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,我正在尝试使用IntelliJ运行我的代码,我刚刚安装了JDJ 1.7作为我的IDE。以下代码保持甚至不编译并一直给我错误:
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
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");
}
}
我必须在编译器设置??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
这可能有所帮助:
1)构建菜单 - >重建项目
。
有时Intellij不会重写类,因为它们已经存在,这样你就要求Intellij重写所有内容。
1) "Build" menu -> "Rebuild Project
".
Sometimes Intellij doesn't rewrite the classes because they already exist, this way you ask Intellij to rewrite everything.
2)运行菜单 - > 编辑配置
- >删除配置文件 - >添加配置文件(应用程序,如果它是Java应用程序),从主类下拉菜单中选择主类。
2) "Run" menu -> "Edit configuration
" -> delete the profile -> add back the profile ("Application" if it's a Java application), choose your main class from the "Main Class" dropdown menu.
3)构建菜单 - >重建项目
。
3)"Build" menu -> "Rebuild Project
".
