How is encapsulation linked with access modifiers?
a class can control what information or data can be accessible by other classes access modifiers sets usability of the methods defined in the class by other classes in either the same package or the other, this is how acces modifiers encapsulates the variables or the methods from being used . like there are 3 access modifiers-- 1.protected-can be used in the same class or class which has inherited it . 2.default-can be used in the same package,but no acces to other classes. 3.public-can be used by classes in different package.
Can a private method be overridden?
No. A method that is declared as private in a class is not inherited by any other class and hence if another class that extends this class declares a method with the same name and signature, it does not mean that this method is overridden. It is an entirely separate entity.
What is mean by class access?
Class access is the ability for any given class to access the functions of another class. Private access limits access to data and code just to the class that contains the private access modifier. The so-called "default" access grants private access, as well as access to any class in the same package. Protected access grants the same as "default" access, and also allows subclasses to access the code and data. Public access allows any class in any package to access the code and data.
What are the privileges granted to friend function?
Friend functions (and classes) have private access to the classes that declare them as friends. Although they have the same access rights as members of the class itself, friends are not themselves members of the class and cannot be inherited.
Are the private access specifiers in Java and C plus plus the same?
No.In Java, the private access modifier restricts member access to the class in which the member is declared. But in C++, private members are also accessible to friends of the class in which they are declared. The rough equivalent in Java would be package private access.Not that Java doesn't have access specifiers, it has access modifiers. When no modifier is specified, default access is implied, which is package private for classes and public for interfaces.

What is public class in java?
Generally to declare the class we use the public,abstract,final,strictfp and default modifiers. When ever we declare the class as public ,it mean public class A{} it is possible to access this class inside the same package and outside of the current package. ex: package name: pack This package contain the public class like package pack; public class A{} In this senario it is possible to access the in the same package "pack" like package pack; class Demo { public static void main(String args[]) { A a=new A(); } } And also it is posible to access the A class outside of the "pack" package like in anothe package like "pack1" package pack1; import pack.A; class Demo1 { public static void main(String args[]) { A a=new A(); } }
How the jvm is able to access your class even you declare it using default access specifier but the same class is not accessed from other class which is declared in another package?
The JVM knows about all of your classes, no matter what package they are in or what access specifier you declared them with. The access specifier is only used to limit access from other classes.
How do you import a self created class in java?
It's the same as importing any other class: import [package name].[class name];
What is mean by accessibility?
Class access is the ability for any given class to access the functions of another class. Private access limits access to data and code just to the class that contains the private access modifier. The so-called "default" access grants private access, as well as access to any class in the same package. Protected access grants the same as "default" access, and also allows subclasses to access the code and data. Public access allows any class in any package to access the code and data.

Is inherited and inherited traits the same thing?
I think you mean inherited and inherited traits - in which case yes - they're the same.
Is it possible to import package or class twice?
yes you can do that. The compiler does not complain about the fact that you imported a package or class more than once. However if you use an IDE like Eclipse it will tell you that you are using the same import multiple times. So remove it.
What is meant by default access of class in java?
That's what you get when you don't include any access specifier, such as "public" or "private". This default access gives access to any class in the same package.
What is another term for inherited behaviors?
