Hello friend today easy tutorials is going to teach you a very simple program in JAVA. Yes today I am going to provide a tutorial about how to print hello world in JAVA. These days the JAVA is used in everywhere such as we are using the JAVA in our mobile phones, Music Players, Computers, and Cars etc. JAVA is programming language such as C and C++. If you have already known about the C and C++ programming language than it will not be such difficult to write any types of program in JAVA. Before starting the JAVA programming language let me tell you the required softwares to run JAVA; yes you need JDK to run program written in JAVA extension. JDK help you to compile and execute the JAVA code. Firstly you need to download the latest version of JDK from www.oracle.com and install into your computer. After the installation of JDK is completed than for your convenience copy the installed file of jdk1.7.0_03 (this is latest version of JDK in my system) from My Computer—-C:—Program Files—JAVA to C:. After the file is copied than rename it as jdk1.7 (according to your choice). You also need to create a folder as Javaclass in C:  so that you can save you all JAVA programming codes here. After these set up is done than start to write the codes in notepad or notepad++ editor. Here in order to print Hello World write the following code in Notepad or Notepad++ editor.

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
    }
}

After this code is written in Notepad or Notepad++ editor save it in javaclass folder which you have created before as file name HelloWorld.java. Here remember that you must give the file name whatever the letters is written after public class. Here I have written as public class HelloWorld so you must save the file as “HelloWorld.java”. The JAVA is case sensitive so you must look for it too. After the code is saved in javaclass folder then

• Open Command Prompt
• Type cd\ and press enter
• cd\jdk 1.7
• cd\bin
• javac
• javac c:\javaclass\HelloWorld.java

If you the code is error free  than it will display c:\jdk 1.7\bin> in your command prompt.

If you code is error free than type followings

• set classpath=c:\javaclass
• java HelloWorld and press enter.
• Prompt will execute Hello World.

Here you will see ‘DB_Name’,’putyourdbnamehere’; replace putyourdbnamehere to wordpress, usernamehere to root and yourpasswordhere to nothing (leave it blank deleting yourpasswordhere). Now save this file in new file name as wp-config.php.

Now in next step you need to transfer all extracted and edited to the root to run properly. In order to do this you need to know where the root directories is. After the installation of wampserver; by default your root directory will be in C: where you will find a folder called wamp and inside the wamp folder you will see a folder named as www folder.
