In Previous post we Learn History of C. In this Lesson we learn Features of C language.
C is widely used computer programming language. We can use C for different purpose. It provides lot features some are given below.

Simple
Machine Independent or Portable.
Mid-level programming language.
structured programming language.

History of C

ekambharam All Tags , C

There is a similarity between human actions and the way a computer various functions.Nicholas wirth the inventor of computer language -Pascal used to say "A program is equal to algorithm + data.
We perform hundred of activities during a day. An activity could be anything from brushing teeth to making tea and from going to work having dinner. There are two ways to describe in detail any of these activities.
1. By describing Step-by-Step process is called as algorithm.
2.By representing the various steps in the form of diagram is called Flowchart.

History of C

C programming language was developed in 1972 by Dennis Ritchie at bell laboratories of AT&T(American Telephone & Telegraph),located in U.S.A.
Dennis Ritchie is known as the Father of the c language.
It was developed to overcome the problems of previous languages such as B,BCPL etc.
Intially c language was developed to be used in UNIX Operating System. It inherits many features of previous languages such as B and BCPL. The Unix operating system, the C compiler , and essentially all unix programs have been written in C.C has now became a widely used professional language for various reasons.

Easy to learn
Structured language.
It produces efficient programs.
It can handle Low-level activities.
It can be compiled on variety of computer platforms.

Let c the programming languages that were developed before c language.

Java Basics

Basic java Syntax

About java programs,it is very important to keep in mind the following points.

Case Sensitivity: Java is case sensitive, which means identifier Hello and hello would have different meaning in Java.
Class Names:For all class names the first letter should be in Upper Case.

if several words are used to form a name of the class,each inner word's first letter should be Upper Case.
Example class MyFirstJavaClass.

Method Names: All Method names should start with a Lower Case letter.

If several words are used to form the name of the method,then each inner word's first letter should be in Upper Case.
Example public void myMethodName()

Program File Name: Name of the program file should exactly match the class name.

when saving the file,you should save it the class name(Remember Java is case sensitive and append.'.Java' to the end of the name(if the file name and the class name do not match your program will not complie)
Example:Assume 'MyFirstJavaProgram'is the class name.Then the file should be saved as MyFirstJavaProgram.java

public static void main(Stringargs[]) : Java program processing starts from the main() method which is mandatory part of every Java program.

Hello World Example

class HelloWorld

{

public static void main(String args[])

{

System.out.println("Hello world");

}

If all goes well you see the following output.

Hello world

Explanation:

All code is contained within a class,in this case HelloWorld.
class keyword is used to declare a class in java.
public keyword is an access modifier which represents visibility,means visible to all.
The file name must match the class name and have a .java extension, for example: HelloWorld.java.
All executable statements are contained within a method,in this case named main();
Use System.out.println() to print text to the terminal.

Java Setup

ekambharam All Tags , Java

Installing java?

you need to download java based on your operating system.
you can download java from http://www.oracle.com.technetwork/java/javase/downloads/index.html

Various editions of Java:

Java SE : stands for Java edition and is normally for developing desktop applications,forms the core.base API.
Java EE : stands for java enterprise edition for applications which run on servers,for example websites.
Java ME : stands for java micro(mobile)edition for applications which run on resource constrained devices(small scale applications) like Cell phones,for example games.

Every Java edition consists of two elements : JRE and JDK:

JRE: Java Runtime Environment. it is basically the java Virtual Machine where your java programs run on.It also includes browser plugins for Applet execution.
JDK: it's the full featured software Development kit for Java,including JRE and the compilers and tools (like JavaDoc,and Java Debuger)to create and compile programs.

Usually, when you only care about running Java programs on your browser or computer you will only install JRE. It's all you need. On the other hand, if you are planning to do some Java programming, you will also need JDK.

if you are a beginner ot you simply want to learn Java you can go ahed and download the JDK(Java Development Kit) for the Java SE edition. Simply download and install the exe file by following the instructions.

Setting Path variable

The PATH is the system or user variable that your operating system uses to locate needed executable from the command line or Terminal window.
the PATH system or user variable can be set using System Utility in control panel on windows, or in your shell's startup file on Linux and Solaris.

In simple words PATH helps the operating System to find where Java is installed.

Note: you need to copy the location of the bin folder of the Java installation directory in the PATH's Value field.

Example for Windows:

\ProgramFiles\Java\Jdk-176\bin;

Windows 8:

Drag the mouse pointer to the right bottom corner of the screen.
Click on the Search icon and type:Control Panel.
Click on->Control Panel ->System->Advanced
Click on Environment Variables under User variables, find PATH, and click on it.
In the Edit windows,modify PATH by adding the location of the class to the value for PATH.if you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the java bin folder as the value.
close the window.
reopen command prompt window,and run your java code,

Windows 7:

Select Computer from the Start menu
Choose System Properties from the context menu.
Click Advanced System settings > Advance tab.
Click on Environment Variables, under User Variables,find PATH , and click on it.
In the Edit windows,modify PATH by adding the location of the class to the value for the class to the value for PATH. If you do not have the item PATH,you may select to add a new variable and add PATH as the name and the location of the java bin folder as the value.
Re open Command prompt window , and run your java code.

Windows XP:

Start-> Control Panel ->System->Advanced
Click on Environment Variables,under User Variables,find PATH, and click on it.
In the Edit windows,modify OATH by adding the location of the class to the value for the class to the value for PATH.If you do not have the item PATH,you may select to add a new variable and add PATH as the name and the location of the Java bin folder as the value.
Re open command prompt window, and run your java code.

Compiling and Execution:

Create a temporary folder C:\mywork. Using Notepad or another text editor, create a small java file HelloWorld.java as shown in the HelloWorld example in the HelloWorld chapter.
Save your files as HelloWorld.java in C:\mywork. To make sure your file name is HelloWorld.java(not HelloWorld.java.txt),first choose "Save as File type:| All files, then type in the File Name HelloWorld.java.
Run Command Prompt(found under All Programs/Accessories in the Start menu).

Type:

1:C:cd\mywork

This makes C:\mywork the current directory

2: C:\mywork>;dir

This displays the directory contents.You should see HelloWorld.java among the files.

3 C:\mywork>javac HelloWorld.java

This runs java.exe,the compiler.You should see nothing but the next system prompt..

4: C:\mywork>;dir : javac has created the HelloWorld.class file.You should see HelloWorld.java and HelloWorld.class among the files.

5: C:\mywork>java HelloWorld

This Runs the java interpreter You should see the program Out put: Hello, world !.
