[java] minor performance improvements and code cleanup (#14054)
* replaced empty string comparison with isEmpty() invoking * replaced manual array copy with System.arraycopy() * replaced redundant String.format invoking with printf() * replaced deprecated setScriptTimeout with scriptTimeout according to instruction "Use scriptTimeout(Duration)" * replaced iterators with bulk methods invoking * replaced list creations with List.of() * there is no need to create mutable lists in tests to only get elements --------- Co-authored-by: Puja Jagani <[email protected]>
