But, in case you want the same behavior for Java’s core classes too, you can have it by attaching the Java source with the Eclipse IDE. Once you attach the source, thereafter when you Ctrl+Click any Java class names (String for example), Eclipse will open the source code of that class.
To attach the Java source code with Eclipse,
- When you install the JDK, you must have selected the option to install the Java source files too. This will copy the src.zip file in the installation directory.
- In Eclipse, go to Window -> Preferences -> Java -> Installed JREs -> Add and choose the JDK you have in your system.
- Eclipse will now list the JARs found in the dialog box. There, select the rt.jar and choose Source Attachment. By default, this will be pointing to the correct src.zip. If not, choose the src.zip file which you have in your java installation directory.
- Similarly, if you have the javadoc downloaded in your machine, you can configure that too in this dialog box.
Done! Here after, for all the projects for which you are using the above JDK, you’ll be able to browse the Java’s source code just like how you browse your own code.
Bulletproof Java Code: A Practical Strategy for Developing Functional, Reliable, and Secure Java Code
Use Java? If you do, you know that Java software can be used to drive application logic of Web services or Web applications. Perhaps you use it for desktop applications? Or, embedded devices? Whatever your use of Java code, functional errors are the enemy!
To combat this enemy, your team might already perform functional testing. Even so, you're taking significant risks if you have not yet implemented a comprehensive team-wide quality management strategy. Such a strategy alleviates reliability, security, and performance problems to ensure that your code is free of functionality errors.Read this article to learn about this simple four-step strategy that is proven to make Java code more reliable, more secure, and easier to maintain.
