java从类返回字符串(linkedhashmap)

标签: java string map return

不确定标题是否有意义,但我试图从接收到Linkedhashmap的类返回Success消息,但是当我尝试编译文件时,eclipse会给我错误,提供

Remove arguments to match 'logFile()'

Create constructor 'logFile(Map<String, String>)'

如何设置发送Map并撤消String? 谢谢 领域

根据以下@Jeff Storey更正的代码,错误抑制为eclipse

调用类

 eventLog.put(stringA,stringB);
 logFile logStuff = new logFile();
 successRtn = logFile.Process(eventLog); 
   // Do Stuff with SuccessRtn

logFile类

 public class  logFile {
    static String Success = "Fail";

  public static String Process(Map<String, String> eventlog){
    // Do Stuff 
    Success = "Yeh!"
    return Success;
   }

  public static void main(String[] args){
  @SuppressWarnings("static-access")
  String result = new logFile().Procces(eventLog);
  System.out.println("result = " + result);
}

main 方法是一种特殊方法,当用作应用程序的入口点时,其签名必须为public static void main(String[] args)。创建第二个执行实际工作的方法,如下所示:

public class LogFile {

     public String process(Map<String,String> eventLog) {
        // do stuff
        return success;
     }

     public void main(String[] args) {
         // eventLog will probably be read from a filepath passed into the args
        String result = new LogFile().process(eventLog);
        System.out.println("result = " + result);
     }
}

请注意,许多命名约定也是非标准的。类应以大写字母开头,变量应以小写字母开头。
