错误：找不到或加载主类 - 新手 [英] Error: Could not find or load main class- Novice

问题描述

我是JAVA的新手。我已经得到这个文件没有找到异常，在文件中存在的文件存在我在路径中指定的那个

最初我有文件没有找到的问题。但是，在执行清理并重新运行后，现在我有一个问题，说

错误：找不到或加载主类main.main

  import Message * 
 import java.util。*; 
 import java.io.File; 
 import java.io.FileNotFoundException; 
 import java.io.FileReader; 
 import java.io.PrintWriter; 
 public class main {
 
 
 public static void main（String [] args）{
 
消息msg =新消息（bob，爱丽丝， 请求， 数据@@@@）; 
 MPasser passerObj = new MPasser（C：\\\Workspace\\config.txt，process1）; 
 
} 
} 
  

在MPasser构造函数中还有以下有一些相关的代码就是在那里

  public class MPasser（String file_name，String someVariable）{
 InputStream input; 
 try {
 input = new RandomAccessFile（file_name，r）; 
} catch（FileNotFoundException e）{
 e.printStackTrace（）; 
} 
 Yaml yaml = new Yaml（）; 
映射< String，String> Object =（Map< String，String>）yaml.load（input）; 
} 
  

对不起，我已经从初始查询进行编辑，以便更清楚

解决方案

在此行上：

  input = RandomAccessFile（C：\Workspace\conf.txt，'r'）; 
  

您需要转义 \ s

  input = RandomAccessFile（C：\\\Workspace\\\conf.txt，'r'） ; 
  

Hi I am a novice in JAVA. I have been getting this file not found exception inspite of the file existing in the very location I have specified in the path which is

Initially I had the issue of file not found. However, after performing a clean and re-run, now I am having an issue which says

Error: Could not find or load main class main.main

import Message.*;
import java.util.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.PrintWriter;
public class main{  


public static void main(String[] args) {

        Message msg=new Message("bob","alice","request","Data@@@@");
        MPasser passerObj=new MPasser("C:\\Workspace\\config.txt","process1");

    }
}

Also in the MPasser Constructor the following piece of relevant code is there

public class MPasser(String file_name,String someVariable){
    InputStream input;
        try {
            input =new RandomAccessFile(file_name,"r");
        } catch (FileNotFoundException e) {
            e.printStackTrace();        
            }
    Yaml yaml = new Yaml();
    Map<String, String> Object = (Map<String, String>) yaml.load(input);
}

Sorry I have made edits from initial query so that it is more clear

解决方案

On this line:

input = RandomAccessFile("C:\Workspace\conf.txt",'r');

You need to escape the \'s

input = RandomAccessFile("C:\\Workspace\\conf.txt",'r');
