posure on “Do I Want to Learn Java?”
Don't be mistaken, these companies are already fully aware that they may be more productive in other languages. The issue is that it is too costly for most companies to port existing technologies to new languages due to the large amounts of time and money already invested in Java.
Honestly, I haven't come across many companies that still use Java because it is the best solution; it just isn't feasible to switch either financially or in regards to the time. Some of these companies may have libraries that would take multiple years and millions of dollars to port.
