Instructions for downloading and installing Java Documentation
Sun Microsystems, the company where the Java language was invented, provides free documentation that describes the Java Development Kit as well as all the standard classes that form the Java class library. This page helps you to get the documation and install it locally on your own computer. Alternatively, you can use the documentation that is available on Sun Java pages on the web.Because you are unlikely to need the JDK documentation at the beginning of your studies, you can postpone this installation if you are beginning your studies.
The documentation is called J2SE 5.0 Documentation on Sun web pages. The documentation files are stored in a single .zip file named jdk-1_5_0-doc.zip. You should download this file from Sun Microsystems, and then unzip or unbundle the file in your own computer.
Before you go to the pages of Sun Microsystems, you should have a folder (directory) on your computer into which you download the .zip file, and into which you unzip the documentation. I'm supposing here that you create a folder named D:\jdkdoc for this purpose.
To get the jdk-1_5_0-doc.zip file from Sun, you should go with your Internet browser to the address
http://java.sun.com/j2se/1.5.0/download.jspwhere you can find a section with title J2SE 5.0 Documentation. By clicking the Download button in that section, you can get the .zip file. Please, study also the instructions on the Sun pages. After you have pressed the Download button, you need to accept a License Agreement before the download operation can begin. You will be asked to specify a folder into which the .zip file will be saved on your computer, and you should write there the D:\jdkdoc folder. As the size of the .zip file is more than 40 megabytes, the downloading process may take some time.When the file jdk-1_5_0-doc.zip is in the D:\jdkdoc folder, you can unzip it very easily if you are using the Windows XP operating system. In Windows XP unzipping can be done by just clicking the file’s icon. You should thus select My Computer > Local Disk D: > jdkdoc > jdk-1_5_0-doc.zip. In the unzipping process it is important that you select Extract all files, and I recommend that you extract the files to the folder D:\jdkdoc. The unzipping process can take a while as thousands of files will be extracted from the .zip file.
You can use your Internet browser to read the JDK documentation that you have installed. If you use the Microsoft Internet Explorer, you should select File > Open... and then press the Browse... button. After you have pressed the Browse... button, you select Local Disk D: > jdkdoc > docs > index.html, and then you have to press the OK button. After this you can use the documentation in the same way as it is used at the server of Sun Microsystems. If you use the Mozilla Firefox browser, you should begin the above activities by selecting File > Open File.... If you want to see the Java API specification in the local documentation, you have to select Local Disk D: > jdkdoc > docs > api > index.html.
