为什么Java找不到符号

Question

我想从用户那里取五个名字，并在一个文本文件中收集它们，写下来：

 <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="HelloService.HelloService" behaviorConfiguration="mexBehaviour">
        <endpoint address="HelloService" contract="HelloService.IHelloService" binding="basicHttpBinding"></endpoint>
        <endpoint address="HelloService" contract="HelloService.IHelloService" binding="netTcpBinding"></endpoint>
        <endpoint address="mex" contract="IMetadataExchange" binding="mexHttpBinding"></endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8081/"/>
            <add baseAddress="net.tcp://localhost:8090/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mexBehaviour">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

它给了我一个错误。说＆＃34;找不到符号＆＃34;在第9行。为什么??

你需要为String数组调用new，如下所示

    String[] names= new String[5];
