A constructor with a single argument of type SortedMap, which creates a new sorted map with the same key-value mappings and the same ordering as the input sorted map. Note: several methods return submaps with restricted key ranges.
Learn how to use the SortedMap interface of the Java collections framework to sort keys in a map. See examples of methods, such as comparator, firstKey, lastKey, headMap, tailMap and subMap.
Learn how to use SortedMap, a Map that maintains its entries in ascending order, sorted by keys' natural ordering or Comparator. See the operations, constructors, and examples of SortedMap interface and its implementations.
Syntax. Following is the syntax to create a sortemap instance: // Create a sorted map SortedMap<String, Double> map = new TreeMap<>(); Here we're creating a sorted map of String vs Double values. This map will store the keys based on alphanumeric order. Adding Value to a SortedMap.
