Let us look at the overview of Java and its features; and what certifications are best for learning Java.

What is Java?

Released in 1995 by Sun Microsystems, Java is a cross-platform, class-based, object-oriented programming language. Different applications such as games, social media applications, video and audio applications, etc

Java is free to access and can run on all the platforms. It is an independent programming language which means that you don’t need to write the code again and again for executing it on different machines. In other words, you can “Write Once, Run Anywhere” and the compiled code can be executed on all the platforms that support Java.

So, Java is a computing platform that can be used for developing applications.

A Java Developer is a professional responsible for writing powerful Java codes to design and build applications along with integrating the front-end to the back-end.

Features of Java

Object-oriented

Java is an object-oriented programming language, which means it is based on the concept of "objects" that represent data and the methods that operate on that data. This makes it easy to design and structure complex programs using a modular approach.

Platform-independent

Java is designed to be platform-independent, which means it can run on any device or operating system that has a Java runtime environment (JRE) installed. This makes it easy to write code that can be run on multiple platforms without the need to rewrite or recompile the code.

Simple

Java is designed to be easy to learn and use, with a syntax that is similar to other popular programming languages like C++ and C#. It includes a large number of built-in libraries and tools that make it easy to develop applications quickly.

Secure

Java is known for its security features, which make it a good choice for building applications that handle sensitive data or run in a networked environment. It includes features like automatic memory management, which helps to prevent common security vulnerabilities like buffer overflows.

Robust

Java is designed to be robust, meaning it is resistant to errors and can handle unexpected input and conditions without crashing. It includes features like exception handling, which allows developers to handle and recover from errors in a controlled way.

Multithreaded

Java supports multithreading, which means it can run multiple threads of execution concurrently within a single program. This makes it a good choice for building applications that need to perform multiple tasks at the same time.

High-performance

Java is designed to be efficient and fast, with a Just-In-Time (JIT) compiler that converts Java bytecode into native machine code for faster execution.

Portable

Java is designed to be portable, which means it can be easily moved from one platform to another. This is made possible by the Java Virtual Machine (JVM), which provides a consistent runtime environment on any platform that supports it.

Dynamic

Java is a dynamically-typed language, which means that the type of a variable is determined at runtime rather than being statically defined at the point of declaration. This allows for more flexibility in program design, but can also make it more challenging to debug.

Extensible

Java includes a large number of libraries and frameworks that can be used to build a wide range of applications, and it is also extensible, which means you can add your own custom libraries and components to the Java runtime environment. This makes it a good choice for building complex, feature-rich applications.
