求助: Socket的InputStream和OutputStream的问题

class MyRunnable implements java.lang.Runnable{
	public java.net.Socket __sc;
	public java.io.InputStream __is;
	public java.io.OutputStream __os;
	public java.io.ObjectInputStream __ois;
	public java.io.ObjectOutputStream __oos;
	
	public MyRunnable(Socket sc) throws IOException{
		
		__sc = sc;
		<strong>is = </strong>sc.getInputStream();
		<strong>os = </strong>sc.getOutputStream();	
		System.out.println("<strong>is and </strong>os getted");
		<strong>ois = new ObjectInputStream(</strong>is);
		<strong>oos = new ObjectOutputStream(</strong>oos);
		System.out.println("<strong>ois and </strong>oos getted");
	}
}
