First, we create an empty map, and insert some elements into it: Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<>(); Java SE 7 TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>(); treeMap.put(10, "ten"); treeMap.put(4, "fou...

First, we create an empty set, and insert some elements into it: Java SE 7 TreeSet<Integer> treeSet = new TreeSet<>(); Java SE 7 TreeSet<Integer> treeSet = new TreeSet<Integer>(); treeSet.add(10); treeSet.add(4); treeSet.add(1); treeSet.add(12); Once we hav...
