✍🏻✍🏻......🍃🍃🍃......✍🏻✍🏻 Java Access Spacifier -------------------------------------- 1) Private :- members [method and variable] are only used in same class. 2) default :- if you not write any access specifier then it is consider default. Default members are accessible only with in same package 3) protected :- veritable, methods, and contractor, which are declared protected in a superclass can be accessed only by the subclasses in other package or any class with in the package of the protected members class 4) public :- A class, method, contractor, interface, etc. declared public can be accessed from any other class. Therefore fields, methods, blocks declared in side a public class can be accessed from any class belonging to java Universe. Join us @AFRICAN CODDER 😊

#Programming_Terminology

✍🏻✍🏻......🍃🍃🍃......✍🏻✍🏻 Q :- What is Constructor? (In JAVA) Answer: A constructor is a special method whose task is to initialize the object of its class. It is special because its name is the same as the class name. They do not have return types, not even void and therefore they cannot return values. They cannot be inherited, though a derived class can call the base class constructor. Constructor is invoked whenever an object of its associated class is created. @africa codder😊

##CLASS AND OBJECT IN JAVA:- 1 👉Classes It is a blueprint /a template that descrbe object of similar types. For examples, Mango, Apple and orange members of class fruit. Classes are user-defined that types and behave like the built-in types of a programming language. The syntax used to create an object is not different then the syntax used to create an integer object in java.If fruit has been defines as a class, then the statement Fruit Mango; Will create an object mango belonging to the class fruit. �            2👉Objects :- Objects are the basic run time entities in an object-oriented system. They may represent a person, a place, a bank account, a table of data or any item that the program has to handle. They may also represent user-defined data such as vectors, time and lists. Programming problem is analyzed in term of objects and the nature of communication between them. Program objects should be chosen such that they match closely with the real-world objects. Objects take up space in the memory and have an associated address like a record in Pascal. When a program is executed, the objects interact by sending messages to one another. For example, if “customer” and “account” are to object in a program, then the customer object may send a message to the count object requesting for the bank balance. Each object contain data, and code to manipulate data. Objects can interact without having to know details of each other’s data or code. It is a sufficient to know the type of message accepted, and the type of response returned by the objects.

Fundamental Programming Structures In Java Java Comments The java comments are statements that are not executed by the compiler and interpreter. The comments can be used to provide information or explanation about the variable, method, class or any statement. It can also be used to hide program code for specific time. Types of Java Comments There are 3 types of comments in java. 1. Single Line Comment 2. Multi Line Comment 3. Documentation Comment 1) Java Single Line Comment The single line comment is used to comment only one line. A single-line comment begins with a // and ends at the end of the line. Syntax Example //Comment //This is single line comment 2) Java Multi Line Comment This type of comment must begin with /* and end with */. Anything between these two comment symbols is ignored by the compiler. A multiline comment may be several lines long. Syntax Example /*Comment starts continues continues . . . Commnent ends*/ /* This is a multi line comment */ 3) Java Documentation Comment This type of comment is used to produce an HTML file that documents our program. The documentation comment begins with a /** and ends with a */. Java Programming language lay yalu comments enzi nachew 🙏

A class is an entity that determines how an object will behave and what the object will contain. A class is the basic building block of an object-oriented language such as Java. It is acting as a template that describes the data and behavior associated with instances of that class. When you instantiate a class means creating an object. The class contains set of variables and methods. The data associated with a class or object is stored in variables; the behavior associated with a class or object is implemented with methods. A class is a blueprint from which indi￾vidual objects are created. class MyClass { // field, //constructor, and // method declarations } Example: class Myclass{ public static void main(String[] args) { System.out.println(“Hello World!”); //Display the string. } } The keyword class begins the class definition for a class named name. The variables and methods of the class are embraced by the curly brackets that begin and end the class definition block. The “Hello World” application has no variables and has a single method named main. In Java, the simplest form of a class definition is class name { . . . }
