Search and delete data to a Text file in GUI
Hi there!!! I'm a beginner in java programming and i need some help for doing this program.
The problem is making a file manipulation in GUI where u can add, search and delete to a text file. I'm actually done with adding data to a text file, my problem is how i can delete and search data to a text file. thank you for those who are willing to help me
Re: Search and delete data to a Text file in GUI
Since random access to data stored in a file is not easy or practical, one typically works on the data, in this case text, in memory. Load the data from the text file into memory and search the data, deleting, modifying etc. as needed. When done, write the result back to the file.

Hello.
Use JTextArea on your GUI component. Whenever you open/work with a file load the file contents into this text area.
Add TextListener to the text area. Whenever the text changed event takes place copy the contents back to the original file.
Coming to search, GregBrannon already gave the idea. Just cache the file contents and search.
