java輸入輸出和網(wǎng)絡(luò)編程實(shí)驗(yàn)報(bào)告

本次實(shí)驗(yàn)主要涉及Java輸入輸出和網(wǎng)絡(luò)編程。在本實(shí)驗(yàn)中,我們熟悉了Java輸入輸出和網(wǎng)絡(luò)編程的基本原理和操作。

在Java中,輸入輸出和網(wǎng)絡(luò)通信都是通過IO操作來實(shí)現(xiàn)的。我們主要使用了BufferedReader、InputStreamReader、PrintWriter、Socket等類。下面是實(shí)現(xiàn)讀取文件并輸出的代碼:

try {
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("input.txt")));
PrintWriter pw = new PrintWriter(new FileOutputStream("output.txt"));
String line;
while ((line = br.readLine()) != null) {
pw.println(line);
}
br.close();
pw.close();
} catch (IOException e) {
e.printStackTrace();
}

接下來我們實(shí)現(xiàn)了客戶端和服務(wù)器之間基本的通信??蛻舳送ㄟ^Socket對象連接服務(wù)器,并通過PrintWriter向服務(wù)器發(fā)送消息。服務(wù)器也使用Socket對象接收客戶端發(fā)來的消息,然后通過PrintWriter將消息輸出到客戶端。下面是簡單的代碼實(shí)現(xiàn):

// 服務(wù)器代碼
try {
ServerSocket serverSocket = new ServerSocket(9999);
Socket socket = serverSocket.accept();
BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter pw = new PrintWriter(socket.getOutputStream());
String line;
while ((line = br.readLine()) != null) {
pw.println(line);
pw.flush();
}
br.close();
pw.close();
serverSocket.close();
} catch (IOException e) {
e.printStackTrace();
}
// 客戶端代碼
try {
Socket socket = new Socket("localhost", 9999);
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintWriter out = new PrintWriter(socket.getOutputStream());
out.println("Hello world!");
out.flush();
String line = in.readLine();
System.out.println("服務(wù)器返回:" + line);
in.close();
out.close();
socket.close();
} catch (IOException e) {
e.printStackTrace();
}

通過本次實(shí)驗(yàn),我們更加深入地理解了Java輸入輸出和網(wǎng)絡(luò)編程的基本原理和操作,并通過實(shí)際代碼實(shí)現(xiàn)對其的應(yīng)用。
