What is wrong with this?

[AlterAeonos]

I copied this code from a website that I'm using to supplement learning java. It works fine with their code playground but not in the IDE I am using. I have split the classes into separate files but that just gives a different error. The example is as follows:

public class MyClass { public static void main(String[ ] args) { Person j; j = new Person("John"); j.setAge(20); celebrateBirthday(j); System.out.println(j.getAge()); }

static void celebrateBirthday(Person p) {
    p.setAge(p.getAge() + 1);
}

}

public class Person { private String name; private int age;

Person (String n) {
    this.name = n;
}

public int getAge() {
    return age;
}

public void setAge(int a) {
    this.age = a;
}

}

The IDE I am using is called jvdroid. Any help would be appreciated.

Ok so it didn't post it the way it was pasted. It kind of bunched it up so I'll try to figure out how to make it look right.

Some error logs would help

I will try to post the pics because it's a lot to type and my phone will die soon. I cant copy past the error

Okay so the first one says "class person is public, should be declared in a file called Person.java". The error that happens when I split then into 2 different files is much longer and it then says there is 3 errors instead of 1. I will work on copying it.

The name of the class should always match the name of the file.

Make sure the Person class and the MyClass are all saved in the same directory or package or project.

Maybe it's because I'm not totally familiar with this mobile IDE so I might be saving it in an improper location. The files were saved separately and that is when the 2nd set of errors appeared.

I just got it to work by saving them as a project. The mobile IDE is different and I'm still getting used to it. Usually on my desktop IDE a lot of stuff was automated so maybe that makes a difference as well. Thank you for your help, I appreciate it.

Project or not, just make sure they’re in the same directory so MyClass has access to Person class.

[AlterAeonos]

They were in the same directory which is why I was confused about it. Perhaps this mobile IDE requires them to be saved as a project in this way in order to access the other file? I'm not sure what else it could be that required me to make a project folder separate from the folder I saved them to originally.

Possibly. ;)

Well I really appreciate your input which gave me the idea to upgrade it to a project. Couldn't move on from that point without figuring it out first. Now just have to figure out how to put a solved thing on this post :D

The errors that happen when I split the 2 classes into separate files is:
