Download Eclipse For Java Programming

I’m beginning a new Java tutorial using Eclipse as my IDE. Every time I have used Eclipse in the past there have been installation problems so, I’ll try to fix that issue here.

I use Eclipse because in my opinion it is the best free IDE available.

Also note that I’ll provide Java 1.7 installation steps for PCs, but Java 1.6 & 1.7 steps for MACs. The reason why I’m doing that is because Java 1.7 isn’t quite ready yet for Eclipse on MACs.

Don’t worry, there isn’t that much of a difference between Java 1.6 and 1.7. At least for a beginner tutorial.

Checking Your Version of Java

Java 1.6 has been around since December 2006, so chances are you already have it installed on your computer. To find out type the following in either your Terminal (MACs), or Command Line (PCs) java -version

When you do you’ll probably see the following:

• Execute Eclipse and then click on Elipse and Preferences in the top menu
• Expand the list item named Java and click Installed JREs
• Click the Add… button
• Java 1.6 should be set as the default
• If not select Standard VM in the JRE Popup Window
• Type /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home into JRE home
• Type Java1.6 as the name
• Click Finish

• Execute Eclipse and then click on Windows and Preferences in the top menu
• Expand the list item named Java and click the Compiler option (Don’t Expand it)
• Check if Compiler Compliance Level is set to 1.7
• If it isn’t change it to 1.7 in the dropdown
• Click on Installed JREs and if you see jre6 as checked you’re done
• If jre6 isn’t checked click the Add… button
• Select Standard VM in the JRE Popup Window
• Under Directory select the home directory for JRE 1.7 (See Above)
• Click Finish

1.

7. May I please request your kind help with installing Eclipse on Ubuntu 12.10 32-bit. I resorted to a Linux distro because my PC repeatedly chrashed under Windows XP Home Edition. I am most grateful for your kind help and advice.

8. Thank you very much for your most kind help with the Eclipse download. Your instructions have worked well giving me the much needed chance to put in some practise. I am practising with your very helpful code from Tutorials 1, 2, and 3. Sometimes Eclipse detects dead code, though it compiles and runs as expected. Thank you once again for your highly considerate Java Tutorials anlong with your continual help.
   Good wishes to you and best regards, too.

9. Hi Derek, First of all thanks a lot for all the great Videos and articles, Your explanations are crisp, clear and to the point.. Keep doing the great work.. Now my question is – I’m an professional .NET developer and planning to do some unofficial projects in JAVA, Android and IOS. Am also planning to make a switch from PC to MAC for my JAVA projects, Am planning to buy a MAC Book Pro, since i’m new to MAC i feel difficult to settle into MAC configuraiton..What do you think is the ideal configuration for a Developers MAC Book pro? Eventually i may also start using it for professional and consultation purpose

Installing Java Standard Edition 8
Eclipse Installation

You have access to lab machines that have these tools (or similar ones) installed, but many of you may want to install it on your own machines. These instructions are for those running Windows. Typically, Mac are supplied with a pre-installed version of Java; so if you have a Mac, you'll need to make sure that your machine has Java SE 8 pre-installed.

Eclipse Ide For Java Developers

Installing Java Standard Edition 8

In order to compile and run your Java programs, the Java SE Development Kit (JDK) must be available on your computer. If a recent version (i.e.: Java 8) is not already on your computer, you will need to download it from the Oracle site and install it. Please follow these steps.

• If you have previous installs of Java's JREs or JDKs, uninstall them using Windows Add/Remove Programs.
• Determine whether your computer is running the 32-bit version or the 64-bit version of the Operating System as follows:
  • Windows Vista: Click onStart>Control Panel>System and Maintenance >System
  • Windows 7: Click on Start>Control Panel/System and Security/System/View Amount of RAM and processor speed
  Search for System type to determine if your computer isrunning either the 64-bit or the 32-bit version of Windows.
• Once that has been determined, select the appropriate version of the JDK to download from Oracle. Select Windows x64, if your computer is running the 64-bit version, and Windows x86 (i586) for the 32-bit version.
• Once you have downloaded the file, run the executable. The install should progress like most program installs. You need to remember where it installs the SDK. In Windows, this is typically C:Program FilesJavajdk1.7.0_05 (the numbers will vary, depending on which update is downloaded).

Setting the PATH Environment Variable

Now you are ready to adjust some system settings so that Windows knows where to look when you try to use the java compiler as well as the run time environment. To accomplish this in Windows, you modify an'environment variable' called 'PATH'.

• To set the path permanently, choose Start>Control Panel>System and Security>System>Advanced System Settings. Windows 7 may prompt you for an admin password or pop up a warning window. Enter the admin password and click OK. You will have access to the System Properties Settings.
• Click on the Advanced Tab
• Click on the Environment Variables button. Look for 'path' in the system variables. and click on the Edit button.
• Click on the Variable value textbox, move to the end of the path, and type a semicolon followed byC:Program Filesjavajdk1.7.0_05bin (note: if you downloaded a different version of Java JDK or installed it in a different location, then you'll need to input the correct path to Java's bin folder so Windows can locate the installed Java programs). Be careful not to erase the other information in the PATH variable.
• Finally click OK.

• To set the path permanently, choose Start>Control Panel>System and Maintenance >System Properties. Vista may prompt you for an admin password or pop up a warning window. Enter the admin password and click OK. You will have access to the System Properties Settings.
• Select the Advanced System Settings, click on the Advanced tab and then on the Environment Variablesbutton.
• Look for 'PATH' in the system variables. and click on the Edit button.
• Click on the Variable value textbox, move to the end of the path, and type a semicolon followed by C:Program Filesjavajdk1.7.0_05bin (note: if you downloaded a different version of Java JDK or installed it in a different location, then you'll need to input the correct path to Java's bin folder so Windows can locate the installed Java programs). Be careful not to erase the other information in the PATH variable.

• Finally click OK

Now, we should test to see if it was installed correctly. In Windows, you'll want to run the cmd command or find the Command Prompt option in Accessories. Run the following command:

> javac -version
javac 1.7.0_05

> java -version
java version '1.7.0_05'
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

If you see similar output for the two commands shown above (the numbers should match the version you just installed), then you have installed Java correctly.

You should be able to use the programs located in the bin (binary) folder of your Java folder in order to compile and run your Java programs. You can do this in two ways through the use of a basic text editor and the command line or by using an Integrated Development Environment (IDE). First we show how to do it the old fashioned way before we move on to the IDE approach.
