Foreword
Dear Colleagues,
Welcome to the 2023 Java Developer Productivity Report from JRebel by Perforce! Java is one of the most
popular programming languages in the world and is widely used for developing various types of applications,
from web and mobile to desktop and enterprise software. As a Java developer, your skills and expertise are in
high demand just as much as your insights and opinions are valuable for the broader Java community.
Since the inception of this survey in 2012, our aim has been to gain a better understanding of the current state
of the Java development ecosystem — including the tools and technologies used, the challenges developers
face, and the emerging trends that’ll shape the future of Java development. Respondents throughout the
world have helped us gather valuable data to inform our research, as well as provide insightful perspectives
for Java developers, employers, and the overall Java community.
As for the big takeaways for Java in 2023? Java developers continue to be high in demand, which is
encouraging with Java being the programming language of choice for large enterprise applications.
Productivity, particularly in Java development, remains to be a major area of focus as microservice
environments continue to expand both in size and redeploy times. Organizations will keep finding ways to
create innovative Java applications and boost productivity — including adding tools like JRebel.
As product manager of JRebel, this data also helps provide me with a better understanding of what
developers need — whether it’s deciding on a new application architecture or adopting a new IDE —
and how to best tailor our solutions to meet those ever-growing needs. So I hope you find my specific
takeaways on each result insightful and beneficial for your Java initiatives!
We appreciate your time and contribution to this survey and look forward to sharing the results with you. Let’s
get started!
Happy reading,
Curtis Johnson

About the Survey
The 2023 Java Developer Productivity Report is based on a survey of Java
development professionals around the world. The survey, which ran from
November 2022–January 2023, drew a total of 411 responses.
The survey focused primarily on the Java technologies and approaches used
in developing Java applications today. We also included questions specific to
performance issues and microservices, as well as organization firmographics.

Reporting & Analysis Methodology
For the purposes of this report, we omitted any responses representing less than 1% of the total respondents.
We also rounded each value to the nearest full percentage point to simplify analyzing the results. Where
beneficial, we used the organizations’ firmographic data to help form additional insights around the
general data.
Respondent Demographics and
Organization Firmographics
In our first firmographic question, we asked respondents to share the location of their company headquarters.
While this isn’t indicative of where the bulk of a given company’s work is being done (especially with larger
companies), it can help us frame the results of the survey within the context of regionality.
Companies were represented from around the world, but the largest contingents (by country) belonged to
the United States and China.
