Hello geeks,here is a short post on how to install JDK7U40 in your Windows 7 machine.
Download the java software here (http://www.oracle.com/technetwork/java/javase/downloads/index.html) bearing in mind the bits in your machine. ie is it 32 or 64 bits,
If you are having a 32 bit machine,
install ‘jdk……86’ notation,if you are using 64 bits use the ‘jdk….x64’ notation.
After download,install -run the software in your machine.
When installed,Go to your windows directory (i presuppose you are using C:\ drive).Locate java and open the JDK folder,as below;
Copy the path.
Then go to our computer system Environment settings;
Create a variable JAVA_HOME and paste the path on the value field.
Edit the System variables ‘path’,append this after placing a semi-colon(;)- “%JAVA_HOME%\bin”.
Apply and save the settings.
To test go to cmd prompt type- ‘javac’
More of it ….just Google!
