Use of such a set of Java set by a user given information, display information corresponding to the remaining piece of information

| - demand explanation

| - realization of ideas

1, create a class of employees, used as an array of objects, store employee information

2. Create a collection set inside the test class, add an array of objects in the collection inside

3, required input information, based on the information input by the user through the entire collection set, matched to the outputs
