Method Overriding


Method Overriding

Changing the body that inherits from a super class to a sub class happens in Method Overriding. Only the method related to the created object is always executed. When the object is created, the object inherits the same method from the superclass but gives a different output than the output given by inheritance.


Figure 1: Method Overriding Example

As shown in Figure 1, object "M" is created for class "Man". Therefore, when the method called "climb" is called, only the method of the "Man" class will be executed. Therefore, the output is "using ladder".

Method Overloading vs Method Overriding

High school students are taught by teachers in a professional manner, but Kindergarten students are taught by teachers in a different way. Therefore, the same action "teach" will have different behaviors in different situations with different inputs. The same will happen in "Method Overloading". Simply put, a class in java can have multiple methods with the same name but different parameters.

There may be behaviors such as dancing, talking, teaching, where the parent and the child may have a different approach to performing the same behavior. For example, a parent and a child may have a common singing behavior, where the child's singing behavior may differ from that of its parent. The same happens in "Method Overriding". Simply put, a Java sub class can define methods with the same signature as the java super class.

Polymorphism

  Polymorphism After overriding a super class method in a sub class, casting and running the super class method through the super class reference is polymorphism. Simply put, the process of calling the sub class method from the super class reference using the 3 concepts of overriding, inheritance, and casting can be described as polymorphism. Figure 1 : Polymorphism Example As shown in this simple example, the subclass method is called by both upcasting and downcasting. Figure 2 : Polymorphism Example This code creates an " Employee " superclass and two subclasses, " Manager " and " Programmer ". The " Employee " superclass has a single method called " work " that simply prints out "The employee works". Both " Manager " and " Programmer " are subclasses of " Employee " and they override the " work " method with their respective tasks. The " Manager " subclass has an additional

Java Standards, Class & Object

Image
Java Standards, Class & Object Java is a popular programming language widely used for application development. One of the key features of Java is its support for templates, the powerful mechanism for creating objects through its class system. Objects are created from classes, which are like blueprints that define the properties and behavior of objects. Overall, Java's support for standards and its class system make it a powerful and versatile language for building a wide range of applications. Standards Class, variable, method can be mentioned as the parts that can be seen mainly in a java code. They have unique characteristics that make them easily recognizable in Java code. The first letter to start a class is always uppercase. The first letter initializing a variable is always lowercase. The first letter starting a method is always lowercase, and parentheses must be used at the end. Figure 1 :   Example According to the simple code shown in Figure 1,  class - Code, String va

Super Keyword

Image
  Super Keyword The super keyword is used to call the constructor of the super class from a sub class. The super keyword always calls the super class. All the methods and variables of the super class can be accessed from the sub class using the super keyword. Figure 1: Super keyword   Example As Figure 1 shows, the super keyword can be used to retrieve the output of all methods or only one method from the super class. When the super keyword is called to the constructor, the object is created for it and the corresponding output is executed.
