Java 语句，但不在客户端程序中执行

我正在尝试从服务器读取一个文件，并且能够成功地完成。但是，在客户端，while循环之后的语句根本不执行。请帮我处理这个请求。请求客户端输入的行根本不显示。请帮忙

相反，我建议您使用
Scanner
读取文件
您的代码看起来像…（在服务器端）

我在第一次回复时犯了错误，我读得太快了。我删除了它。我现在将重新阅读代码。原因之一可能是一些
异常
！向代码格式化程序致敬：-）但是，分号是必要的。否则它会导致语法错误。你可以发布相关代码吗？代码太多了。你还可以指出循环卡住时哪个
？用
e.printStackTrace（）替换
catch（）
的正文
和runI我认为在服务器端的实际代码中，由于exception@boxed__l对该注释+1。也尝试了…获取文件内容后的下一行仍然没有执行…wen尝试在服务器中使用pwrite.close，然后该行执行，但套接字本身被关闭：-（@user2582322…我忘了添加文件对象，请查看更新的代码
Scanner scnFile=new Scanner(new File("display_client.txt")); //give absolute path if necessary

while(scnFile.hasNext()){

System.out.println(scnFile.nextLine());

}

scnFile.close();
