A HashMap allows for efficient lookup of student information using their name or some other unique identifier as the key. This way, it is easy to test if a student is in the soccer team and retrieve their information. Additionally, a HashMap allows for the storage of key-value pairs, making it easy to associate each student with their corresponding information. This means that the phone number, address, and age can be stored with each student in the same data structure.
