Shift-Alt-J is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.
Invoking the shortcut on a class, method or field declaration will create a Javadoc template:
public int doAction(int i) {
return i;
}
Pressing Shift-Alt-J on the method declaration gives:
/**
* @param i
* @return
*/
public int doAction(int i) {
return i;
}
