Your code is very convoluted, but the reason for just the last line being written is clear - you open the file for each line you are about to output to it, and overwrite the previous contents of the file.

• You shouldn't open and close the file for each line. Open it once before the loop, and close it after the loop.

• If it did make sense to open and close the file multiple times, you should have opened the FileWriter in append mode (by using new FileWriter(FILENAME2,true)).
