Method Overloading




















Method Overloading



Figure 1: Method Overloading

The concept of method overloading is used when creating the same method repeatedly in the same class. This can be done by changing the parameter, which is called the method signature.

Figure 2: Method Overloading Example

Access Modifiers

The security which is used to access classes, methods and variables, is called modifiers. there are 4 types of modifiers.

  1. Public
    • Project, class in the project and other related classes can access.
  2. Protected
    • Class, package and sub classes can access.
  3. Default
    • Class and package can access.
  4. Private
    • Only the class can access.

Static

Static is a keyword that cannot be changed but used as a modifier. Variables, methods, classes in a class can be accessed from anywhere in it using the "static" keyword.

Polymorphism

Image
  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.
