Downloading and installing JDK in windows

Download the JDK from the web URL:-


Since you’ll be learning how to develop Java programs, download JDK from the following website:
http://www.oracle.com/technetwork/java/javase/downloads/index.html


After selecting the Windows platform and clicking the Download button you’ll see a Login for Download
screen, which is optional: You can skip this step.

After the file is saved, start this executablen and the installation wizard will lead you through the process. Read and accept the license agreement and click the button Next. Note the item at the bottom of the left box

in Figure— it is an open-source database management system (DBMS) called Java DB. You’ll need JavaDB for comming time. A couple of minutes into the installation process you’ll see a pop-up window asking you where to install JRE. I’ll assume that you’ve accepted the default directory (c:\Program Files\Java\jre6), but you can select a different one. Shortly, you should see a message telling you that installation was successful. Click Finish. At the end of the installation process you’ll see a website suggesting you register the install. This step is optional.If you have previous versions of JDK installed on your computer, each of them will be sitting in its own directory, e.g., c:\Program Files\Java\jdk1.6.0_019. But for a sanity check, I always open a command line window and enter java –version at the command prompt. Figure 1-3 shows the confirmation that I really have JRE 1.6.0_19 (Java 6 is also referred to as Java 1.6).

Congratulations! Your JDK and JRE are installed.
