一个J2ME上关于IO流的问题
我的目的是想访问放在本地的XML文件 

Java code

        InputStream is = getClass().getResourceAsStream("/city.xml");        int length = 0;        try {            while (is.read() != -1) {                length++;            }//            byte[] info = new byte[592892];            byte[] info = new byte[length];            is.read(info);            System.out.println(new String(info));        } catch (IOException e) {            e.printStackTrace();        }

Java code

InputStream is = getClass().getResourceAsStream("/city.xml");try {            byte[] info = new byte[is.available()];            is.read(info, 0, is.available());            System.out.println(new String(info, "GB2312"));        } catch (IOException e) {        }
