[code try { String file=jTextField12.getText(); DataOutput f=new DataOutputStream(new FileOutputStream(file+".txt")); f.writeBytes("Answers"); for (int output=0; output<count1; output++) f.writeBytes(count1+"="+answer1[count1]); } catch (Exception e) { String msg=e.toString (); } // TODO add your handling code here: } ] For some reason this program isn't working |

Can you be more specific? What exactly do you mean when you say "For some reason it doesn't work"? Does the program give an error message? Is it not outputting anything at all, or is it just outputting wrong? It would probably help to see what the problem is if you gave a full program, instead of a chunk of code that can't be run on its own. |

Yup, I agree. For all we know your program could just have some stupid mistake like the method not throwing an IOException or forgeting to import a class or... (u know wut I mean) It could help a lot if you can copy and paste your code from top to bottom of the whole file. |

You have to close IO streams before it actually writes anything to file in java. |

Alternately, you can call .flush() on them to force them to write - this is actually done as part of the close() operation. |
