Today, technology is passing an evolution stage. Every second day, there is some expansion in the development of technological innovations. Java is one of the most commonly used programming languages behind technological innovation.
With Java code being everywhere, people often get confused about different questions regarding Java programming. For example: What are the advantages of Java? What is Java used for? What is the collection in Java? In this blog, we will explore Java’s interesting history.
What is Java?
Java is a general-purpose, class-based, object-oriented, high-level programming language developed in 1995. The basic purpose of Java is to cut off the implementation dependencies. It is a computing program used for application development.
Features of Java Include the Following Features
-
Efficient: Java programming can easily run several programs, simultaneously. Thus, it is an efficient language.
-
Portable: Java is a portable programming language. It runs on the ‘write once, use anywhere’ idea. Programmers can write Java code & use the same on other projects, without the need to begin from scratch.
-
Secure: Java is highly secure because you need to create a code once. The Java code is automatically converted to bytecode. Humans don’t have the efficiency to read bytecodes, which protects programmers’ work from untrusted sources and viruses.
To learn Java, as a beginner, you must have proper knowledge about some of the terms like Object in Java, Collection in Java, and Package in Java. Below, we have briefed each of these terms.
What is an Object in Java?
An object in a Java class is a member, also known as an instance. Java objects can be also defined as the basic unit of Object-Oriented Programming. Every single object in the Java class has an identity, a behavior, and a state. The object represents real-life entities. Java class has variables where every state of an object is stored as fields. Methods also known as functions display the object’s behavior.
What is Collection in Java?
A Collection in Java is a framework. Every java collection has to offer a design to store and manipulate the group of objects. With Java collection, programmers can perform all the operations on data like searching, classifying, insertion, manipulation, and deletion.
Java Collection can also be understood as a single unit of objects. Java Collection framework has many interfaces & classes. Set, List, Queue, and Deque are some of the interfaces, and ArrayList, Vector, LinkedList, PriorityQueue, and HashSeta are some of the classes.
What is a Package in Java?
A package can be defined as a group of classes, sub-packages, and interfaces. Java package helps organize and maintain existing classes into a folder structure. Packages in java are quite helpful for programmers as they make it easier to find and utilize folders & reuse Java code.
How to Get Started with Learning Java?
To learn Java online, you have to be familiar with some of the basic programming concepts. First and foremost, try mastering data structures (array, Stack, Queue, Tree, Graph). You can then go learn concepts like operations, conditions, collection, loops, and getting user inputs.
You should also enroll in online java tutorials to learn basic algorithms like binary search, linear search, bucket sort, quick sort, etc. Once you have spent a lot of time learning programming concepts, it’s time to understand the foundational OOP concepts. Object Oriented Programming concepts like Polymorphism, encapsulation, inheritance, and abstraction, form the basis of Java. Thus, learning them is highly beneficial.
It is Java an object-oriented programming language & you are a beginner. So, you should practice using an IDE (Integrated Development Environment). Don’t spend all your time and effort just reading theory. Try writing codes. You can begin with simple program coding quite early.
At a vaster level, Java programming concepts include file handling, database connection, exception handling, threads, generics, garbage collection, and pattern designing. You have to gain expertise with all of these concepts. Also, try creating projects and web services.
NOTE: If you find books interesting, browse on Amazon and find Java books. Thinking in Java (3rd edition), The Java Language Specification, Java SE 8, The Java Tutorials, and Think Java (How to Think Like a Computer Scientist) are a few best Java books for beginners.
