A Core Java Developer is responsible for developing and providing efficient, reliable, extensible and maintainable Java-based applications for multiple departments within an organization. This position requires a strong knowledge of object-oriented design patterns and algorithms, as well as a thorough understanding of the Java language, libraries, APIs and frameworks. A successful candidate will be organized and detail-oriented, have strong problem solving and communication skills, and be able to learn quickly and work independently or collaboratively. Job Responsibilities: • Develop high quality, bug-free applications in Java • Designing, developing, testing and enhancing software applications • Maintaining existing applications and fixing bugs • Participating in software architecture design and development • Writing well-designed, testable code • Assisting with user acceptance testing (UAT) • Collaborate with cross-functional teams to define and solve complex problems • Troubleshooting and debugging applications • Documentation of applications and processes

Connector in Java EE stands for Java Database Connectivity (JDBC), which is a set of Java APIs that are used to connect to databases. It allows Java applications to access and manipulate data in a relational database. It also provides a common interface that enables developers to write code that can be used across a variety of databases without having to write different code for each database type.

1. Improved Security: Java EE application servers provide a secure environment for application deployment. They restrict access to unauthorized users and prevent hackers from gaining access to confidential data. 2. Flexible Deployment Options: Java EE application servers are more flexible than traditional web servers and provide the option of deploying applications locally, on-premises, or in the cloud. 3. Stable Platform: Java EE application servers are highly reliable and stable, offering reduced risk of application crashes due to hardware and software failures. 4. Scalability: Java EE application servers are designed to scale easily to meet the demands of small, medium, and large-scale enterprise applications. 5. Performance: Highly optimized for multitasking and multithreading, Java EE application servers offer improved performance and better database integration than traditional web servers. 6. Integration and Connectivity: Java EE application servers support a wide range of protocols and services, making it easier to integrate applications with back-end systems and services. 7. Maneuverability and Maintenance: Java EE application servers come with a set of tools and utilities, which makes maintenance and administration easier. The configurable, modular platform allows users to make changes easily.

The Java Platform, Enterprise Edition (Java EE) is an application platform for developing and deploying enterprise-level applications. Java EE provides an environment for Java-based application development that is both secure and reliable, which makes it suitable for a range of scenarios including web-based applications, mobile applications, and distributed enterprise applications. Java EE provides the framework and tools necessary for developers to rapidly build robust enterprise-level solutions.

There are four major editions of the Java platform: - Java Standard Edition (SE): Used for standalone applications. - Java Enterprise Edition (EE): Used for large-scale, multi-tier, and distributed applications. - Java Micro Edition (ME): Used for embedded, resource-constrained devices. - JavaFX: Used for creating user interfaces and rich internet applications (RIAs).

The Java security model is designed to protect users from malicious or untrusted code. It is based on four key components: the Java sandbox, the class loader hierarchy, access control, and code signing. The Java sandbox is the basis of the security model. It is a tightly regulated environment within the JVM that restricts the code’s access to system resources. The sandbox prevents untrusted code from making dangerous or unauthorized changes to the system, such as changing a system file or accessing the user’s private data. The classloader hierarchy is one of the fundamental security mechanisms in Java. It determines how and where code is loaded into the JVM. The classloader is responsible for enforcing access control, so that only code from trusted sources is allowed to execute. Access control defines who can access a particular resource. Java implements fine-grained access control through the use of the security policy and security manager. The security policy defines which permissions each codebase or user has, and the security manager enforces these rules. Finally, code signing is used to ensure that code is not modified or tampered with after it has been signed. Java developers can sign their code, so that users can verify that it has not been modified or altered.

You can change the security settings of Java by accessing the Java Control Panel from your computer. To access the Java Control Panel, open the Start menu and search for "Java Control Panel." Once opened, you can navigate to the Security tab and make changes to the Java Security settings, such as setting the Security Level and enabling or disabling the Java plug-in.

1. Easy to Learn: Java is an easy language to learn and use, making it a popular choice for Android app development. 2. Object-Oriented: Java is an object-oriented programming language, which allows developers to create modular programs and reusable code, as well as specialize code to specific personal or business needs. 3. Platform Independent: Java programs are able to run on all platforms that support Java without needing to be recompiled, making it a great choice of language. 4. Speed and performance: Java is faster than other languages when it comes to Android development, as it is compiled to byte code that can run on any Java Virtual Machine (JVM). 5. Security: Java is well-known for its security features and is often favored for its ability to protect user data from malicious activities. 6. Extensibility: Java supports the development of new functionalities through the use of XML, databases, and web services. 7. Multi-Threading: Java supports multi-threaded programming, meaning that developers can create applications that can carry out multiple tasks at once. 8. Open Source: Java is an open source platform that is freely available, allowing developers to download and use the language without having to pay any license fee.
