You can get autocomplete for Java methods in Cider (Emacs) and probably Cursive (Intellij) afaik. Type checking in intro code can be a bit difficult, but REPL/live development really helps. You are going to catch mismatched type at first call, so you can usually get there by reading the Javadoc, but it does take some practice. Most Clojure code also works with Java through the smallest interface possible at the edge of your system, so it is very rare to have to deal with those issues in your "main" code.
