A MUST KNOW JAVA BASICS FOR ANDROID DEVELOPMENT
Image source : educratsweb.com
Tag : # A,

Java is the most recommended application to develop native apps along with Android SDK. Java and Android make the best combination to provide tremendous user experienced features in apps. Developers also feel very comfortable to make mobile application development using Java, as it is OOPs-based programming language. Java syntax also simplifies development tasks to the app makers and make the way for deploying many applications in a shorter period.

Why Java is the best programming language?

Programming languages are there to communicate with the computer machines to instruct tasks such as manipulating, collecting, and displaying the data. If we say deep, the processor of a computer sends and receives the electrical signals to control the processes. Programming languages like Java used to write these instructions using symbols and words. The computer will translate these instructions to the user and machines. Java is a high-level programming language that can be understood easily by the user as well as computing machines. 

Uniqueness of Java

Java has two main features such as statistically typed and object-oriented programming. 

  • Statistically typed means processing with data. It has variables that are the container of data and Java requires the user to declare the variable to fetch the data for processing. 

  • Object-oriented on the other hand, working with objects and classes that are allows us to define and access the properties of a particular process. 

Java and JavaScript, both are different

Java and JavaScript are not the same or related things. Java is the programming language and JavaScript is a scripting language. Both have different works and to be written codes differently. However, both languages allow us to use variables, operators, methods, and objects. 

Components of Java

Java has a collection of inbuilt keywords and symbols to describe the instructions of rule-based codes for the execution of some tasks. It has abstraction to hide unnecessary things such as machine code that are only with zeros and ones to make a better understanding of the developers and users. 

Data Types of Java

Data types are the keywords that define the type of data to store and access information. The various types of data are as follows: 

  • int – whole integer value includes and negative numbers

  • float – decimal numbers used for currency and temperatures.

  • boolean – bit values such as true or false that represented by 0 and 1. 

  • char – single characters such as a, A, and symbols such as #, $. Also, it is case sensitive.

  • String – a group of characters that means a word.

Variables of Java

Variables are the container to hold the data that can be used to call the value by calling the variable name itself. It is defined as follows:

Data_type Variable_name = “Value”

Example: 

int number = 21;

float temperature = 101.2;

boolean isEmpty = true;

char firstLetter = ‘C’;

Methods of Java

A method is the group of data to be called anywhere in the code by its method name. It is used to reuse some repeatable codes to avoid code repetition. It saves a lot of time and energy for the developers to concentrate more on project objectives. 

Example

public int length()

{ int numberofCharacters = 0;

----some source codes----

return number of characters;

}

Calling with the method name

If we use the above method to any part of the programming codes, it requires to be called by its name for accessing the process.

Example:

String sampleText = “Java is easy to learn”;

int textLength = sampleText.length();

Java for Android

Once you through with the above major concepts of Java, you can develop Android mobile applications easily. 

Steps to create an Android app using Java in Android SDE:

  1. Create a new project with more layouts and creative designs of your choice

  2. Name the developing application and Select Java as the programming language

  3. Fetch the mainactivity() class from the drop-down which is near to the project name.

  4. Add new classes as of your requirements.

  5. Call the resource field by checking the layouts, drawable, and values.

  6. Drag and drop components to the workspace as of your project

  7. Connect the related code from the virtual device to execute the application.

Future of Java in Android Development

Java is the best choice of the programming language as it has the following features to simplify the mobile app development in the Android platform

  • Tremendous resources such as libraries, methods, packages

  • Easy documentation that makes easy to learn and deploy the app

Even though Kotlin used for Android development, there are many additional features in Java such as OOPs, Multithreading, Enumeration, Auto Boxing, Auto Unboxing, Annotations, Generics, String Handling, Java.lang, Collections framework, Java I/O, and Networking, which cannot be found in any other programming languages like Kotlin. 

Conclusion

Java makes android development simple and effective with its featured options. It solves algorithm-oriented problems and processes using Java components.
