Java is the word's #1 Programming language



Let’s take a look at how the language of Java is expressed in the code we write. The language itself is a collection of keywords and symbols that we put together to express how we want our code to run. Each line of code has certain rules (or grammar) about how it needs to be constructed and what is or isn’t allowed.
Remember, programming languages are abstractions, meaning that they abstract the true underpinnings of how a computer operates into things we can more easily understand. Behind the scenes it really is all ones and zeroes, but we don’t need to concern ourselves with that. We can think in these abstract terms to express our ideas and commands, and these abstractions apply across all different types of programming.

Inheritance in Java

Inheritance in Java Inheritance  is one of the feature of Object-Oriented Programming (OOPs). Inheritance allows a class to use the properties and methods of another class. In other words, the derived class inherits the states and behaviors from the base class. The derived class is also called subclass and the base class is also known as super-class . The derived class can add its own additional variables and methods. These additional variable and methods differentiates the derived class from the base class. Inheritance is a  compile-time  mechanism. A super-class can have any number of subclasses . But a subclass can have only one superclass. This is because Java does not support multiple inheritance. The superclass and subclass have  “is-a”  relationship between them. Let’s have a look at the example below. Inheritance  Example Let’s consider a superclass  Vehicle . Different vehicles have different features and properties howeve...

Switch Case

Syntax : Switch Case in Java Programming It is alternative to else-if ladder. Switch Case Syntax is similar to – C/C++  Switch. Switch allows you to choose a block of statements to run from a selection of code, based on the return value of an expression. The expression used in the switch statement must return an  int, a String, or an enumerated value . switch (selection) { // value case value1 : // checking value 1 statement ( s ) ; break ; // use to break switch flow if condition match case value2 : // checking value 2 statement ( s ) ; break ; . . case value_n : statement ( s ) ; break ; default : statement ( s ) ; } Different Ways of Using Switch Case : Switch Case Using Integer Case int i=3; switch (i) { case 1 : System . out . println ( "One player is playing this game." ) ; break ; case 2 : System . out . println ( "Two players are playing ...

JAVA BASICS (OOPs Concepts)

OOPs Basics Java is known as an Object Oriented language. So,  what does Object Oriented mean ? It means that the  foundations  of any kind of  program constructed in Java  might be imagined in terms of  Objects . Note  : Above are the links of separate detailed tutorials on each topic. However if you want to brush up the things for interview, below is a brief of each of the above topic which will help you re-call the things. a) Data b) Instructions for processing that data into a self-sufficient ‘object’ that can be used within a program or in other programs. Advantage of Object Oriented Programming a) Objects are modeled on real world entities. b) This enables modeling complex systems of real world into manageable software solutions. Programming techniques a)  Unstructured Programming  (Assembly language programming) b)  Procedural Programming  (Assembly language, C programming) c)  Object Orien...
