在Java中将带有双打和字符的字符串转换为双打的最佳方法

Question

如果我已经问了一个已经回答的问题，但我不确定作为初学者的最佳方法，请原谅我。

我有一个类似下面的字符串，转换这个字符串的最佳方法是什么，以便我只有双打 3.4134388041,0.63117288 等，而我丢弃其余的？

谢谢！

以下代码应该隔离字符串中不能被 1 整除的每个数字，分别打印它们：

public static void main(String[] args)
{
    String text = ""; // string was too long to fit here for tidiness
    Matcher search = Pattern.compile("(?!=\\d\\.\\d\\.)([\\d.]+)").matcher(text);
    while (search.find())
    {
        double doub = Double.parseDouble(search.group(1));
        if (doub mod 1 != 0)
        {
            System.out.println(doub);
        }
    }
}
