Hire Java Developers in Vietnam

There is a large community of Java developers in Vietnam. This article talks in detail in case you are thinking to hire Java developers in Vietnam.

Introduction to Java

Java is a general purpose language that was designed to work across platforms and be easy to learn. It shares a lot in common with C++ and has been very influential in other languages like PHP, Javascript and Python.

Java is common in desktop, web and Android applications. It can also be found in embedded software, robotics and Big Data. As a result, Java is found everywhere, including huge platforms like Amazon, Ebay and Twitter.

The Java programming language has many strengths:

Java is intended to be WORA (write once, run anywhere). This is achieved by compiling into an intermediate language called bytecode, which runs in the Java Virtual Machine (JVM). This allows applications written in Java to be platform-independent.
This is a multi-paradigm programming language, that can support functional, procedural and object-oriented programming.
Java is multi-threaded, allowing tasks to be completed simultaneously.
It supports stack allocation of memory, providing another option to heap allocation. This has speed benefits.
Java has security benefits, as it reduces the likelihood of mistakes that lead to security flaws.

Note that other languages will run in the Java Virtual Machine and it has been suggested that Java’s importance will decline. However, despite the emergence of Kotlin, Scala and others, Java remains a very popular programming language. Java frameworks, libraries and the ecosystem will remain well into the future.

What does a Java Developer do and know?

Java developers are responsible for the development and management of Java-based applications. Their responsibilities will be related to development, testing, deployment, maintenance and improvement. More experienced Java developers may also have input into architecture or project management.

Java developers should be strong in Java and several web frameworks (such as JSP, JSF, SpringMVC, Struts or Servlets). They’ll also have experience in DI frameworks like Spring, and ORM frameworks like Hibernate. They should be familiar with relational and non-relational databases. Related infrastructure technologies (such as ElasticSearch, Redis) are also important for effective searching, caching, logging and other functions. A range of DevOps tools are also useful.

Fullstack Java developers will also have knowledge of HTML, CSS and Javascript. They’ll be able to build an application using Java and other associated technologies.
