用Java实现网络连接的时候只能用DataInputStream，DataOutputStrame吗？
如果想用ObjectInputStream，ObjectOutputStream能不能实现，本人试了，不行，但是我想Java不会功能那么小吧，请高人指点一下。

- Java code
public class Client { public static void main(String[] arg) { try { Employee joe = new Employee(150, "Joe"); System.out.println("employeeNumber= " + joe.getEmployeeNumber()); System.out.println("employeeName= " + joe.getEmployeeName()); Socket socketConnection = new Socket("127.0.0.1", 11111); ObjectOutputStream clientOutputStream = new ObjectOutputStream( socketConnection.getOutputStream()); ObjectInputStream clientInputStream = new ObjectInputStream( socketConnection.getInputStream()); clientOutputStream.writeObject(joe); joe = (Employee) clientInputStream.readObject(); System.out.println("employeeNumber= " + joe.getEmployeeNumber()); System.out.println("employeeName= " + joe.getEmployeeName()); clientOutputStream.close(); clientInputStream.close(); } catch (Exception e) { System.out.println(e); } } }
