Java needs no introduction in the world of development. Even if you’re not from a technical background you might have heard Java and its potential to develop a wide variety of technical solutions such as mobile apps, game apps, desktop apps, web apps as well as enterprise software. However, let’s start by dissecting the basic concept of Java before diving into the top Java Developer Skills you should look for when hiring Java Developers.
What is Java?
Java is a high-level object-oriented programming language that runs on the ‘write once, run anywhere’ philosophy. Why is this important for clients looking for dedicated app development solutions? Because write once run anywhere means you only need to code for one platform (Web for instance) and the code would run anywhere – Android, iOS, desktop and other smart platforms with only some minor modifications or tweaking.
This helps you reduce the estimated app development cost significantly while also reducing time to market that enables you to deploy your Java project on the necessary platforms quicker.
Core Java Concepts to Know
Now that we have a basic idea of what Java is and what it can do as a programming language for your business, we can dive a little deeper into understanding some core concepts related to Java. Don’t worry we won’t geek out on you! Knowing these concepts can help you better judge the Java developer profiles that you go through when finding and hiring dedicated Java Developers for your project.
Concept | Description |
Inheritance | Inheritance allows one class to inherit methods and properties from a different class. The one that inherits the properties is called subclass while the one being inherited is known as superclass. |
Polymorphism | This allows objects from different classes to be treated like they belong to the same superclass. This increases code reusability significantly. |
Abstraction | Developers can use abstraction to hide the implementation of any class and only showcase the necessary information for the user. This makes maintenance and code modification much easier. |
Encapsulation | Encapsulation bundles data and methods working on that particular data that resides within a single class. This safeguards the data from being modified from other classes. |
Exception Handling | Exception Handling allows Java developers to manage and handle errors that might show up during program execution. Exceptions are referred to objects that represent errors in the code. These thrown errors can be detected by our experienced Java developers for hire to prevent your Java program from crashing. |
Collections | Collections is a Java based framework that is like a repository of classes and interfaces that help store and manipulate groups of objects. You can set data structures like lists, queues, maps and more using collections. |
Multithreading | One of the biggest benefits and reasons to choose Java for your project, since multithreading allows different threads of execution to run concurrently within a single program. |
File IO | A mechanism that allows Java developers to read from and write to files. It is required for storing and retrieving data from file systems. |
