Most of your errors are in JavaApplication62 class. Ive corrected them to get the desired output you want. There are still many problems with all your classes. I’ll Leave that up to you to rectify.
Look to the comments for the corrections.

Also I’ve not improved your indentation. You should look at that also.
This will give you the output you mentioned in the question. But I think you should refactor a lot of your code altogether.
