java根据多空格或tab进行字符串分割

    public static void main(String[] args) {
        String text = "d  sdfsd   dddd  g sdfsd";
        String[] split = text.split("\\s+");
        StringJoiner joiner = new StringJoiner("-");
        for (String s : split) {
            joiner.add(s);
        }
        System.out.println("正确方式："+joiner.toString());

        StringJoiner joiner2 = new StringJoiner("-");
        String[] s = text.split(" ");
        for (String s1 : s) {
            joiner2.add(s1);
        }
        System.out.println("错误方式："+joiner2.toString());
    }
