Answered by : wolf-in-penguinmug
/*Suppose a map*/
Map<T> map = new HashMap<>();
/*Insert 2 keys, and remove one*/
map.put('First', 'John');
map.put('Second', 'Tommy');
// Returns a value, you don't have to save it if you want
String removedValue = map.remove('First');Source : | Last Update : Tue, 03 May 22
