How to Download Java

Latest version of Java can be downloaded from Java Website.

Java Installation

There are no special requirements when installing Java.  Be sure that you have suitable permissions on your computer to install software. It can be installed like any other software (.exe).

Setting up the Environment Variables

After installing Java there are some environment variables that need to be set.

  • CLASSPATH : This environment variable points to the location of JDK home directory. It also contains the address of folder from where jars get loaded by ClassLoader (For more details of ClassLoader visit here)
  • JAVA_HOME : This environment variable will point to the location of Java home directory.

How to set environment variable in different platforms

Windows XP

To set up environment variables in Windows XP right click on the “My Computer” icon and select Properties. In the  Property window select the “ADVANCED”  tab and click on “ENVIRONMENT VARIABLES” . A window will appear were you can enter a new environment variable under System Variables by selecting New button.

Windows Vista / 7

To set up environment variables in Windows Vista / 7  right click  on “Computer” and select Properties. In  Property window select  “ADVANCED SYSTEM SETTINGS” and then select “ADVANCED” tab and click “ENVIRONMENT VARIABLES”. A window will appear were you can enter new environment variable under User/System Variables by selecting New button.

How to Check if Java is Installed

To check if your Java is installed properly open Command Prompt . To open command prompt write “CMD” in run command and hit enter. In the command prompt window write “java -version“.  If your Java is installed properly and all environment variables are configured correctly it will show the version of Java installed . Information reflected on the command prompt will be like

C:\Users\Jbt>java -version
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) Client VM (build 25.51-b03, mixed mode, sharing)

If there is any problem while installing or in setting up the environment variable, output on command prompt will be as shown below.

'java' is not recognized as an internal or external command,
operable program or batch file.

How to check if Java is up to date

To know if the Java installed on your system is up to date Click Here.

Our First Java Program

Though the popular first program to write in Java is” Hello World !! “,here we will write a program to print ” Hello JBT !! “. 🙂

Open any editor and write the below code.

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

Save the file with the name “FirstProgramme.java” in folder “c:\jbt”. Please note that name of the file should be same as the name given to public class(For more details regarding class file rules click here). Once the file is saved, open the command prompt and change the working directory to “c:\jbt”, where your file is saved. Write “javac FirstProgramme.java to compile the Java code as below.

C:\Users\JBT>cd C:JBT

C:JBT>javac FirstProgramme.java

C:JBT>

If the java file is compiled properly the compiler will create a class file for  the sourceJava. It will be saved in the same location as the source file. Since no package is declared in the given code the .class file will be created in the same folder location.

Notice the difference for Java files  using package declaration. Let’s create another Java file as below.

package com.jbt;

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

Save this file as “FirstProgrammeWithPackage.java” to “c:\jbt”. Now go to the command prompt and execute the below command.

javac -d . FirstProgrammeWithPackage.java

It will create the class file in a corresponding package(com.jbt).

Now that you know how to compile Java file with package and without package, the next step would be run these class files.

How to Run Java Application

Now that your  Java file is compiled we can execute the application using the “java” command as below.

Without Package

C:\JBT>java FirstProgramme
Hello JBT!

C:\JBT>

With Package

C:\JBT>java com.jbt.FirstProgrammeWithPackage
Hello JBT!

Or

C:\JBT>java com/jbt/FirstProgrammeWithPackage
Hello JBT!

 

Note*: The “java” command uses the class file name without its extension(.class).

With this we are done creating and running our very first Java application.

In the next section we will learn the difference between JDK and JRE.

      Hi,

      Thanks for your response. I will update the article asap. Meanwhile before you compile source code check if path of javac is in the class path. To check it execute the command “javac” in command prompt.
      If response is
      ‘javac’ is not recognized as an internal or external command,operable program or batch file.

      It means path is not set currectly. To set the pat go to enviornment variable section of computer properties.From there set the path of javac.”C:Program FilesJavajdk1.7.0_10bin”.
      Note this will be permanent and you don’t need to do the same thing of setting path again and again.

      Thanks Max again for pointing this.

      Yes, You can develop or run Java application in any major platform including Linux. You just need to download JDK specific for Linux. And you can start developing application. Click Here for different versions of JDK version for different platform.
      You can also download Eclipse for Linux from here

      Hi Garg,

      It seems like JDK is not installed in your system. Please install the same and check if javac is working or not(JDK and not JRE). If you have already installed then check if path for bin is already added in environment variable or not.

