summaryThis article on the analysis of TreeMap a little bit more than the previous articles, treemap with no hashmap so much. We have a macro to compare me and compare it.1, TreeMap is based on key to sort, its ordering and positioning need to rely on the comparison or overwrite comparable interface. It also eliminates the need for key to overwrite the Hashcode method and the Equals method to eliminate the repeated key. The key of HashMap is to ensure that there are no repeated keys by coverin
