Program Specifications

Player.java

The Player class should include fields for the player’s username (String) and current score(int).
The class should set the username field in the constructor using an argument passed to the constructor.
The class should have a setter for the current score field.

Write a method named printPlayerArray() that takes an array of Players as an argument and prints the contents of the array using the Player class’ toString() method.
Write a method named uniquePlayers() that takes an array of Players as an argument and returns a new array of Players where no two Player objects in the array are equal.

Create 4 Player objects with the following data
- username: alice, current score: 50
- username: deathgrip; current score: 99
- username: puddles; current score: 21
- username: alice; current score: 67
Add the 4 Player objects to an array of Players.
Retrieve an array of unique Player objects by calling uniquePlayers().
Sort the array of unique Players with the sort(Object[] a) method in the Arrays class.
Print out the sorted array of unique Player objects.
Print to the screen “Thank you professor for helping me be a better programmer”.
