在JAVA中从txt字典文件中搜索单词

Question

enter image description here我编写了一个程序，用于通过文本文件字典搜索单词的含义。我已经通过服务器端加载了字典。我试图通过客户端向服务器发送一个单词，并接收该单词对应的含义。从客户端发送的消息将是：“搜索”+“放弃”。“放弃”由字符串值字表示

问题是，当我试图使用“c.equals（word）”这个方法在字典中查找单词时，它不起作用。但当我将字符串值替换为“放弃”时，程序运行良好。有人能帮我解决这个问题吗

import java.io.File;
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;
import java.util.Scanner;

public class Server {

    public static void main(String[] args) throws IOException{
        int port = 3000;
        byte [] data = new byte[1024];
        byte [] datas = new byte[1024];
        String word = null;
        String Message = null;
        String clientMessage = null;
        File f = new File("dictionary.txt");    //load the dictionary
        Scanner s = new Scanner(f);
        String c = null;

        while(true) {
            try {
                System.out.println("Waitting for a coonection on port 3000");
                DatagramPacket receivePacket = new  DatagramPacket(data,data.length);
                DatagramSocket serverSock = new DatagramSocket(port);
                serverSock.receive(receivePacket);
                InetAddress IPAddress = receivePacket.getAddress(); 
                int por = receivePacket.getPort();
                clientMessage = new String(receivePacket.getData());
                Scanner client = new Scanner(clientMessage);  //deal with the message send from client socket
                Message = client.next();     //get the first token from the client message
                if(Message.equals("Search")) { //determain the funtion
                    word = client.next();        //get the word that need to search through dictionary 
                    while(s.hasNextLine()) { 
                        String a = s.nextLine();
                        Scanner b = new Scanner(a);  // Scan the line one by one represented by b
                        c = b.next();                // find the first word of each line   
                        System.out.println(c);    //print c
                        System.out.println(word); //print word
                        if(c.equals(word)) { //if the first word of that line match with the word(send from client)
                            System.out.println(a);     //print out that particular line
                            break;
                        } else 
                            System.out.println("b");
                    }
                }
            }
      catch (IOException e)
      {
          System.out.printlin("Wrong"); 
      }
        }
    }
}

如果你还有任何问题，请告诉我

下面是打印c和word的结果 A. 放弃 A- 放弃 Aa 放弃 土豚 放弃 Ab- 放弃 船尾 放弃 放弃 放弃 被遗弃的 抛弃

从结果中，我们可以发现有一段时间c和word都是“放弃”的

至于我从客户端传输到服务器的消息，我添加了发送消息为“搜索”+“放弃”
