Writing String and Double values stored in Array to a file using BufferWriter

I have a simple question regarding how to write my object array data into a file Using a buffered writer, I have had no joy and I need some help please.

Please excuse my lack of knowledge I have only just started learning Java.

 Object[][] data  = {
                          {"dd/mm/yyyy", new Double(5), new Boolean(false), 
                          {"21/12/2013",  new Double(5), new Boolean(false)};
                开发者_运维知识库    }

   String    sDividendDate1       =   (String)data[0][0];
   Double    dDividend1           =   (Double)data[0][1];


try
 {
       FileWriter file = new FileWriter(NewCodeFile);
       BufferedWriter buffer = new BufferedWriter(file);
       buffer.write(sDividendDate1);
       buffer.newLine();
       **buffer.write(sDividend1);  /*This is where the compiler does not like 
       [I think it is because I am trying to write a double variable into a char 
       text buffer?]**/
}

How do I write the double value stored in dDividend1 in the same file after I have written sDividendDate1 into the same file. Any help is always greatly appreciated.

Many thanks

Kind Regards Stephen

Try String.valueOf(sDividend1)or Double.toString(...).

You might also want to check java.text.NumberFormat.

Stephen, Based on your code above you have referenced an undeclared variable:

Object[][] data = { 
    {
        {
            "dd/mm/yyyy", 
            new Double(5), 
            new Boolean(false)
        },
        {
             "21/12/2013", 
             new Double(5), 
             new Boolean(false)
        }
    };

    String sDividendDate1 = (String)data[0][0]; 
    Double dDividend1 = (Double)data[0][1];

    try { 
        FileWriter file = new FileWriter(NewCodeFile); 
        BufferedWriter buffer = new BufferedWriter(file);
        buffer.write(sDividendDate1);
        buffer.newLine();
        buffer.write(dDividend1); /* you had this as sDividend1 which was not declared */
    } catch(Exception ex) {
        //catch logic here
    }

If you want to write Objects in a binary representation you should use an ObjectOutputStream
