I am totally new to java,please provide any solution for my problem

Welcome! Please read Announcements - What's Wrong With My Code?

You can do internet search to find a way on how to read from and write into a file. Then try to code it for yourself. Once you have the code, but some errors or bugs occurs you can ask here. Or even if you successfully made the program but have doubts if your coding is okay, you can also create a thread here to ask.

This is my complete program , I am getting error like

please help mw whats wrong in my code.

Please post your code correctly per the link provided by dicdic in post #2.
