Skills of best java developers
Knowledge in OOP
Object-Oriented Programming (OOP) is vital when you decide to hire dedicated Java developers. A professional Java developer should strongly understand OOP concepts and principles. Some of which are encapsulation, inheritance, and polymorphism. It helps skillful java developers write high-quality modular, reusable, and maintainable code. The projects also benefit as OOP and developers can enhance code organization, readability, and scalable Java applications.
A strong grasp of serialization and abstract classes
It is complementary to hire java developer that understand processing data such as elements, methods. Because serialization in Java involves transferring an object from one system to another and transform the object into a stream of bytes to restore it to its original format. Serialization in Java may look very simple at first, but it comes along with some trivial security and integrity issues that your application must take in seriously. Similarity, to implement abstract Java with accordingly notice is also a simple but must-have skills of a Java developer.
Database Management
According to Turing, Java developers should have knowledge of databases as it allows them to efficiently handle data storage, retrieval, and manipulation in application. Understanding databases enables developers to design optimized data models, execute database queries, ensure data integrity, and implement efficient data access patterns. The popular database technologies for Java developers are MongoDB, Oracle, MySQL, and SQL Server.
Expertise in Java frameworks
A framework contains pre-built code that serves as a template to build an application or website. In other words, Java framework is the foundation from where Java developers build their software in the corresponding language. Frameworks are typically associated with a specific programming language and are suited to different types of tasks. The best frameworks include Grails, Google Web Toolkit, Spring, MVC, Play, and more. Before hiring Java developer, make sure you mention the required framework in Job description and check the applicant’s expertise with the framework.
Expertise in wireframes and design patterns
Java is widely used to create reliable web applications for multiple purposes and in wide range of domains from healthcare to e-Commerce. Java is also one of most used programming language for front-end development, so that a Java developer must be familiar with Wireframes, UI design, and design patterns.
So when you hire dedicated Java developers, you should note their efficiency to read and understand designs, user flows, and prototypes from UI/UX specialists. This reduces the number of personnel working on the project (and therefore overall cost), helps the product have unified documentation and plays an important role in matching requirements from Business Analyst and stakeholders.
Competency in teamwork and soft skills

So Spring Boot Developer is common types of hiring Java developer based on their tech stacks.
Hibernate Developer
Hibernate is a free-of-charge that allows high-level object handling functions, mapping Java to SQL data type and additional query of data. It saves Java developers time and effort of manually object processing and conversion. So that businesses often hire Hibernate developers to integrate their application to SQL databases or included as a feature of Java/JavaEE programming language. Our best Hibernate developers have solid experience in SQL, JPA and optimization to work with multiple databases.

Sometimes, business also looks to hire Fullstack developers for website projects which is under pressure.
Java Backend Developer
Java Backend Developer offers expertise in designing, developing, and maintaining backend systems and applications using Java programming language. You can hire Java Backend Developer to handle data processing, server-side logic, and API integration, ensuring system scalability, performance, and reliability. On the other hand, we also have the type of hiring Front End Developer for web and mobile application development.
Experience
Junior Java Developer:
This technique of verification is mainly focus on the experience of the applicant. The number of years of experience and development options of developers through those years can prove their capabilities in the long term, and whether they are sustainable enough for your project or not. Experienced developers also have better soft skills but may demonstrate less flexibility. Junior Java Developer has 1-3 years of experience and is to hire for projects that may at least have 2-3 other developers.
Pre-senior Java Developer:
Pre-senior Java Developer have from 3-4 years of experience in software development. You can hire java developer with 3-4 years of experience in smaller projects with the developer as the atom of the application development as with previous experience, they can handle larger workload and multiple tasks.
Senior Java Developer:
Hiring java developer from 6-7 years up of experience is categorized as hiring senior Java Developer. They often have in-depth experience in a certain field of Java programming and can mentor other junior Java developers. Therefore, the cost for hiring a senior java developer will also be 2 to 3 times higher than for junior ones.
Java Solution Architecture:
These are people who not only have basic programming knowledge, but they can also advise and support other roles of the team to come up with a complete strategy. They can perform, design, select, and align appropriate development resources. Therefore, they are often the technical leader or team lead of a large Java development project. They have at least 10-13 years in the IT field in general and usually 6-7 years in Java developing.
