Java is a high-level programming language, originally developed by James Gosling at Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s. Java is class-based, object-oriented and designed to have as few implementation dependencies as possible, meaning that Java code can run on any device on which a Java Virtual Machine (JVM) is installed.
Java is widely used to develop desktop, mobile and Web applications. It is also used to develop server-side applications, games and embedded systems. Java has a large community of developers and is known for its robustness, security and cross-platform compatibility.
Java has a rich collection of libraries and APIs that allow developers to easily build applications for different platforms. The Java Development Kit (JDK) is a free software development kit that includes tools for developing, testing and deploying Java applications. Java also has a number of powerful tools for debugging, testing and profiling code, making it a popular choice for software developers and organizations.
Java is an object-oriented, class-based, concurrent programming language designed to have as few implementation dependencies as possible. Java code can run on any platform on which a Java Virtual Machine (JVM) is installed, making it a platform-independent language.
Java programs are created with the Java Development Kit (JDK) and written in .java files. These files are compiled into Java bytecode, which can be executed by the JVM. The JVM is responsible for interpreting the bytecode and executing the program. Java has a large number of libraries and APIs, including the Java Standard Library, which provides access to commonly used functions, such as input/output, network communications and graphical user interfaces.
Java also places a strong emphasis on security, with features such as automatic memory management, type checking, and security features such as access control and encryption. These features make Java a popular choice for developing enterprise, Web and mobile applications.
In short, Java is a powerful and flexible language that provides developers with the means to create powerful and secure applications that can run on a variety of platforms.
To become certified in Java, you usually have to take an exam offered by Oracle, the company that owns and develops the Java programming language. The requirements for taking the exam depend on the specific certification you are pursuing, but generally you must meet certain requirements, such as a certain level of education or experience programming in Java.
Before taking the exam, it is recommended that you take a training course from Oracle so that you have a good understanding of the Java programming language and related technologies. The exams are computer-based and are usually administered in testing centers around the world.
Prerequisites for the exams may include the following:
It is important that you review the requirements for each exam carefully before registering. To best prepare you, we offer several training courses at OEM that will provide you with all the information you need to pass the exam.
Java has become essential technology for companies of all sizes and industries due to its versatility, scalability and security. Java is designed as a platform-independent language that can run on any device or operating system, making it a popular choice for organizations. With its powerful tools, rich libraries and large community of developers, Java can help organizations streamline their processes and improve their overall efficiency.
Java has a wide range of applications, from Web and mobile application development to cloud computing, big data and IoT. With Java, organizations can create complex, high-performance applications that are robust, secure and scalable. The programming language also has a strong reputation for security, which is crucial for companies handling sensitive data or transactions.
One of Java's main advantages is its flexibility, as it can be used to develop a wide range of applications, from desktop and server applications to mobile and Web applications. Java is also known for its scalability, making it an ideal solution for organizations looking to grow and expand their business. Java developers can build applications that can be deployed on a variety of platforms, including Windows, MacOS, Linux and Solaris, as well as on mobile devices such as Android smartphones and tablets.
In addition, Java is a popular choice for organizations seeking cloud computing because it provides a platform for building and deploying cloud-based applications. Java developers can use the language to develop applications that can run on cloud platforms such as Amazon Web Services (AWS), Google Cloud Platform (GCP) and Microsoft Azure.
In short, Java is an essential technology for organizations looking to streamline their processes, improve overall efficiency and stay competitive in today's fast-paced business environment. By investing in Java training and certification, organizations can harness the power of this versatile, scalable and secure technology and realize its full potential.

Java is a popular class-based, object-oriented programming language that has been around since the mid-1990s. It was developed by James Gosling and his team at Sun Microsystems, which was later acquired by Oracle Corporation. Java was created as a solution to the problems of building complex, interactive and portable applications for various devices and platforms.
Java's original goal was to create a platform-independent language that could run anywhere, without the need for recompilation. This goal was achieved through the use of the Java Virtual Machine (JVM), which interprets compiled Java code at runtime into machine-specific code. This makes Java an ideal choice for building applications that can run on multiple platforms, including Windows, macOS and Linux, as well as embedded systems and mobile devices.
First made public in 1996, Java quickly gained popularity as a platform-independent language that could be used to develop high-quality, scalable and reliable applications. Since then, it has become one of the most widely used programming languages in the world, with an extensive ecosystem of libraries, tools and frameworks to support application development.
Over the years, Java has evolved to meet the changing needs of developers and organizations, adding new features, libraries and tools to the platform. Today, Java remains a popular choice for building enterprise-level applications, Web and mobile applications, games and more. With its rich history and continued evolution, Java will remain a major player in the world of software development for years to come.
