Sometimes it gets really difficult and time consuming to add javadoc manually (when you do not want to add any specific information).
In order to do that there is an easy way in Eclipse IDE !!!!
1. Go to Eclipse market place and download JAutoDoc.
2. Once you download JAutoDoc, you just need to go to the file where you need to add javadocs and press Ctrl + A and Ctrl + Alt +J.
Tada.... the javadocs will be added to your file, you can go ahead and change or add if you think any extra information needs to be added.
NOTE : Don't forget to remove a TODO statement in the starting of your file which also gets generated.
