The senior Java developer positions are highly responsible for project development. Java servlet technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server and for accessing existing business systems. Servlets are server-side Java EE components that generate responses to requests from clients.
The classes in the Java APIs are organized into separate groups called packages. Each package contains a set of related interfaces, classes, subpackages and exceptions. This website is using a security service to protect itself from online attacks.
Q1. What does a Java Developer do?
A small team called ‘The Green Team’ initially conceptualized Java in the early 1990s. That team included James Gosling, who later became known as the ‘Father of Java’ for his work. Gosling developed Java while working as an engineer at Sun Microsystems (a subsidiary of Oracle today). In general, senior web developers earn the most working in the media industry, with an average salary of $116,206.
Prior to the introduction of generics, each variable declaration had to be of a specific type. For container classes, for example, this is a problem because there is no easy way to create a container that accepts only specific types of objects. Either the container operates on all subtypes of a class or interface, usually Object, or a different container class has to be created for each contained class. Generics allow compile-time type checking without having to create many container classes, each containing almost identical code. In addition to enabling more efficient code, certain runtime exceptions are prevented from occurring, by issuing compile-time errors. If Java prevented all runtime type errors (ClassCastExceptions) from occurring, it would be type safe.

They thoroughly analyze user requirements, envision system features, and define application functionality. Besides, a Java Developer also proposes changes to the current Java infrastructure of the legacy applications. As you learn Java, you should also start improving your project management skills. During this step, you should focus on java developer course planning, designing, and building small-scale projects with Java. Managing small projects will help you develop your system architecture and management skills (as well as give you some projects to show potential employers during job interviews). Java is a programming language developers use for mobile, software, and web development.
A senior .NET developer must have strong knowledge of the technology industry and software programming disciplines to assist junior developers and drive strategic results.
