我是Java初学者,正在尝试使用IntelliJ运行我的代码,我刚刚将它安装为JDK 1.7的IDE。下面这段代码甚至不能编译,并不断给我错误:

Error: Could not find or load main class libTest

Code

import java.lang.Integer;
import java.lang.String;
import java.lang.System;
import java.util.*;

class book {

    private String name = "trial";
    private int bookCode=1;
    private int issued=0;

     public void Issue(){
         if(issued==0) {
             issued=1;
             System.out.println("You have succesfully issued the book");
         }
         else {
             System.out.println("The book is already issued. Please contact the librarian for further details");
         }
    }

    public int checkCode() {
        return bookCode;
    }

    String readName() {
        return name;
    }

    public void setName(String newName){
        name=newName;
    }

    public void setBookCode(int newCode){
        bookCode=newCode;
    }
}

class library {
    private ArrayList books=new ArrayList();

    public void getList(){
        for(int bk:books){
            String bName=books(bk).readName();
            System.out.println((bk+1)+")  "+bName);
        }
    }
}

public class libTest{
    public static void main(String[] args){
        library newLib= new library();
        System.out.println("code working");
   }
}

有任何改变,我必须在编译器设置??或者是代码。

对我来说,我尝试了上面的几个选项,没有工作。然后我只是重命名了我的Application类,这可能迫使intelliJ构建一个新的jar和错误消息开始改变。然后我重新命名它,它工作。

其他回答

尝试检查您的项目名称和完整目录名称,看看是否包含任何“非英语”单词(如亚洲单词),有时这可能是错误的。重命名项目名称或项目路径包含这样的单词并重新打开它可能有效。

我已经尝试了这里建议的所有方法,但都无济于事。最后,我简单地创建了一个新的Maven应用程序,并逐个手动地将pom.xml和java文件和资源复制到其中。现在一切都正常了。我是IntelliJ的新手,完全没有印象,但它很容易进入不稳定的状态。

在intelliJ中创建项目后,尝试运行以下命令:

mvn package

I am working with Kotlin but am guessing the problem is the same. I would start a project, create a single file and add main to it and the IDE couldn't find the main. I tried the things in this list and none worked. I finally mentioned my frustration on one of the IntelliJ pages and was contacted. Of course, it worked fine for IntelliJ. After a couple of days back and forth, I noticed that the highlight function wasn't working and mentioned that. It turned out something was wrong with the IDE settings. I still don't know specifically what was wrong but the fix in my case was to reset the IDE settings. File->Manage IDE Settings->Restore Default settings. After this, the green triangle start icon became visible to the left of my main function and things continued to work normally for subsequent projects.

我从其他地方继承了一堆. java文件,不知道如何让它们在任何IDE中工作。最终,我不得不转到Main.JAVA文件所在的命令行,运行javac Main.JAVA。这创建了一堆. class文件。然后IDE就能够弄清楚要做什么。
