eclipse - How to build a Template like javadoc in jdt and cdt -

i trying incorporate feature similar javadoc in java , c/c++ editor. suppose type "abc" , press enter, should auto completed

     /*     * abcd     * xyz     * 1234     */ 

i have programmatically. ways can achieve this?

this link should add java code template programmatically

you can set context of template 'javadoc'

if not programmatically can go preferences->java->editor->templates. , create new template.

cheers, saurav
