Wow! The above facts are potent enough to tell you how valuable a Java Certification can be for giving a boost to your career.
Let us look at the overview of Java and its features; and what certifications are best for learning 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

This is the most basic Java certification offered by Oracle which covers the basic concepts of Java. This makes your grip over Java strong and enhances your programming skills. This certification validates your skills to become an expert Java developer.
This is a professional level certification that demonstrates your knowledge and expertise in code development in Java SE 8. If you have professional experience in Java, going with this certification is best for you.
You can take this exam after passing OCAJP as it is needed to validate that you have the necessary skills required for becoming a master Java developer.
The Oracle Certified Professional Java EE 7 Application Developer demonstrates that you can develop and deploy the applications by utilizing Java Enterprise Edition 7. This certification is ideal for you if you are a software engineer, a solutions architect, or a Java frontend and backend developer with intermediate to advanced level expertise in using Java EE 7.
This is the same as OCAJP certification with the difference that it is for Java Standard Edition 11.
