4.
class apples{
public static void main(String args[]){
System.out.println("hello world");
}
}

Here in this program what happened that I will show you later.I want to show you just "How to run a java program without a program editor or software".

Swift Programming Language:Here it is a new programming language for apple.In Swift,article is about Apple programming language.It is a multi-paradigm compiled programming language developed by apple for iiOS and OS X development.

This Swift programming language is built with the LLVM compiler included in Xcode 6 beta, and uses the Objective-C runtime, allowing Objective-C, Objective-C++ and Swift code to run within a single program.

Software

Software or Computer Software is known as computer programs.It is a such kind of thing that makes our life easier.Computer software related in the computer hardware,which is the physical component of computer.


At the lowest level, executable code consists of machine language instructions specific to an individual processor – typically a central processing unit (CPU).

Software is usually written in high-level programming languages that are easier and more efficient for humans to use (closer to natural language) than machine language.
Here a computer software can build with programs.There are many kinds of programming language.Such as C,C++,C#,JAVA.Python,Oracle,PHP etc.

C and C++ is the programming language which for the most beginning level.So that For learning programming language it is better to start by C.

I want to say that if you want to know about the programming language,then visit this site.
Now here it is the most popular language to learn. I think that if you know about the C language then all kind of programming language will easy to learn.
