How To Install & Configure Java JDK On Your Computer?

How to enable your computer for java programming?

First,download Java Development Kit(JDK) form one of the following addresses-

http://download.cnet.com/Java-Development-Kit-64-Bit/3000-2218_4-75317068.html

http://java-development-kit-jdk.en.softonic.com/

Double click the downloaded file(in our example,it should be named as  jdk-7u6-windows-i586.exe) and follow the installation process,there will be two installations,one for the JDK, another is JRE(Java Runtime Environment).

After the installation,go to Command Prompt by pressing Windows Key+R. Type java -version and hit enter,it'll show interpreter's version. Then type javac -version and hit enter. If the javac command completed successfully then you don't have to follow the steps below. But,if you get an error like this-  'javac' is not recognized as an internal or external command,operable program or batch file ,then do the following-

Go to Start -> Control Panel -> System -> Advanced System Settings -> Environment Variables, select the system varable named "Path" and click the Edit button. Add the address of java's bin sub-directory at the end of the list in the Variable Value field(in our example C:\Program Files\Java\jdk1.7.0_06\bin) then click the ok button.

To test the environment open command prompt by pressing Windows Key+R.

Type java -version and hit enter to see interpreter's version number.

And type javac -version and hit enter to see compiler's version number.

Both the versions should match. If it matches,you're ready to do java programming!

Note: Other than java programming,if you install the jdk,you'll be able to run java-archives(i.e .jar files) on your computer! There are plenty of java applets(small applications) are available on the internet for free! Also java is needed for surfing various internet sites.

Nokia Pc Suite Not Detecting My 5233 Phone,Solved!

Hi there!

Few days ago,I formatted my pc and loaded Windows XP Professional Service Pack 2. After loading all softwares,and setting everything up,I connected my Nokia 5233 to my computer in Pc Suite Mode.

I was using Nokia Pc Suite 7.1.18.0. But windows could not detect my phone. I checked my phone, Menu > Settings > Connectivity > USB > Pc Suite Mode. Ask on Connection > No. That means setting is ok on phone. And there's a small USB symbol on the top right section of the screen. This indicates that the phone is recognising the USB connection. What might be the problem?

After doing a little research and googling,I found the solution! This is a driver related problem. You have to download the latest driver from this link-
http://europe.nokia.com/support/product-support/cable-drivers/driver-for-nokia-dke-2-dku-2-ca-42-ca-53-ca-70-ca-101

Download the driver,now go to Start > Control Panel > Add or remove programs > Find 'Nokia Connectevity Cable Driver' and uninstall it. Now close Control Panel and install the newly downloaded driver. If it asks for restart,click yes. After restart,connect the phone in Pc Suite Mode,it will detect the phone. Leave it for few minutes while Windows configures and installs the phone. Now you're ready to use it. Enjoy!
