Can You Store Multiple Strings in a Java Map?

Storing Multiple Strings in a Map

Question:

Is it feasible to store more than one string value in a Map structure?

Example:

Consider a scenario where you require a Map to store information such as number, name, address, and phone, where each value is associated with the others.

Answer:

While Java's Map interface allows for the storage of key-value pairs, each key can only be associated with a single value. To circumvent this limitation, you should utilize an object-oriented approach.

Instead of using strings as individual keys, create an object that encapsulates the desired information. For instance, you could define a ContactInformation class with properties for number, name, address, and phone. This object can then be stored as the value associated with a single key in the Map.

By leveraging this approach, you can effectively store and retrieve multiple strings as a cohesive unit within a Map structure.
