Try it Online Option

We have set up the Java Programming environment online, so that you can compile and execute all the available examples online. It gives you confidence in what you are reading and enables you to verify the programs with different options. Feel free to modify any example and execute it online.

Try the following example using our online compiler available at CodingGround

public class MyFirstJavaProgram {

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

For most of the examples given in this tutorial, you will find a Try it option in our website code sections at the top right corner that will take you to the online compiler. So just make use of it and enjoy your learning.

Local Environment Setup

JUnit is a framework for Java, so the very first requirement is to have JDK installed in your machine.

System Requirement

JDK 1.5 or above.
Memory No minimum requirement.
Disk Space No minimum requirement.
Operating System No minimum requirement.

Step 1: Verify Java Installation in Your Machine

First of all, open the console and execute a java command based on the operating system you are working on.

OS Task Command
Windows Open Command Console c:\> java -version
Linux Open Command Terminal $ java -version
Mac Open Terminal machine:< joseph$ java -version

Let's verify the output for all the operating systems −

OS Output
Windows

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

Linux

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode, sharing)

Mac

java version "1.6.0_21"

Java(TM) SE Runtime Environment (build 1.6.0_21-b07)

Java HotSpot(TM)64-Bit Server VM (build 17.0-b17, mixed mode, sharing)

If you do not have Java installed on your system, then download the Java Software Development Kit (SDK) from the following link http://www.oracle.com. We are assuming Java 1.6.0_21 as the installed version for this tutorial.

Step 2: Set JAVA Environment

Set the JAVA_HOME environment variable to point to the base directory location where Java is installed on your machine. For example.

OS Output
Windows Set the environment variable JAVA_HOME to C:\Program Files\Java\jdk1.6.0_21
Linux export JAVA_HOME = /usr/local/java-current
Mac export JAVA_HOME = /Library/Java/Home

Append Java compiler location to the System Path.

OS Output
Windows Append the string C:\Program Files\Java\jdk1.6.0_21\bin at the end of the system variable, Path.
Linux export PATH = $PATH:$JAVA_HOME/bin/
Mac not required

Verify Java installation using the command java -version as explained above.

Step 3: Download jsoup Archive

Download the latest version of jsoup jar file from Maven Repository. At the time of writing this tutorial, we have downloaded jsoup-1.8.3.jar and copied it into C:\>jsoup folder.

OS Archive name
Windows jsoup-1.8.3.jar
Linux jsoup-1.8.3.jar
Mac jsoup-1.8.3.jar

Step 4: Set jsoup Environment

Set the JSOUP_HOME environment variable to point to the base directory location where jsoup jar is stored on your machine. Let's assuming we've stored jsoup-1.8.3.jar in the JSOUP folder.

Sr.No OS & Description
1

Windows

Set the environment variable JSOUP_HOME to C:\JSOUP

2

Linux

export JSOUP_HOME = /usr/local/JSOUP

3

Mac

export JSOUP_HOME = /Library/JSOUP

Step 5: Set CLASSPATH Variable

Set the CLASSPATH environment variable to point to the JSOUP jar location.

Sr.No OS & Description
1

Windows

Set the environment variable CLASSPATH to %CLASSPATH%;%JSOUP_HOME%\jsoup-1.8.3.jar;.;

2

Linux

export CLASSPATH = $CLASSPATH:$JSOUP_HOME/jsoup-1.8.3.jar:.

3

Mac

export CLASSPATH = $CLASSPATH:$JSOUP_HOME/jsoup-1.8.3.jar:.
