File output in JAVA (not C++ sorry to offend;))

[neil_w_84]

Hey sorry know this is strictly a c/c++ board but you guys seem helpfull so maybe u can help with some java to, I have the following code

public static void outputFile(double[][] y)
	{
		// Declare output file
		File file = new File("output.txt");

		try{
			// Declare file output stream
			FileWriter fos = new FileWriter(file);

			for(int i = 0; i < y.length; i++)
			{
				char yc = (char)y[i][1];
				fos.write(yc);
			}
			// Close the file
			fos.close();
		   }
		catch(IOException ex)
		{
			System.out.println(ex.getMessage());
		}

	}

and im getting an array index out of bounds excpetion. Cant figure out why tho as the for loop is for the length of the array and i write one element of the array each loop iteration (or so i believe), any ideas?
