Can we inherit private class?
Members of a class that are declared private are not inherited by subclasses of that class. Only members of a class that are declared protected or public are inherited by subclasses declared in a package other than the one in which the class is declared. The answer is No. They do not.Can we inherit private class in Java?
A java private member cannot be inherited as it is available only to the declared java class. Since the private members cannot be inherited, there is no place for discussion on java runtime overloading or java overriding (polymorphism) features.Can private class be inherited C++?
the private members of the base class cannot be accessed by the derived class. the interface of the base class is not being inherited but its implementation is being inherited which means one can use the contents of the base class as it is using the member functions of the derived class.Does a derived class inherit private members?
The derived class doesn't "inherit" the private members of the base class in any way - it can't access them, so it doesn't "inherit" them.What is a nesting class?
A nested class is a class which is declared in another enclosing class. A nested class is a member and as such has the same access rights as any other member. The members of an enclosing class have no special access to members of a nested class; the usual access rules shall be obeyed.OOP Class Inheritance and Private Class Members - Python for Beginners!
Can we overload a private method?
Yes, we can overload private methods in Java but, you can access these from the same class.Is Private methods are final in inheritance?
So, to answer question 2, yes, all compilers will treat private methods as final . The compiler will not allow any private method to be overridden. Likewise, all compilers will prevent subclasses from overriding final methods.Can we override inner class?
No, you cannot override private methods in Java, private methods are non-virtual in Java and access differently than non-private one. Since method overriding can only be done on derived class and private methods are not accessible in a subclass, you just can not override them.Can abstract method be overridden?
An abstract method is a method that is declared, but contains no implementation. you can override both abstract and normal methods inside an abstract class. only methods declared as final cannot be overridden.Can we override static method?
Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.Can we make class as static in Java?
So, Yes, you can declare a class static in Java, provided the class is inside a top-level class. Such clauses are also known as nested classes and they can be declared static, but if you are thinking to make a top-level class static in Java, then it's not allowed.Can constructor be private?
Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.Can method be declared static?
Static methodsWhen a method is declared with the static keyword, it is known as the static method. The most common example of a static method is the main( ) method. As discussed above, Any static member can be accessed before any objects of its class are created, and without reference to any object.
Can we override protected method as private?
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.Can we override abstract method in Java?
A subclass must override all abstract methods of an abstract class. However, if the subclass is declared abstract, it's not mandatory to override abstract methods.Which operator Cannot overload?
Which of the following operator cannot be overloaded? Explanation: ?:, :: and . cannot be overloaded +, -, % can be overloaded.Which method we Cannot be override?
Can we override a static method? No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods.Can we make constructor static?
No, we cannot define a static constructor in Java, If we are trying to define a constructor with the static keyword a compile-time error will occur. In general, static means class level. A constructor will be used to assign initial values for the instance variables.Can we use final keyword before constructor?
declaring constructor as finalIn other words, constructors cannot be inherited in Java, therefore, you cannot override constructors. So, writing final before constructors make no sense. Therefore, java does not allow final keyword before a constructor.
Can a abstract class be declared final?
Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation. However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.Can static methods be private?
Yes, we can have private methods or private static methods in an interface in Java 9.Can we create immutable class in Java?
Immutable class in java means that once an object is created, we cannot change its content. In Java, all the wrapper classes (like Integer, Boolean, Byte, Short) and String class is immutable. We can create our own immutable class as well.Can we create object for private class?
yes. private is an access modifier, as you might have learned that restricts member to be access just within declaring scope. So as a member of another class , private class can be accessed in that class only.Can we declare a class as final?
A class can be made final by using the final keyword. The final class cannot be inherited and so the final keyword is commonly used with a class to prevent inheritance.Can a outer class be static?
We can't declare outer (top level) class as static because the static keyword is meant for providing memory and executing logic without creating Objects, a class does not have a value logic directly, so the static keyword is not allowed for outer class.
