What are the equivalents of CodeHunt for Java?

Question

Java

Hello. I liked CodeHunt , but progress is not saved there, and everything goes through the new one - reluctance (and it's not always possible to do it all at once). Maybe there are some analogues of this service (also in Java)?
It is necessary that it was also possible to solve small problems in Java in the browser.
PS It seems that I used to find the names of such services somewhere, but now I can’t find them.
