I am quite new to Java and would like to learn Java using an interactive shell, like I did with Python using IPython.
I have tried a few interactive shells, such as beanshell, jython, jythonconsole, and JyConsole. Most of them don't have tab completion like IPython does. Is there anything similar to IPython for java?
You probably won't get much use out of using java interactively, as that language is strongly oriented toward compiling. The best route will probably just get a nice IDE, like eclipse, and get started with breakpoints and the debugger.
Gayan Weerakutti already mentioned in a comment what I think should be the correct answer, too:
JShell is part of the JDK since version 9.
Try jshell on your terminal.
Check out docs from Oracle about it.
I think I find a good enough alternative: JPype. JPype allows python programs having full access to java class libraries. With JPype and IPython, I can use all java functions while having very nice tab completion for the java classes.(After the class is imported though)
IntelliJ IDEA has a groovy console with tab completion.
open it: Tools -> Groovy Console...
