For Each On Hashmap

Loop through a hashmap using stream api. Allows only unique keys to be stored. Yourhashmap.entryset()) { system.out.println(entry.getkey() + = + entry.getvalue());

Entry is an inner class in whatever map implementation we are using (here, in this case it's hashmap). In the above example, we have used hashmap.entry(). Iterate through hashmap keyset using iterator.

Yourhashmap.entryset()) { system.out.println(entry.getkey() + = + entry.getvalue());

There is a numerous number of ways to iterate over hashmap of which 5 are listed as below: In the above example, we have used hashmap.entry(). First, get all the keys of the map using the keyset method and then iterate over them one by one using the enhanced for loop as given in the below example. Hashmap<string, hashmap> selects = new hashmap<string, hashmap>();
