Java IO 流分为输入流InputStream 和输出流OutputStream
输入流 |
输出流 |
InputStream |
OutputStream |
读进来 |
写出去 |
读到程序内存 |
写出到流里面 |
1、客户端
public static void main(String[] args) throws IOException {
new Thread(() -> {
Socket socket = null;
try {
socket = new Socket("", 3333);
} catch (IOException e) {
e.printStackTrace();
}
try {
while (true) {
OutputStream outputStream = socket.getOutputStream();
String format = DateFormat.getDateTimeInstance().format(new Date());
outputStream.write((format + " hello world!").getBytes());
Thread.sleep(2000);
}
} catch (Exception e) {
}
}).start();
}

public static void main(String[] args) throws Exception {
ServerSocket serverSocket = new ServerSocket(3333);
new Thread(() -> {
while (true) {
try {
Socket accept = serverSocket.accept();
new Thread(() -> {
try {
int len;
byte[] data = new byte[1024];
InputStream inputStream = accept.getInputStream();
while ((len = inputStream.read(data)) != -1) {
System.out.println(new String(data, 0, len));
}
} catch (IOException e) {
e.printStackTrace();
}
}).start();
} catch (Exception e) {
}
}
}).start();
