Will Java Developers Still Be In Demand in 2023?

I came across this question while doing a Google search:

java-2023-quora-question

The answer to this question is...

YES!

The demand for Java Developers has never gone down.

Java is one of the most in-demand programming languages.

I've worked with Java since 2019, and its demand (in my humble opinion) has never gone down.

There's this belief that only major companies and banks (such as Goldman Sachs, Citi Bank, JP Morgan, etc.) use Java. But this is far from true.

I had several interviews with early-stage startups having Java as their core programming language.

So no, as much as Java gets a lot of hate, the demand for Java Developers remains high.

What Skills Do You Need to Become a Java Developer?

1. Core Java

Spring Boot is a backend framework written in Java which is essentially made to create REST APIs.

Many companies use this framework to support their backends, making learning the framework worthwhile.

4. SQL

SQL stands for Structured Query Language. It's a language used for relational database management systems.

Java Developers are substantially backend developers. Therefore you will deal with data manipulation, and learning SQL is worth your time.

5. Cloud Computing

I'm yet to find a company that doesn't use a cloud provider.

Knowledge about the cloud is hugely appreciated.

The most popular cloud provider are AWS, Azure and Google Cloud Platform. Knowing any one of these will make you stand out from the crowd.
