java io比较

java有三种io

1、io

public class Sever {

private ServerSocket serverSocket;

private Socket socket;

public Sever(){

try {
serverSocket = new ServerSocket(8080);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
/**
* */
public void start(){
while(true){
try {
//使用accept()阻塞等待客户请求，
//请求到来则产生一个Socket对象，并继续执行
socket = serverSocket.accept();
} catch (IOException e) {
e.printStackTrace();
}
}
}
/**
* 得到输入流
* */
public InputStream getInputStream(){
try {
return socket.getInputStream();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
/**
* 得到输出流
* */
public OutputStream getOutputStream() throws Exception{
return socket.getOutputStream();
}
}
