java - 如何提取正确的字符串？

Question

我有一个像这样的字符串:

 14.809180,56.876968,0.000000 14.808170,56.877048,0.000000 14.805100,56.877220,0.000000 14.804130,56.877338,0.000000

即，开头有一个空格，0.000000 之后也有一个空格。我只想提取 14.XYZ 和 56.XYZ。我怎样才能做到这一点？

Answer 1

根据我的评论，尝试 String#split(...)，例如:

  String test = "14.809180,56.876968,0.000000 14.808170,56.877048,0.000000 14.805100,56.877220,0.000000";
  String[] tokens = test.split("[,\\s]+");
  for (String token : tokens) {
     System.out.println(token);
  }

"[,\\s]+" 是一种正则表达式，可帮助 split 方法使用一个或多个空白字符 (\s) 或逗号分割字符串。