      It should resolve your problem.

      Thanks

    where i can see my jdk file.? in bin folder i seen jre file. when i can set the path it shows javac is not
    recoginsed as an internal or external command. whats the reason? please tell me

    Reply
    1. Vivekanand Gautam

      Hi Kalpana,

      You must download and install JDK from Oracle website and not JRE. Once you install JDK folder instide JDK should be like below

      lib
      jre
      include
      db
      bin

      If everything is installed properly you should see javac executable(javac.exe) file in bin folder.
      If it is not therer then you have not installed JDK properly. If you confirm that JDK is installed properly then add path till bin to classpath /path in enviornment variable. Then only windows will be able to recognise this command.

      Thanks

    my programm doesnt compile.i was install jdk properly.i also set path but still its give me an error like ‘javac’ is not recognize as an internal or external command,

    pls give suggestion

      Hi Sneha,

      Sorry for the late reply. As you can system is throwing an error of knowing command. In simple way you can say that your operating system(Windows) doesn’t know where this javac command(path).

      So to make OS understand you have to add path of javac in path in enviornment variable in My Computer.

      To know how to set path in windows you need to search on google or you can search article written by me.

      Hope this help.

      Thanks

      Hi Amriteya,

      If class file is create properly and java is not working then it might be the case that current folder is not in path(Enviornment variable) of your OS.
      Please check all you path, classpath in enviornment variable. It should contain . as . represent current folder in windows OS.

      For your reference you can check my path entries.

      .;%M2%;%JAVA_h%;C:Program FilesJavajre7lib

      Here i have added . so it will compile and run wihout any problem.

      You have to set the path variable for java..
      Right click on My Computer and select properties.
      Select advanced system settings.

      Click on environment variables tab.
      Now under user variables section , add a new variable with it’s path being the installation directory of java.

      Reply
    2. Steven grogan

      Try editing the Enviroment variables, make sure you include the semicolon before you write the path of where your JDK was installed, or it will not work. if you did install it in the same directory as the tutorial, your path should be:
      C:jdtbin

      and your path variable should look like (On the end of it):
      ;C:jdtbin

      if that doesn’t work, try making a folder in the jdt folder, that should work as long as you specify the directory.

      Hi Avi,

      You just need to understand eclipse have different build release for different languages.

      There is no specific version just pick the java specific build and it will work for Java.

      http://www.eclipse.org/downloads/

      Here you can see different build to download. Select only java specific to download for different platform(Windows/ Unix)

      Hope it help.

      Click on Environment Variables, under System 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 class as the value.
      Reopen Command prompt window, and run your java code

      There is no direct linking between C++ and Java. So yes you can learn java without knowing C++. Knowing C++ will help you in java, as some concepts are common but that will give you starting advantage but still you can learn java from scratch.

      Hi Giri,

      There is no direct answer to this question. It all depends on where you are coming from. If you have learned C++ and then i might say you can learn a bit about Java. But in the end 10 is not enough to learn any language. But still in indian companies you don’t need to be rocket scientist to work on any project. So just start learning java soon you will learn enough to work.
      Best of luck for your new project.

    I would suggest you to add the matter here which will be beneficial for the students/readers.

    Thanks again you this awesome work. Hope you will take my words into consideration.

      package is way of organizing java classes inside a project. You needs to have unique class name inside a package name. But class with same name can exist in different packages.

      Hi Prabhavathy,

      I really don’t know the answer of this question. Just knowing java will not solve all your problem. But it will help you definitely. And learning java is not difficult unless you have good teacher.

      I would like to share my real time experience here. I would say if you love programming go for it. Learning Java, gives you strong foundation for any IT professional line you desire. There are so many opportunities in IT like Business Analyst, Quality Assurance where one would expect to bring programming skills and Java is one among them. Within QA there are Automation programming tools like selenium. You can take this knowledge (Programming skills) and apply these skills in learning any other tool or building a Programming career (Entry level). Hope this helps!

    I accidentally landed on your page while I am googling for Java Tutorial for my nephew.
    I have gone over this blog. The Tutorial was been built with very good thought process.. I would say If one spends their time, they certainly end up with strong foundation level in JAVA which I feel many of the IT professionals certainly need.
