Java Map With Sorted Keys

22 multimaps.index returns an immutablelistmultimap, so you wouldn't be able to sort it after creating it. As we can see, if we try to insert two values for the same key, the second value will be stored, while the first one will be dropped. The elements are ordered by the keys since it is a sortedmap.

As we can see, if we try to insert two values for the same key, the second value will be stored, while the first one will be dropped. Since the default order for a javascript map object is by order of insertion, we need to write our own code if we want to sort the map by the keys or the values to get a sorted map.

Java map sort by value ascending.

We can sort the map based on its key or value. The entryset () method returns a set of map.entry<k, v> objects that reside in the map. We can sort the map based on its key or value. Now, let's go ahead and sort the unsortedmap, by creating a new linkedhashmap that'll contain the elements, in sorted order.
