Hi All,
I want to develop a new java file creation wizard which will create a new java file in the workspace using a predeclared template.

Please guide me.
Any code snippet or similar thread link will be most useful for me.

Thanks and regards

Hi,

Creating a brand new plug-in for that may be overkill. The Eclipse Java Development Tools already let you change the code generated while creating a new class. I've explained more about this on my blog (section 3.10) as part of a collection of articles on the JDT. You just need to configure the code templates for a new file in the properties of your project. You can then define, for example, a copyright header that should be generated on top of all your Java files. This template will be used for ll newly created classes in the project.

Now if you really want to create a wizard, you should have a look at Lars' tutorial.

Regards,

It would be nice to have a possibility to configure different Java class templates for certain "types" of classes.

F.e. when I create a new class that extends another specific class, i want to populate this new class with specific code template.

I would then hit "Create new class", then pop-up opens, I enter whch class i want to extend, new class is created with populated code template.

Or even better a possibility to define a new "Create My Specific Class" key shortcut. After hitting the key, the class would be created automatically.

Have you looked at the Java->Editor->Templates feature? This allows you to define code snippets that will can be inserted using content assist (Ctrl-Space). Type the name of the template in your source file and hit Ctrl-Space. You will be given the template as an option. You can define variables that correspond to class name, method name, etc. This would allow you to create a class and then use content assist to fill in the details specific to the class.
