So here in 2019, you can expect to earn good and hired as a developer with a good pay scale. If so, then you would prefer some very advancing popular programming language which is Java and Kotlin. These two languages are having benefits in both the case like earning as well as the most demanding career option as per the job postings.
There are several instances where you can replace both of them from each other, as both the languages run on the same underlying platform which is java virtual machine.
This language is an open source, which can be typed statistically and have already gained popularity in the last two years for building some Android apps.
Kotlin has been described by a Netflix senior software engineer as offering some of the best features of other languages combined with interoperability with Java. There is even speculation that it will eventually replace Java for Android development.
Meanwhile, the well paid and reasonably used language is Java, this language is of choice writing serverside business software for more than a decade. Beyond business, Java is also an official language used for developing Android apps and is also used for games and web apps.
Throughout 2018, these languages gained popularity and it is noted by the vacancies of the UK IT job.
According to IT Jobs Watch, the top five languages in terms of earnings in the 12 months to December 2018 were:
The demand for Java is reflected in figures from UK recruitment company Hays, with Java developer being one of the top five highest paying roles throughout 2018 and is expected to increase in 2019.
That said, the higher salaries are reserved for experienced web developers, for example, frontend developers skilled in using UI design frameworks such as Angular and React, and starting salaries for web developers are significantly lower.
Hays Milligan says demand for web frontend and backend skills, alongside Java, had remained a strong year in, year out.
The other languages that offer the highest salaries are Scala, Go and Groovy, as well as the data science and statistical analysis language R. While R is still the most commonly used language by data scientists at work, according to a recent Kaggle survey, there aren't a huge number of postings searching for Scala, Go and Groovy talent, so while they are well-compensated, it may be hard to find related work. Although given Scala is designed to be interoperable with Java, it may also be a good choice to learn alongside that language.
