	public static void main(String args[])
	{
		try
		{
	    	BufferedOutputStream out=new BufferedOutputStream(new FileOutputStream("hello.txt"));
			out.write("hello world中国".getBytes());
			String a="ab中国";
			byte b[]=a.getBytes();
		
		
			System.out.print(b.length);
			out.close();
		}
		catch(IOException e)
		{
			e.printStackTrace();
		}

		try
		{
			BufferedInputStream in = new BufferedInputStream(new FileInputStream("hello.txt"));
			int c;
		
			while((c=in.read())!=-1)
				System.out.print((char)c);
			
			System.out.println();
