The notation specifies that only String objects may be stored in the ArrayList object. This is known as creating a generic ArrayList, where the type of objects being stored is specified in the angle brackets (<>). In this case, it is ensuring that only String objects can be stored, which helps to avoid type-related errors at compile time.
