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

    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
    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?

    try checking y[i].length - i guess its 0 - thus y[i][1] fails
