Programming Environment is not a programming language element, it is a setup for developing programs,
Prerequisites to Write & Execute Software programs,
(OS, Editor, Compiler, Debugger)
1. Operating System installed in a Computer
2. Editor for writing the code
3. Compiler / Interpreter to convert the code
4. Debugger
Nowadays, IDEs (Integrated development Environments) are available to write & execute programs, IDE (ex: Eclipse IDE or PyCharm) is a platform to write, compile, debug, and run software programs, in addition IDE provides Syntax guidance, Context help, Integration with other software etc,
In case of Programming languages like C/C++/Java, there are three primary steps,
1. Write a Program
2. Compile the Program
3. Run / Execute the Program
Debug the Program (if required)
Again Run the Program
In case of Scripting languages like VBScript, JavaScript, Perl, Python etc, there are two primary steps,
1. Write a Program
2. Run / Execute the Program
Debug the Program (if required)
Again Run the Program
Note: Scripting languages interpret while running…
I will discuss you that how to setup programming environment for three different programming languages,
1. Java
To setup Java Development/Programming Environment,
Step1: Choose Operating System (Java supports various operating environment like MS Windows, Linux, Solaris and Mac…)
Step2: Download your operating system compatible Java Software from oracle.com (Ex: My OS is MS Windows 10 – 64 bit, so need to download my os compatible software)
Step3: Install the Software
Step4: Setup Java Environment variable
Step5: Write a Java program in Notepad like editor
Step6: Compile the program in the command console, and execute it…
* Instead of Step5 and Step6, use Eclipse IDE,
Download Eclipse ide & extract, Launch Eclipse IDE, and write & execute Java programs

2. Python
To setup Python Development/Programming Environment,
Step1: Choose Operating System (Python supports various operating environment like MS Windows, Linux, and Mac…)
Step2: Download your operating system compatible Java Software from python.org (Ex: My OS is MS Windows 10 – 64 bit, so need to download my os compatible software)
Step3: Install Python Software
Step4: Write Python program in python shell
Step5: You can run Python programs using either Scripting mode or File mode
* Or instead of Step4 and Step5, use PyCharm like IDE,
Download PyCharm ide, Install PyCharm, Launch pyCharm, and write & execute Python programs
3) VBScript
VBScript Environment is very simple, if you are using MS Windows Operating system, then it is built-in
Step1: Write VBScript program in Notepad and save as .vbs file
Step2: Run/Execute the Program
Note: VBScript is a light weight language, it interpretes while running the program
* Or Use “VbsEdit”
Step1: Download VbsEdit
Step2: Write VBScript Program in Vbsedit
Step3: Run/Execute the Program
Final, if we use any programming environment to write programs, then programs are stored in the harddisk.
We use group of similar programs to develop software applications.
Editors or text editors are software programs that enable the user to create and edit text files.
Notepad is the common editor used on Windows OS and viis the editor on UNIX OS.
A compiler is a software program that transforms high-level source code that is written by a developer in a high-level programming language into a low level object code (binary code) in machine language, which can be understood by the processor.
A debugger program is one that allows the user to view another program line by line. This allows the user to identify incorrect code and find out how a program flows.
