Notes

In Apex, the put(key, value) method is used with a Map to add or update an entry in the map. This method takes two parameters: the key and the value. If the specified key already exists in the map, the associated value is updated; otherwise, a new entry is added.

Here's an example:

Map<String, Integer> myMap = new Map<String, Integer>();

myMap.put('apple', 5);
myMap.put('banana', 3);
myMap.put('cherry', 8);

System.debug('Map after put operations: ' + myMap);

Output: Map after put operations: {apple=5, banana=3, cherry=8}
