hi friend,

Check your code properly you have misplaced the closing curly braces

import java.io.*;

public class WriteByteArrayToFile 
{ 
    public static void main(String[] args) 
    {
        String strFilePath = "writingFilePath";
        FileOutputStream fos = null;
        try
        {
            fos = new FileOutputStream(strFilePath);
            FileInputStream fileinputstream = new FileInputStream("readingFilePath");
            int numberBytes = fileinputstream.available();
            byte bytearray[] = new byte[numberBytes];
            fileinputstream.read(bytearray);
            for(int i= 0;i < numberBytes;i++)
            {
                System.out.println(bytearray[i]);
            }
            fileinputstream.close();
        }
        catch(FileNotFoundException e)
        {
            System.out.println(e);
            /*MyReader mr = new MyReader();
            mr.ReadFile("side1-60.java");*/
        //}
        String strContent = "side1-60.java ";
        try {
            fos.write(strContent.getBytes());
            fos.close();
            }
        catch (IOException e1) 
        {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        }
   catch(IOException ex) 
   {
       System.out.println("FileNotFoundException : " + ex); 
   }
   catch(Exception ioe)
   {
       System.out.println("IOException : " + ioe); 
   }
}
}

Thanks.
