Looping Map In Java

We know that the keyset () method returns a set view of the keys contained in the map. Most efficient way to iterate map: Using an iterator to iterate through a hashmap.

Looping Map In Java In this program, we have accessed all the keys of linkedhashmap using keyset () method and then iterated all the keys using enhanced for loop and accessed value by passing key in each iteration in the loop.

Using a foreach to iterate through a hashmap. Iterating is very common process in any programming language using very basic for loop. Alternatively, we can first get all keys in our map using the keyset method and then iterate through the map by each key: Browse other questions tagged java loops hashmap iterator initialization or ask your own question.
