Problem

7.3 Object and equals — capstone: find the duplicate

Write a complete program with a class Student that overrides equals (two students are equal when their names match) and toString (returns the name).

Read a count and that many names. Keep only the first occurrence of each, then print the list and how many duplicates were rejected.

For 5 then Ada Sam Ada Bo Sam:

[Ada, Sam, Bo]
2

Use list.contains(...) — it works only because you overrode equals.
