[HackerRank](4)Java End-of-file

問題網址:https://www.hackerrank.com/challenges/java-end-of-file/problem

問題重點：

Scanner.hasNext() 　Returns true if this scanner has another token in its input.

Scanner.hasNextLine() 　Returns true if there is another line in the input of this scanner.

while(boolean)迴圈使用

因hasNext最後一行為false故不進迴圈，再加印一個最後一行。
