Something wrong in writing a new file

Question

Hello,
I'm new to Java and I seem to have trouble in writing a string to a file.
Here is the code:
void show_seat()
          try
               BufferedWriter tr=new BufferedWriter(new FileWriter("try.txt"));
               for(int i=0;i<5;i++)
                    for(int j=0;j<4;j++)
                         String t=fclass[i][j];
                         tr.write(t);
                         x.print(t);
                    x.println("");
          catch(IOException e)
               System.out.println("File Not found");
     }My array is perfect and it is printing out the correct output. But for some reason it just doesn't write it into the file.
Also could someone tell me how to close a file properly!!

Answer 1

You need to flush the writer. Close()ing it willdo
that. The close() call should be in a finallyblock.
Well I'm trying to close the file by saying
tr.close();
But is says it cannot be resolvedBecause you declared it inside the try block.
BufferedWriter br = null;
try {
   br = ...
   br.write or whatever
catch (...) {
  Note that just printing defeats the purpose of catching.
  You should handle it or not catch it in the first place.
  For a simple exercise like this it's okay though.
finally {
  if (br != null) {
    try {
      br.close();
    catch (Throwable th) {
      Here it's correct to do nothing at all or just log it.

And Also I haven't learnt about how to flush the
Buffer in class.Closing it will flush it.
