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.
What else can I help you with?
Can a method be declared in any order in a class?
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.
When an abstract modifier applied to a class?
An Abstract class is a special kind of class that cannot be instantiated. It has one or more methods which are not implemented in the class. These methods are declared abstract and they do not contain any code inside them. Ex: abstract class Parent { public abstract String getSon(); public abstract String getDaughter(); .... .... //More methods that contain specific behaviour/code in them } The above is an abstract class "Parent" that has a lot of functionality but it has declared two abstract methods which have no code inside them. Any class that has one or more abstract methods has to be abstract. This abstract class cannot be instantiated. i.e., the below piece of code will not work. The code will not even compile. Parent object = new Parent();
What does In public mean?
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.
What portions of a super class can be used by subclass?
Any members of a superclass which are declared as public or protected can be used by all subclasses.
What happens if an abstract modifier is applied to class. Explain?
The classes which have one or more abstract methods are abstract. To declare a class as abstract, use the abstract keyword in front of the class keyword, before the class declaration. Abstract classes cannot be instantiated. Similarly the new keyword cannot be used to create an object of the abstract class. Remember that the constructors and static variables cannot be declared as abstract. Any subclass of an abstract class must either implement all of the abstract methods in the superclass or be itself declared abstract.
When should a class be declared abstract?
In two situations:You want the child class to provide certain behavior while making sure that certain other behavior is as you want it (Through the concrete methods that you create)You dont want any other class to be able to instantiate your class
Is there any rule of cbse in which the 11th class student can not be declared failure?
is there any rule in cbse to fail in class 11th
What is object in methods in java?
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.
Does the abstract classes contain implementation for methods?
An Abstract class is a special kind of class that cannot be instantiated. It has one or more methods which are not implemented in the class. These methods are declared abstract and they do not contain any code inside them.Ex:abstract class Parent {public abstract String getSon();public abstract String getDaughter();........//More methods that contain specific behaviour/code in them}The above is an abstract class "Parent" that has a lot of functionality but it has declared two abstract methods which have no code inside them. Any class that has one or more abstract methods has to be abstract. This abstract class cannot be instantiated.i.e., the below piece of code will not work. The code will not even compile.Parent object = new Parent();Purpose of Abstract Classes:Abstract classes are generally used where you want an amount of behaviour to be used by the class that extends the abstract class while at the same time giving options to the child class to provide a certain amount of behaviour itself.A Child Class extending the Abstract Class:public class Child extends Parent {public String getSon() {return "Sons Name";}public String getDaughter(){return "Daughters Name";}...... //Code specific to the Child class}You can also have methods that have code implementation in the abstract class but those methods cannot have the abstract keyword in their method declaration.
Can instance methods replace class methods in programming?
No. never. An instance method cannot replace a class method because: Instance Methods - are normal methods that are linked to a class object instance Class Methods - are static methods that are not linked to any class object. These methods are not interchangeable and will create too many issues if we try to use one in place of the other.
What is meant by a class in java programming?
Class - A class can be defined as a template/ blue print that describe the behaviors/states that object of its type support.Classes in Java:A class is a blue print from which individual objects are created.A sample of a class is given below: public class Dog{ String breed; int age; String color; void barking(){ } void hungry(){ } void sleeping(){ } }A class can contain any of the following variable types.Local variables . variables defined inside methods, constructors or blocks are called local variables. The variable will be declared and initialized within the method and the variable will be destroyed when the method has completed.Instance variables . Instance variables are variables within a class but outside any method. These variables are instantiated when the class is loaded. Instance variables can be accessed from inside any method, constructor or blocks of that particular class.Class variables . Class variables are variables declared with in a class, outside any method, with the static keyword.A class can have any number of methods to access the value of various kind of methods. In the above example, barking(), hungry() and sleeping() are variables.
Can you overload destructor for your class?
No. Classes can only have one destructor, whether you define one yourself or allow the compiler to generate one for you. The compiler-generated destructor is public by default, does not release any memory allocated to any class' member pointers, and is non-virtual, which are the three main reasons for defining your own.
