It is possible to do the job without integrated development environments (IDEs)—ask people like me who programmed in the olden days. It is not possible to program without essential development tools.
Given that they are central to the task, it’s surprising how rarely people use tools like javac directly. While knowing how to make effective use of an IDE is important, understanding what it is doing, and how, is crucial.
Once upon a time, I worked on a project with two subsystems, one in C++ and the other in Java. C++ programmers worked with their editor of choice and the command line. Java programmers used an IDE. One day, the incantation to interact with the version control system changed. It was a simple command-line change for the C++ programmers, who went on their way without delay.
