I need a help in writing the java code to display the output in the following format,

Please help me in correcting this java file and print the output in the correct format.

I have 2 folders(Folder_1 and Folder_2) inside a folder(abcd). Inside the Folder_1, I have 2 files "File_1" and "FIle_2".

Inside "file_1", i have 7 lines of code liek Line_1, Line_2... Line_7...

I am finding the tag closing in many places. I need that to be closed when it finishes the Folder_1 only.

} 
}

Issue faced : the format is not proper which i am expeccting.

I think best way is to create a dom tree and persist it with pretty printing option turend on

Alternatively have a proper class created and use xstream to persist xml
