Sun Microsystems released the first public implementation as Java 1.0 in 1996.[26] It promised write once, run anywhere (WORA) functionality, providing no-cost run-times on popular platforms. Fairly secure and featuring configurable security, it allowed network- and file-access restrictions. https://deveducation.com/ Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular. J2EE included technologies and APIs for enterprise applications typically run in server environments, while J2ME featured APIs optimized for mobile applications.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically java developer program not available in traditional compiled languages. A Java developer is a specialized programmer who collaborates (working with two or more people) with software engineers and web developers to integrate Java into applications, software, and websites. He is responsible for developing a robust code that can be easily integrated with the larger systems.
Characteristics of Objects in Java
A Java Developer programs, develops and tests Java-based software, applications and websites. Java is an older language, but it remains one of the most popular programming languages due to its versatility. Java developers can be responsible for unit testing the code to check for bugs. Unit testing is a process where software developers look at an application’s individual units of code and make sure they work right. A Java developer might also create test cases to test specific parts of an application, such as the user interface (UI) or the user experience (UX). A test case is a set of steps you take to see how an app will respond under certain circumstances.
As Java is an OOP language, you should understand the four OOP principles and the SOLID principles of OOP development. As many Java developers liaise with IT vendors, you will need good verbal and written communication skills. Ideally, you should also develop your negotiation skills and build rapport with others, making liaising with vendors easier. As you will need to design and build projects from the ground up, you must know how to construct a project’s architecture to be logical, consistent, and extendable long-term.

As a Java developer, you will need to deploy code to deliver it to users successfully. The everyday work life of a Java developer depends on whether you are an entry-level, mid-level, or senior developer. Android does not provide the full Java SE standard library, although the Android SDK does include an independent implementation of a large subset of it.
NET Developer
Java developers implement application designs, diagnosing ineffective processes, and conducting troubleshooting. A Java developer must ensure the stability of the application before launch to provide the best user experience. Software developers must have an excellent command of programming languages, software analysis, system codes, and other technical specifications. A software developer maintains a record of the processes and issues resolutions for reference and improvement opportunities. A senior .NET developer is responsible for creating and managing software applications and programming languages under the .NET framework.
