You have not asked any question yet. You just dumped some code in your post. And posting in "IM-speak" won't earn you much help either.

//button convert:

int valueFromTextField = Integer.parseInt(text);
// calculate conversion
// write to jTextFieldTo
// write one row of history to output streamStreams input & output you need open in CurrencyConvertor constructor , close if you exited from program.
Interesting is , what you have in "RATES.txt". You need properly read all info from RATES.txt.

Ask a question in a new thread if you need some help. Note that "help" doesn't mean giving you code to turn in for your assignment.
