如何读取文本文件中每行的最后一位数字？

Question

I am making a program that reads data in text files. I also need to know the last number of each line in that file. I was wondering if there is a simply way of doing this.

text file example:

Name: Bob DOB: 1995-04-11 ID: 1

Name: Bill DOB: 1992-07-12 ID: 2

Answer 1

尝试使用以下一种衬垫：

Files.lines(path).forEach(s -> System.out.println(s.charAt(s.length() - 1)));
