Without knowing the types involved it'll be something like this:
for (Map.Entry entry : List) {
System.out.println(entry.getKey());
System.out.println(entry.getValue());
}
Update
Based on the new sample the answer is this:
for (Map<Long, String> map : list) {
for (Entry<Long, String> entry : map.entrySet()) {
System.out.println(entry.getKey());
System.out.println(entry.getValue());
}
}
