Generate Javadoc in JDeveloper

1.First of all, we need add comments to the methods and classes.
for this, select a method and right click and select:Source–>Add Javadoc Comments
Other way is write /** and press Enter

2.Now, we can generate a Html Javadoc.
Select Project and in the top Menu select Build–>Javadoc for default the Html Javadoc will be created in  {folderProject}/javadoc but it can change in Project Properties–>Javadoc
