JAVA - 쓰레드 예제(2) - 경마프로그램

10마리의 말들이 경주하는 경마 프로그램 작성하기

말은 Horse라는 이름의 클래스로 구성하고,
이 클래스는 말이름(String), 등수(int)를 멤버변수로 갖는다.
그리고, 이 클래스에는 등수를 오름차순으로 처리할 수 있는
기능이 있다.( Comparable 인터페이스 구현)

경기 구간은 1~50구간으로 되어 있다.

경기 중 중간중간에 각 말들의 위치를 >로 나타내시오.
예)
1번말 --->------------------------------------
2번말 ----->----------------------------------
...

오름차순 sort
경기가 끝나면 등수 순으로 출력한다.

스레드로 말 클래스 만들고 전역변수로 발이름, 등수
