How is Java different than any other OOP language lke C plus plus?

Answer 1

There are many differences between Java and other programs, as there are also similarities: - managed code: java does not produce native code, but some byte code that will make it runnable in something called "virtual machine". The best thing about that: compile on windows and deploy that application on UNIX. - full object oriented -- even more than C++ where global variables are possible. Here, in java, everything must take place in an object - works on many operating systems. - a lot of technologies grouped in J2EE, that covers many the aspects of enterprise programming - servlets, jsp, ejb, jdbc to access the database, etc. The list is huge, I don't want to get in too much detail about that.

I guess it features some of the most mature technologies on the market.

Answer to: which programming language is more robust C sharp or Java?While I generally prefer "C" as a more robust language, I also consider anything that is released by Microsoft to be unreliable and likely to fail. Java is the product of Sun Microsystems, and has a very good reputation. While I'm not a Java programmer, I have heard nothing but good reports about Java. Answer to: why is Java more secure than other languagesJava is considered more secure than other languages for several reasons:

• The Java compiler catches more compile-time errors; other languages (like C++) will compile programs that produce unpredictable results.
• Java does not allocate direct pointers to memory. This makes it impossible to accidentally reference memory that belongs to other programs or the kernel.
• ... (can't think of anything else off the top of my head)

Answer to: what is the difference between .net javaThe Major Difference between .Net and Java is

1)Java is a purely Platform independent means the application that will work in any kind of Operating System.But .Net is platform independt software.

2).Net support to develop application in different languages and to develop application Rapidly. This feature is not exist in Java

Answer to why is Java more popular than CA long time ago, many people believed Java was slower than C because Java had to run through a virtual machine. Today however, Time and speed aren't really affected by the programming language or the used technology as much as affected by memory cards capacity and processors speed (Clock rate). Hench programmers and developers started looking for the most powerful yet easy to 'learn and work with' programming language. And there came Java with the multi-platform support, Object oriented methodology and other great capabilities and features.

On the other hand, General Purpose applications are still developed using C++ because it doesn't need any intermediate software to run.

and i think that java it's been improved everyday by the newest releases of the implementation of the virtual machine.

Answer 2

The advantages of the Java programming language are:

1. Write once, run anywhere 2. Security 3. Dynamic & Extensible programming 4. Internationalization 5. Performance 6. Programmer Efficiency

Answer 3

Java is object oriented like C++ but this programming language is not

platform dependent. It is platform independent. This is because it generates

byte code when you run your program not the exe file thats why it is platform

independent.

Answer 4

The Java platform differs from most other platforms in that it's a software-only platform that runs on top of other hardware-based platforms. The Java platform has two components: 1. The Java Virtual Machine (Java VM) 2. The Java Application Programming Interface (Java API)

Answer 5

Java is loosely based on C++ but has a much simpler object model. Java programs also run in a virtual machine which allow them to run on any platform that supports the virtual machine. The downside is that Java programs are many times slower than an equivalent C++ program would be. However, non-trivial C++ programs are not cross-platform compliant and must be compiled separately for each platform, which either requires a major re-write of the code or extensive use of preprocessor directives.

Answer 6

C, and C++, are compiled into "binaries" which target a specific operating system and CPU architecture. This means that those programs can not directly run on multiple operating systems. Windows programs will not run on Linux, nor will Linux programs run on Windows. The ability to run these programs on multiple operating systems is achieved through emulation or cross-compilation. It is usually said that such programs will run at least marginally faster than Java when running on their native platform, and will probably perform slower than Java when running through an emulation.

Java, in comparison, is compiled into "bytecode", which is then compiled by a Virtual Machine to provide the best performance. Java uses just one binary that will run on all platforms that support that version of Java, albeit it will run marginally slower than C or C++, and will likely not have the same "look and feel" as the rest of the operating system. The advantage, however, is that no special care must be taken to write a program that runs equally well in Windows and Linux (and Mac, etc), so long as the developers stay away from a few system-dependent features (usually code that is called "native"). Even using "native" code will still allow developers to write a core that runs the majority of logic in the Virtual Machine, and then use native code to access special system features.

In summary, Java runs on a number of platforms with a single compiled binary, while C++ requires a different compilation for each platform it is to run on.

Answer 7

The key reasons why Java is preferred to other programming languages are: 1. Write once, run anywhere 2. Security 3. Dynamic & Extensible programming 4. Internationalization 5. Performance 6. Programmer Efficiency

Answer 8

Java provide us magical bytes code and independence plate form.

Answer 9

Java is an object-oriented programming (OOP) language, which basically means that you can do more with it than you can do with a language that is not object-oriented.
