They don't.
Java does not require header files like C/C++.
C, C++ and Java are cross-platform languages. NET is for Windows-only.
C, C++, Java, C-Sharp
C++, C#, c+ and java
java is similar to c/c++,easy to learn if you have some programming experience. and also the developers omitted the concepts of pointers(which are very difficult) in java When java is developed,developers want it to be simple because it has to be work on electronic devices.Where less memory is available.
Java is not similar to C. Java is, however, similar to C++. Both C++ and Java are object orientated programming languages (OOPL's).
Java is object oriented, C is not...
Java does not require header files like C/C++.
C can be faster than C++ programs, and definitely faster than Java, since Java is primarily interpreted. C is also somewhat less rigid in definitions as well, not as tightly structured as either C++ or Java can be.
Java is considerably easier than C++.
None, as C was made prior to Java.

No. You can learn Java first if you want. However, from a language perspective, C++ and Java are nearly identical1, and C is the predecessor of C++, so some people feel that the proper sequence is C, then C++, then Java. It is entirely up to you. ----------------------------------------------------------------------------- 1Nearly identical, that is, from a language perspective only. The environment and libraries are vastly different between C++ and Java.
java language moreover solve the problems witch is encounter in c and c++ that s why we use the java language...
