreaded means a program can performs multiple tasks simultaneously.

What to do now after learning basics of C?

Well, I find that by basics of C you mean only writing some basic programs… But that is not learning C actually… You need to learn C in depth because C is the fundamental programming language that you need to learn if you aspire to code.

• I hope in basics you just covered the beginner level. Go for the Intermediate and Advanced Level now.


• Once you are confident, start solving questions from placement papers, competitive exam books (Made Easy and TMH are good choices).
• Code regularly in platforms like top coder, hacker rank, etc.


• Build projects from scratch without anyone’s help. Some good projects can be Library Management System, Snake Game, Quizzes, Department Store System, Tic-Tac-Toe, Telecom Billing Management System, Contact Management System, Medical Store Management System and even Bank Management System. (**C projects actually have no end, because kernel of almost all operating systems are written in C…)


• If you are satisfied with your knowledge of C, go for C++ followed by Java. (**Never study C# before Java… It’s dangerous… Most of Java concepts are just opposite of C#… Learning C# before Java is going to make you poor in Java… Go for Java first and then C#)
