					Java Essentials need for Android App Developers?

Hello World! (always a cool way to begin a technical blog).

As covered in my previous blog post about Why you should learn Android Programming, I
would like to delve into the details of the Java essentials needed to commence learning
Android programming.

The bottom line is that you need to learn Java to start building your awesome android
apps. Here are some of the concepts, instructions and software that might prove highly
helpful in your endeavours to use them in Java as well as Android app development.

Java Essentials for Android App Developers




1. Programming Environment

     An ideal Java environment is critical to write Java code with ease and personal
      convenience. We recommend using the Eclipse IDE from the very beginning for all
      your Java as well as Android related programming.

2. Primitive Data types

     Data types form the very basics and the core of programming with Java. it’s important
      to learn in great detail about almost all data types that come in handy in day-to- day
      programming. They include character type, int type, float type, boolean etc.

                                                                  © VH Education Services Pvt. Ltd.
                                                                            http://venturehire.co
3. Strings

    Strings also form an essential part of Java programming. Implementations of
     concatenation, searching parts of string etc. are an important part of Java and prove
     on to be highly useful programming tools in the long run.

4. Selection Control Structures

    Conditional statements like if, if-else, switch etc. are quintessential when it comes to
     carrying out operations when certain conditions are fulfilled. They too form the crux
     of carrying out programming in any language.

5. Methods

    There are many instances when similar tasks need to be carried out multiple times
     within a program. Functions or methods come in handy here. You’ll use hundreds of
     functions when programming in any language hence it’s crucial to become adept in
     using them. Some of the implementations of functions might be to find the largest
     number among a list of numbers, searching a particular word in a string etc.

6. Classes

    In the real world, you’ll find many similar objects of the same kind. Java is essentially
     an object-oriented language, an aspect of it which differentiates it from many low-
     level programming languages such as C. Let’s take the example of a bicycle in the real
     world. Bicycles share properties of having two wheels, a seat etc. We can say that
     someone’s bicycle is an instance of the class of objects, bicycles. Even when
     programming in Java (and even in Android!), you might have to create classes that
     contain similar attributes and functions within them. Objects of that class can be
     called in a variety of situations to make programming efficient, simpler and more
     concise.

7. Inheritance, Interfaces and Abstract Classes

    Objects define their interaction with the outside world through the methods that they
     expose. Methods form the object’s interface with the outside world; the buttons on
     the front of your television set, for example, are the interface between you and the

                                                                   © VH Education Services Pvt. Ltd.
                                                                             http://venturehire.co
     electrical wiring on the other side of its plastic casing. You press the “power” button to
     turn the television on and off. In its most common form, an interface is a group of
     related methods with empty bodies. A bicycle’s behaviour, if specified as an interface,
     might appear as follows:



     interface Bicycle {




          //    wheel revolutions per minute


          void changeCadence(int newValue);




          void changeGear(int newValue);




          void speedUp(int increment);




          void applyBrakes(int decrement);


     }



8. Arrays

    An array is a container object that holds a fixed number of values of a single type.
     They are important in storing data of a particular type and are highly expedient when
     accessing data (especially when making lengthy android apps)

                                                                   © VH Education Services Pvt. Ltd.
                                                                             http://venturehire.co
