URL: https://github.com/apache/kafka/pull/15071
Multiple clean ups for `warn` discovered via automatic tooling (different
ones). No logic change.
Types of clean up:
1. Remove redundant imports
2. Use bulk collection operations such as `putAll` instead of iteration
3. Replace `Arrays.asList()` with `Collections.singletonList()`
4. Remove String concatenation in a loop, use StringBuilder instead
5. Replace `if` with `switch`
6. Use `compare()` to compare integers
7. Loop is replaces with `Collection.removeIf()`
8. Replace StringBuffer with StringBuilder
9. Replace `for` with enhanced `for` loop
10. Replace redundant `Collection.addAll()` with parameterized constructor
call
11. Use `%d` with integers instead of `%s`
12. Replace `String.equals("")` with `String.isEmpty()`
13. Replace `Collections.sort()` with `List.sort()` where applicable
14. Replace `System.getProperty("line.separator")` with
`System.lineSeparator()`
