If the character is encountered for the first time, we initialize its count to 1; otherwise, we increment the existing count by 1.Finally, we verify that thecharCountmap correctly stores the count of the character ‘a‘ as 3. 3. Using JavaStreams Alternatively, we can utilize JavaStreamsto...

In this tutorial, we’ll explore how to create a HashMap containing the character count of a given string in Java. 2. Using Traditional Looping One of the simplest methods to create a HashMap with a string’s character count is traditional looping. In this approach, we iterate through each...
