What must computers have in order for it to execute Java programs?

Answer 1

You need a really old computer. Preferably one from 1980 or so. It should have a small monitor. The monitor should take up a lot of deskspace but have a small screen area. Go for purity - so get yourself the earliest version of a borland command line compiler.

I personally find a keyboard is very useful, although you could use dip switches instead . Some geeks swear by a mouse, but there is the possibility that it is a passing fad. You can't be certain that mice are still going to be used in 10 years time.

It would be nice if your PC had a harddrive and a processor.

If you are thinking of learning C++, why not learn assembler first.

Answer 2

C++ imposes no software/hardware requirements in and of itself. C++ is simply a programming language and you can use any plain text editor to create C++ source files for any platform you desire. However, to create C++ projects you really need an IDE (integrated development environment) which will typically include a compiler, a linker and a debugger, and a wealth of project management tools, as well as dedicated code editors with a back-end syntax checker. Generally you will develop programs upon the platform you are targeting, however APIs (application programming interfaces) and SDKs (software development kits) can be used to target other platforms, including cellular phones and games consoles. In effect, the hardware/software requirements are dictated by the IDE within which you are developing your software and the platform for which you are targeting, not by C++ itself.

Answer 3

In order to run a C program, the source code must first be converted into native machine code. This is achieved using a C compiler and linker specific to the target machine. Note that it is the machine code program that executes, not the C program. Hence we call the machine code program the executable. If we modify the C program in any way, we must recompile the source code in order to create a new executable.

Answer 5

There is no minimum hardware requirement, other than that the platform complies with the compiler, and (or more correctly) vice versa.

Answer 6

For execute the java programs JVM(java virtual machine) is must necessary. JVM who takes the byte code of a program from system which is converted by the java compiler.

Answer 7

You cannot install a programming language, only a particular compiler. Chose one, and ask the provider about its requirements.

Answer 8

8 bits of RAM, and enough memory to hold the compiled program. While it's possible to compile an empty program into any sufficiently well-defined hardware, actually *doing* anything requires at least one variable, which the C standard requires be represented by a value with at least 8 bits.
