How do methods and functions differ?
A method is simply a function that is defined for a class. To invoke it, you usually need to specify an object, or the class name, followed by a dot, followed by the method name.A method is simply a function that is defined for a class.

In bluej can there be a method within a method?
No, Java only allows a method to be defined within a class, not within another method.
In java why method defined in super class need not to defined in subclass?
In Java, or in any object oriented language such as C++, a method defined in super (parent) class does not need to be defined in a subclass, because that is the primary purpose of inheritance. Object oriented programming allows you to define and declare a class that implements the behavior for an object. Inheritance allows you to refine, or subclass, that class by "reusing" all of the functionality of the parent class into the sub class, adding additional definition and declaration for the sub class. If the subclass needs to change a parent class method, it can overload that method. This is called abstraction.
What is function overriding in Java?
Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.
What is parent class in java?
Object Class is the parent class of all classes in java.Every class in the Java system is a descendant (direct or indirect) of the Object class.

A subclass can call constructor method defined by its super class?
True
What is the difference between in class and in the class?
Grammaticality there is some difference as the first one, "in class", is a little bit ambiguous. "In class" can mean both "In a class" and "In the class" but unless the class is defined before that statement it usually means "In a class". "In the class" always needs to have the class defined otherwise it is drawing upon unknown knowledge.

What is method overriding in vb net?
Method overriding in VB.NET occurs when a derived class provides a specific implementation of a method that is already defined in its base class. This is achieved by using the Overridable keyword in the base class method and the Overrides keyword in the derived class. It allows for polymorphism, enabling the derived class to modify the behavior of the base class method while maintaining the same method signature. Method overriding is essential for implementing dynamic method resolution at runtime.
Can this pointer be used within the concept of the static method?
No. When a method is declared static, it is defined outside of any individual class reference.
Is an abstract class virtual by default?
Unlike abstract class in C++, the abstract class in C# does not have any methods defined as virtual by default. The concept of virtual are not the same between C# and C++, either. Any virtual method must be defined explicitly in C#. Related to abstract methods - interestingly, an abstract class in C# does not have to have any abstract methods. However, the reverse, if a class need to have at least one abstract method, that class must be defined as abstract.
What is the difference between abstarct class and virctulfunction in C sharp?
They are not comparable, but may have some relationship between them.An abstract class is a class, while a virtual function (or method) is a method. A method must exist within a class. Hence, a class has methods, and the methods may be defined as virtual functions.A virtual function must be defined in a class, but that class does not have to be an abstract class. However, the purpose of a virtual function in C# is to provide a default behavior/implementation, while allowing the derived class to override that default implementation, hence it makes no sense to define a virtual function in a sealed class (a leaf, that is, no class can extend from it, and it is not an abstract class)Example:public class Parent {public virtual string MostCommonPhrase() {return "You better listen to me...";}}public class Child : Parent {public override string MostCommonPhrase() {return "You never listen to me...";}}
Difference between inheriting a method and overriding?
Inheriting a method means - a class is able to use a method that is declared in its parent class. Because of inheritance we need not re-declare the method in the child class again but still use it as it is. Overriding means re-declaring a method that is already available in the parent class in the child class to alter its features as per the requirement in the child class.
