Java Encapsulation and Get or Set Methods - thejavaconceptspart Java Encapsulation The meaning of Encapsulation is to make sure that "sensitive data" is hidden from users. To achieve this you must. Declare class variables/attributes as private. Provide public get and set methods to access and update the volume of a private variable. Get and Set Methods The Get Methods returns the variable value get and set method sets the value.

Buzzword in Java - thejavaconceptspart Buzzwords in Java The Feature of Java are also known as Java Buzzwords. A list of Most important features of Java language is given as below Simple Java is very easy to learn and it's syntax is simple, clean and easy to understand.There is no need to remove unreferenced objects because there is an Automatic Garbage Collection in Java. Object-oriented Java is an object oriented programming language. Everything in Java is an object. Basic concepts of OOPS are:- Object Class Inheritance Polymorphism Abstraction Encapsulation Portable Java is portable" refers to the SE version. It means that you can run java bytecode on any hardware that has a compliant JVM Platform Independent Java is platform independent because it is different from other language like c, c++ etc which can compiled into platform specific machine while

Wrapper Classes in Java - Java Programming - The Java Concepts Part Wrapper Classes in Java Each of Java's eight primitive data type has a class dedicated to it. These are known as wrapper classes because they "wrap" the primitive data type into an object of that class. To use lower case letters and Upper case letters in Java applications, Java has given a set of conventions Difference Between Primitive or Wrapper Class Primitive boolean, byte, char, int, float, double, long, short, Wrapper Class Boolean, Byte, Character, Integer, Float, Double, Long, Short, Example Wrapper Class public static void main(String [ ]args){ int i=10;//single value container Integer iRef=new Integer(i); int j=iRef.intValue(); Integer kRef=i; int L=kRef //Auto Unboxing)

Java Naming Conventions Java Naming Conventions Java is strictly a case sensitive programming language, where is Java applications there is a separate Recognization for lower case letters and for Upper case letters. To use lower case letters and Upper case letters in Java applications, Java has given a set of conventions All classes names, abstract classes names, interface names must be started with upper case letters and the sub sequent letters must also be upper case letters Ex: String, StringBuffer, InputStreamReader All Java variables names must be started with lower case letters buts the subsequent symbols must be Upper case letters Example: in, out, err, pageContext, bodyContent All the Java method names must be started with lower case letters but the subsequent Symbols must be Upper Case letters.

Java Java is an object-oriented programming language that produces software for multiple platforms. When a programmer writes a Java application, the compiled code (known as bytecode) runs on most operating systems (OS), including Windows, Linux and Mac OS)  Java Uses   Java is used as the server-side language for most back-end development projects, including those involving big data and Android development. Java is also commonly used for desktop computing, other mobile computing, games, and numerical computing.

  Advantages of OOP:  Object-Oriented Programming have the following advantages over conventional procedural and other approaches :  1. OOP provides a clear modular structure for programs. This makes it good for defining abstract data types where implementation details are hidden and clear interfaces are defined.  2. OOP makes it easy to maintain and modify existing code as new objects can be created with small changes to existing ones. 3. OOP provides a good framework for code libraries where software components can be easily taken and modified by the programmer. This is particularly useful for developing graphical user interfaces applications.

  Why Object Oriented Approach ?  A major factor in the invention of object oriented approach was to overcome some of the problems encountered with the procedural approach. In OOP, data is treated as a critical element and it is not allowed to flow freely. OOP bounds data closely with the functions that operate on it and protects it from accidental modification from outside world. OOP allows decomposition of a problem into a number of èntities called objects and then builds data and functions around these objects. A major advantage of OOP is code reusability.   Some important features of object oriented programming are as follows :  1. Emphasis is on data rather than procedure.  2. Programs are divided into several objects.  3. Data is hidden and can not be accessed by external functions. 4. Objects can communicate with each other through functions.  5. New data and functions can be easily added whenever necessary. 6. It follows the bottom-up approach. Learn Java – The Java Concepts 

  Advantages of top-down programming : Programming team stays focused on the goal.  Everyone knows his or her job.  By the time the programming starts there are no questions.  Code is easier to follow, since it is written methodically and with purpose.  Disadvantages of top-down programming: Top-down approach may complicate testing, since nothing executable will exist until the end of the project.  You have to provide a clear goal description in advance because all decisions depend on it.

  Top-Down and Bottom-up Approaches:  Top-down approach is a programming style. It is the base of traditional procedural languages, in which design begins by specifying complex pieces and then dividing them repeatedly into smaller pieces. The result of this breakdown is that the components are very specific and it becomes easier to write programs. This is the exact opposite of the bottom-up approach which is common in object oriented languages such as C++ and Java.  For writing a program using top-down approach we write the main procedure first. This main procedure contains names of all the major functions it will need. Then we look at these functions as individual procedure and the process is repeated again. These divided sub-procedures will eventually perform actions that are very simple and their coding can be done easily and concisely. When all the various sub-procedures have been coded, we have the complete solution. Learn Java... The Java Concepts Relative topics– Introduction St

  Introduction :  Object oriented programming (OOP) is the soul of Java. All Java programs follow the object oriented methodology. OOP is so important to Java that we must understand its basic principles before we can write even a simple Java program. Therefore, we will begin our study with a discussion of the theoretical concepts of Object Oriented Programming.  Structured Vs Object Oriented Programming :  As we know, every program consists of two elements :code and data. The code reflects "what is happening" and the data reflects "who is getting affected". A programmer can conceptually organize his program around its data. That is, some programs are written around code or around "what is happening" and others are written around "who is being affected." These are the two ways to construct our program. The first way is called the structured programming and supports process-oriented model. This approach treats a program as a series of linear step
