Java Program To Print The Golf Scoreboard : Any Number Of Players

Golf  is one of the niche game . In this program ,  we  print  the scoreboard for all the golfers taking part in the tournament , and also printing out the  winner of the tournament with the least number of strokes to complete all the 18  holes  in 4 days competition .

It is one of the coolest program , as we just need to submit the number of players and player scores in the text , thats it .

About Golf : Golf has 18 holes with each hole has certain minimum number of strokes to play for known as PAR score . Player has to complete all holes each day and this is a 4 day competition .

For this program we are assuming the following stats :\

GolfScore.txt

The first line contains the total number of players in the competition

Rest lines contain the score of each player corresponding to that hole .

As there are 18 holes in the game , so GolfScore.txt  contains total 19 lines .

Course.txt

It contains the PAR score of each hole

One line represents the PAR value of one hole .

It contains total of 18 lines as there are 18 holes in the game of golf .
