Now, let’s suppose we want to iterate over all pairs of values using higher-order functions as foreach, map, and reduce. For instance, this method will receive each pair as a Tuple2. Therefore, we can treat it in two different ways. 3.1. Raw Tuples When iterating, we can treat th...
The lambda expression takes a single parameter named entry, which represents each key-value pair in the map, and prints them to the console using the System.out.println() statement in the format “key : value”.I hope this short Java tutorial with code examples on how to iterate over a ...
Iterate over list in java Read more → Print Array list in java Read more → To see this behavior in action, we will create an implementation that throws a ConcurrentModificationException and then implement different ways to solve the problem. Create a method named removeItems() that accepts...
map.remove(str); } } } } but it will fail and throw java.util.ConcurrentModificationException. So How can I modify the map when iterating it. I want to know a convenient method which do not need many codes. Thanks Aurelian Tutuianu Ranch Hand Posts: 86 posted 15 years ago ...

Using the retainAll method to get the intersection of sets from the keySet method of the Map interface to get the set of keys for both map1 and map2 can avoid iteration over entire keySet. Are you willing to submit PR? Yes I am willing to submit a PR! mvadharia added the enhancement...

This could come in handy in scenarios where you want to perform some operations on data within a map. By using the entrySet() method – which returns a list – it is possible to have an iterator over a map. See the following example to understand how this works: import java.util.*; ...
