	public static void main(String[] args) {
		try {
			FileReader input = new FileReader("c:\\qq\\write.txt");
			FileWriter output = new FileWriter("c:\\qq\\temp.txt");
			int read = input.read();		
			while ( read != -1 ) {
				output.write(read);	
				read = input.read();
			   }			
			input.close();
			output.close();
