GUI for Hangman Code Deletes File txt Contents but Doesn't Save Output into Text File Error

0

I am currently coding hangman with GUI using swing and awt. Currently I want to save the output into a text file. However, when I try to save contents in the text file, the code only deletes the contents of the text file but doesn't write anything in the text file. Also, if I don't include [throws FileNotFoundException] at the beginning of the method, [Tester()], the code also doesn't run. Does anyone have any insight to fix this issue? I am fairly new to java and I don't yet understand very complex commands and etc. If you can, please try to keep it simple.

My end goal is to save the letters already pressed (buttons on the gui) into outputString so that the next button press will output all instances of the letter being pressed as well as the letter that was pressed before.

What I want the code to do:
If I pressed the button E:

_e___ ____e E

If I pressed the button W after:

_e___ W____ E

What the code does:

If I pressed the button E:

_e___ ____ E

If I pressed the button W after:

_____ W_____ _

I am currently coding hangman with GUI using swing and awt. Currently I want to save the output into a text file. However, when I try to save contents in the text file, the code only deletes the contents of the text file but doesn't write anything in the text file. Also, if I don't include [throws FileNotFoundException] at the beginning of the method, [Tester()], the code also doesn't run. Does anyone have any insight to fix this issue? I am fairly new to java and I don't yet understand very complex commands and etc. If you can, please try to keep it simple.

My end goal is to save the letters already pressed (buttons on the gui) into outputString so that the next button press will output all instances of the letter being pressed as well as the letter that was pressed before.

What I want the code to do:
If I pressed the button E:

_e___ ____e E

If I pressed the button W after:

_e___ W____ E

What the code does:

If I pressed the button E:

_e___ ____ E

If I pressed the button W after:

_____ W_____ _
