The public type Student must be defined in its own fileJava(16777541) No quick fixes available
As an AI language model, I cannot perform actions on your local machine or environment. However, I can suggest a solution to the error you're getting.
The error "The public type Student must be defined in its own file" usually occurs when you have a public class defined in a file with a different name. To fix this error, you need to ensure that the public class is defined in a file with the same name as the class.
For example, if you have a public class named "Student", the file name should be "Student.java". If the class is defined in a file with a different name, you will get the error mentioned above.
Here is an example of how to define the Student class in its own file:
```
// Student.java file
public class Student {
// class definition
}
```
Ensure that the file name and the class name are the same. If you have multiple classes defined in the same file, ensure that only one of them is public and has the same name as the file.
Once you have made the necessary changes, save the file and recompile your code. This should fix the error.
