JAVA MASTERY 2024: EASY JAVA

What is JAVA?  

JAVA was developed by James Gosling at Sun Microsystems Inc. in 1995 and later acquired by Oracle Corporation. Java programming  language was developed 25 years back. And still, it didn’t lose its  popularity. Java is a widely used object-oriented programming  language and software platform that works on billions of devices, including  notebook computers, mobile devices, gaming , medical devices and many others  . The rules of Java are based on the C and C++ languages. The most  important benefit of using java is its portability. Once you write some code  for a Java program on a notebook computer, it can be easily moved to a  mobile device. Java is that technology which is used in both a programming  language and a software platform. Here what Java programming involves:- 

 

  • Writing Codes: – Developers write java code using a text editor or  IDE, this code is very essential to set instructions in specific syntax  that java will understand.  
  • Assembling: – Now after the code is written it needs to be translated  in that language which a computer can understand, then java code is  combined or assembled in a format called bytecode. 
  • Byte code: – Byte code is a set of instructions for Java Virtual  Machine (JVM), it is something like a universal language which any  device can understand just having JVM in it.  
  • Implementation: – Now the byte code is executed by JVM which  translates into machine language /code which computer can  understand, now this is how with the help of JVM java can perform on  any device.  
  • Making Apps: – Developers can make a lot of apps using java like  web applications, mobile apps, desktop software and even games can  be made from it as well.  

MASTERING JAVA NEW FEATURES:- 

Mastering every new features of java is very essential for keeping yourself  up to date here are java new features. 

JAVA 8 

Oracle released a new version of Java as Java 8 on March 18, 2014. It was  a huge release of Java for a software development platform. It has a lot  of different upgrades to the Java programming, JVM, Tools and libraries.  

Lambda Expression: – 

  • Lambda expression helps us to write our code in a functional style. It also  provides a clear way to implement the Single Abstract Method by using an  expression. It is very important and useful in the collection library in which it  helps to filter and extract data. 

STREAM API:-

  • Stream API is a feature that was introduced in Java 8 that allows developers  to easily process collections of objects, it also helps in powerful operations  like filtering, mapping and reducing .  

OPTIONAL CLASS:- 

  • This is that feature which helps to handle potentially null values more  effectively and avoid NullPointerException, It provides methods that help  to check the presence of a particular variable and value.  

 

JAVA 9

Oracle has released Java 9 with lots of new features. It includes various  upgrades to the Java programming, JVM, Tools and libraries, these are  common and important features in java 9.

Module System (Jigsaw Project )

  • It is a new kind of Java programming that can be used to collect Java code. The main purpose of this project is to easily reduce the number of applications to  small devices. In Java 9, JDK has been divided into a set of modules to make it  easier.  

JShell :- 

  • It is an interactive Java Shell tool, it allows us to separate Java code from  the shell and shows output immediately. JShell is a REPL tool and runs from  the command line, though this coding feature does not need to  compile files. 

 

JAVA 10 

Java 10 is the fastest release of a java version in its 23-year history. Java  has been criticized for its slow growth, but Java 10 just shut down that  concept, here are its common features;- 

Local Variable Type Inference :- 

  • It helps to use var keyword for local variable type inference, it is one of the  new Java 10 features for developers. It is easy to understand by this example 

Optional.orElseThrow() :- 

  • Java 10 introduced a new method orElseThrow in the optical class, for  throwing specific exceptions when a value is not present.  

 

CODING AND DESIGN:- 

CODING:- 

Coding is known as computer programming is how we communicate with  computers and tell them what to do. Coding can be used to make  programs, including websites and apps. It creates instructions for computers  which can be followed. Here are some important point of coding;- 

Programming Language 

  • There are lots of common languages which are used for coding such as  Java, Python, JavaScript, C++ and many more but they are the most used ones.  

Syntax and Semantics 

  • Syntax is a kind of rule that shows how a program is written and how it  should be structured. Syntax and semantics make us understand rules and  conventions for writing codes.  

Problem Solving 

  • Develop problem solving skills to handle challenges and apply solutions.

Algorithmic Thinking 

  • Learn algorithm and data structure to make code work perfectly  

Coding Practice 

  • For best in coding it should be very clear, modular and maintained code. 

Where to learn 

  • Coding is very important nowadays so it is essential for everyone to learn  about it. It can be learned from boot camps, websites or from some trusted  apps.  

DESIGN

Design means to design a software through planning, user interfaces (UI),  and user experience (UX).  

Architecture Design:- 

  • In this step developers have to plan an overall structure of that particular  software which they are developing. 

User Interface (UI):- 

  • UI design the visual element and create the graphical portions of mobile  apps, websites, and devices—the elements that a customer directly interacts  with. UI designer work is to make websites visually attractive and easy to use.  

User Experience (UX):- 

  • UX design focuses on overall work, it monitors the experience of customers  for their product. UX designer work is to make software enjoyable, and  easy for customers. 

 

TOP 10 TIPS FOR EVERY JAVA PROGRAMMER  SHOULD KNOW IN 2024:- 

Java is a very popular programming language, so it is getting updated very  frequently so there are 10 tips which should be kept in mind;- 

  • Stay Updated

Every developer should be aware of the latest and upcoming versions of java,  to ensure their work is accurate at all times.  

  • Get mastery in New Java Features 

Get your basics clear and then learn about modern java features like  records, pattern matching, sealed classes. Having knowledge of every new  feature will help you in coding.  

  • Practice Coding 

Practice programming online or offline, that’ll enhance your self-confidence. Be  regular and consistent, make targets and try to complete them on a regular  basis. Give some tests of java programming from some sites like CodeChef,  Spoj, and Project Euler. 

  • Projects 

A perfect way to improve your coding skills and become a good programmer is  to work as a freelancer individually. It means that you find projects  online, work from home, and get paid online, too. 

  • Modular Development 

Modular development promotes better code organizations, using the Java  module system

  • Automate Testing 

Apply automated testing like JUnit, or Gitlab CI into your development  work, because of it code quality gets better. 

  • Clean Code Principle 

Write clean, readable codes which follow coding standards, and adopt  Clean Code principles from Robert C. Martin such as SOLID, DRY, KISS to  write code that is easily understandable.  

  • Dedicate Yourself 

Don’t have a casual approach about being a java developer and concentrate and  have your focus on it. Learn from different mediums and do self-practice.  

  • Take advantage of Generic 

Generics allow you to use reusable code that can work with different  data types. By using generics, you can assure type safety and remove  the need for explicit type casting.  

  • Group Discussion 

When learning it is best to make a group, and have discussions. Join  groups on the internet. Group discussions help you to get a different  understanding regarding the topic. You can get the good and bad of  things and you can also solve your doubts over discussions. 

Conclusion

In the end, to become a pro in Java, one needs to be updated and know the latest language features, adopt every aspect of this language, and do self-practice on it as well. There are lots of courses going around for this language, choose according to your way and learn new things every now and then in this year of 2024. Explore options like the Java course in Indore, Delhi, Agra, Gurgaon, and other nearest cities to enhance your skills effectively.
