错误:无法在 intelliJ IDE 中找到或加载主类 [英] Error: Could not find or load main class in intelliJ IDE

问题描述

我是 Java 的初学者，正在尝试使用 IntelliJ 运行我的代码，我刚刚安装了 JDK 1.7 作为我的 IDE.下面的一段代码甚至没有编译，并不断给我错误:

I'm a beginner in Java and am trying to run my code using IntelliJ that I just installed as my IDE with JDK 1.7. The following piece of code keeps does not even compile and keeps giving me the error:

Error: Could not find or load main class libTest

代码

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");
   }
}

我必须在编译器设置中进行任何更改吗??或者是代码.

Is there any change that i have to make in the compiler settings?? Or is it the code.

推荐答案

如果以上答案都不适合您，只需关闭您的 IntelliJ IDE 并从项目的根目录中删除 IntelliJ IDE 文件和文件夹:

If none of the above answers worked for you, just close your IntelliJ IDE and remove the IntelliJ IDE file and folder from the root of your project:

rm -rf .idea *.iml 

然后用 IntelliJ 打开项目.它现在必须工作.

Then open the project with IntelliJ. It must work now.
