Comparators are used to compare two objects. In this challenge, you'll create a comparator and use it to sort an array.
The Player class is provided for you in your editor. It has [SVG image] fields: a [SVG image] String and a [SVG image] integer.
Given an array of [SVG image] Player objects, write a comparator that sorts them in order of decreasing score; if [SVG image] or more players have the same score, sort those players alphabetically by name. To do this, you must create a Checker class that implements the Comparator interface, then write an int compare(Player a, Player b) method implementing the Comparator.compare(T o1, T o2) method.
Input Format
Input from stdin is handled by the locked stub code in the Solution class.
The first line contains an integer, [SVG image] , denoting the number of players.
Each of the [SVG image] subsequent lines contains a player's [SVG image] and [SVG image] , respectively.
Constraints
- [SVG image]
- [SVG image] players can have the same name.
- Player names consist of lowercase English letters. Output Format
You are not responsible for printing any output to stdout. The locked stub code in Solution will create a Checker object, use it to sort the Player array, and print each sorted element.
