I've been looking for an online data structures course in Java, but I haven't really found anything suitable... I'm trying to look for a course or a combination of courses that cover the following: selection, insertion, merge, quick, and heap sorts; arrays, array lists, linked lists, stacks, queues, trees, sets, maps, and graphs; recursion, the Java Collections framework, Big-O analysis. I've looked at the MIT OCW course, but it's more advanced than I need, and doesn't really provide enough programming practice, just theoretical problems. Can anyone recommend a good online course/ combo of courses that would cover the above in Java? I've been looking for some time now, and I haven't really found anything good... Thanks for any help (I don't know if this changes anything, but I'm not a complete beginner to java, I just haven't implemented/learned data structures )

Edit: I know I can just look up these topics individually, which is what I would do ideally, but I was hoping for an actual course, because unfortunately, my school requires an actual course for credit...

EDIT 2: I've been looking at this course on Udemy: https://www.udemy.com/introduction-to-data-structures-algorithms-in-java/ BUT my concern was that it didnt have enough assignments and sort of skimmed over things. Do you think I should take this course/ can you recommend something supplementary?

Edit 3: Like could someone recommend somewhere that just has a bunch of good exercises concerning the concepts above?
