Yes. There is no specific order in which the compiler expects methods to be present. As long as the method is inside the class it is perfectly fine.
Yes, there is a difference in the way a class method is defined depending on where it is declared.
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.
Local Variables There are two types of variables based on the location of declaration 1. Instance Variables- Declared inside a class, but outside of any method's body. 2. Local Variables- Declared inside a method's body inside a class.
False.Any method declared as final cannot be overridden by any subclasses.You also cannot technically override a private method. While your subclass can have a method with the same definition as a private method in the superclass, it does not actually override that method.
Yes. Any base class method that is declared virtual can be overridden by a derived class. Overriding a method that is not declared virtual can still be called, but will not be called polymorphically. That is, if you call the base class method, the base class method will execute, not the override. To call a non-virtual override you must call it explicitly.

No. When a method is declared static, it is defined outside of any individual class reference.
The keyword public is an access specifier. A variable or a method that is declared public is publicly accessible to any member of the project. Any class or method can freely access other public methods and variables of another class.
A friend is any class, class method or function that is declared to be a friend of a class. Friends have private access to the classes that declare them friends.

I guess an object in a method would be any object variable, used within a method. An object variable of course is a variable that is declared as a variable of a certain class type.
The Scope of a variable defines the areas of a program where this variable would be visible and can be used. For ex: a. Method variables - are visible only inside the method where they are declared and hence their scope is only the method b. Class variables - are visible inside the class and can be used by any method inside the class and hence their scope is the whole class.
public: It can be called (method) or accessed (field) from any class in any package.static: It is declared on the class rather than the object. If a method, you do not need an object to call it, it can be called directly on the class. If a field, there is only one variable for the class, not one per object.final: If a method, the method cannot be overridden. If a field, the value cannot be changed (a constant).int: If a method, the return type. If a field, the field type (it can only hold values of type 'int'). int is the primitive integer type.
