Hi. Wonder if anyone can help me here.
Basically what i'm working on is a bit of code that reads an array from a file, sorts it, and then writes it back. It's not part of any bigger project, i'm just trying to understand how it all works
Reading from the file works fine, sorting the array works fine, but writing back to the file does not. It only outputs one element of the array, despite outputting the sorted array to the screen correctly. It is probably a silly mistake that i've made and can't spot it for looking.
What I don't get is, despite the code handling.. actually.. i think i just understood... It is re-writing the file everytime isn't it. Balls. There is only one element appearing because that is the last one to be written.. hmmm... help?

Code:
for (int i = 0; i < test.length; i++)
{
String[] tempRow = test[i];
for (int j = 0; j < tempRow.length; j++)
{
System.out.print(tempRow[j] + " | "); //debug screen output
try {
BufferedWriter out = new BufferedWriter(new FileWriter("c://java//output.txt"));
out.write(tempRow[j] + " | ");
out.close();
} catch (IOException e) { }
}
System.out.println(); // debug screen output
