I have a method which is returning List<Map<String,Object>>.
How to iterate over a list like List<Map<String,Object>>?

Iterating over Map. Entry<K, V>>) of the mappings contained in this map. So we can iterate over key-value pair using getKey() and getValue() methods of Map. Entry<K, V>. This method is most common and should be used if you need both map keys and values in the loop.
Obtain an iterator to the start of the collection by calling the collection's iterator() method. Set up a loop that makes a call to hasNext(). Have the loop iterate as long as hasNext() returns true. Within the loop, obtain each element by calling next().
You can loop through the list items by using a while loop. Use the len() function to determine the length of the list, then start at 0 and loop your way through the list items by referring to their indexes. Remember to increase the index by 1 after each iteration.
It sounds like you're looking for something like this:
List<Map<String, Object>> list; // this is what you have already
for (Map<String, Object> map : list) {
for (Map.Entry<String, Object> entry : map.entrySet()) {
String key = entry.getKey();
Object value = entry.getValue();
}
}
List<Map<String, Object>> list = getMyMap();
for (Map<String, Object> map : list) {
for (Map.Entry<String, Object> entry : map.entrySet()) {
System.out.println(entry.getKey() + " - " + entry.getValue());
}
}
