What is the signature of a Map method that adds a key-value pair to the Map?
Final Answer: The signature of a Map method that adds a key-value pair to the Map is b) void put(K key, V value).
Explanation: The signature of a Map method that adds a key-value pair to the Map is represented by option b) void put(K key, V value). The "put" method is commonly used in Map implementations to associate the specified value with the specified key in the map.
Understanding the "put" Method in Map
Key-Value Pair Addition: In Java programming and other languages utilizing Map data structures, the "put" method plays a crucial role in adding key-value pairs to the Map. The signature of the method, which is void put(K key, V value), signifies that it does not return a value.
The Purpose of "put": When developers use the "put" method, they are essentially inserting or updating the key-value pair within the Map. This operation allows them to store information or data associated with a specific key.
Parameter Explanation: The method takes two parameters - the key (K) and the corresponding value (V). By providing these inputs, developers can establish a relationship between the key and the relevant data stored in the Map.
Essential Operation: "put" is a fundamental operation for manipulating Map data structures. It enables developers to add, update, or overwrite key-value pairs based on the specified key, making it a versatile tool for managing information.
Summary: In conclusion, the signature b) void put(K key, V value) accurately represents the method used to add a key-value pair to a Map. By understanding how the "put" method functions, developers can effectively work with Map collections and efficiently manage data relationships.
