Last week, we had the author of TDD for a Shopping Website LiveProject. Friday at 11am Ranch time, Steven Solomon will be hosting a live TDD session just for us. See for the agenda and registration link
Hi,i have a doubt about the difference between c and java i read the articles but they did not help me to understand(like definitions) i need more clarity about it is anyone suggest me how to get that stuff that is very clear and better to understand...???
C is not object oriented, it is a procedural language. C++ is a set of object-oriented extensions on to of C. Java is object-oriented. The basic syntax of Java come from C and C++.
All three (C, C++, Java) come with libraries of pre-written functions/objects. You can also get additional libraries for all three. But the types of functionality provided by each of those sets of libraries is vastly different (though there are overlaps).
In C/C++, you have to manage memory your self. You often have direct access to the hardware (as much as the OS will allow). And you can do incredibly strange and wonderful and often dangerous things with C/C++. In Java you are much more restricted, you can't get at memory or hardware directly (but there are often methods for doing some things), and Java itself relies on libraries written in C/C++ to access OS functions (even networking). Also, Java manages memory for you, including cleaning up unused objects and thus freeing memory.
C/C++ compiles into machine code directly processed by the CPU. Java gets compiled into intermediate opcodes which are initially interpreted by the JVM but ultimately compiled at runtime into machine code. A C/C++ program must be recompiled for every platform it will run on. A Java program can be run on any platform that has a JVM without any recompilation.
All three are similar enough that if you know one you should be able to write simple programs in any of the others. All three are different enough that you have to learn how to think in that language before you can really master it.
I think that covers the basics, but I'm sure I missed some.
