		try
		{
			char ch;
			StringBuffer buff = new StringBuffer("");
			FileInputStream fis = new FileInputStream("sample.txt");
			while(fis.available()!=0)
			{
				ch = (char)fis.read();
				buff.append(ch);
			}
			fis.close();
			content = new String(buff);
		}
		catch(FileNotFoundException e)
		{
			System.out.println("Cannot find the specified file...");
		}
		catch(IOException i)
		{
			System.out.println("Cannot read file...");
		}
		g.drawString(content,20,20);
	}
}
