what is the difference between `public class` and

Question

I have noticed that if don't write public before a class its works same as like a public class. I can't understand why so? It should show a error when I don't declare a class as public, private or protected. But it works fine. What is the reason?

Answer 1

For declarations of classes are avaible only two keywords:

• public .Example: public class Student{//...}
• private package(as default) .Example: class Note{//...} .It is visible only in his package.

You can use private and protected only if you declare an member inside of a class. Example:

public class Student{
protected Note note;
}
