Error: Could not find or load main class in intelliJ IDE
If you receive the error "Could not find or load main class" in IntelliJ IDEA, it means that the Java Virtual Machine (JVM) cannot find the class with the main method that you are trying to run.
There are several possible reasons for this error:
The class name is spelled incorrectly: Make sure that you have spelled the class name correctly in the "Run/Debug Configurations" dialog.
The class is not in the correct package: Make sure that the class is in the correct package. If the class is in a package other than the default package, you need to specify the fully qualified class name (including the package name) in the "Run/Debug Configurations" dialog.
The classpath is not set correctly: Make sure that the classpath is set correctly in the "Run/Debug Configurations" dialog. The classpath should include all the directories and jars that contain the classes that you are trying to run.
There are multiple classes with the same name: If you have multiple classes with the same name, you need to specify the fully qualified class name (including the package name) in the "Run/Debug Configurations" dialog.
To fix the "Could not find or load main class" error, you need to identify the cause of the problem and take the appropriate action. You may need to check the spelling of the class name, make sure that the class is in the correct package, set the classpath correctly, or specify the fully qualified class name if you have multiple classes with the same name.
