number of segments in a string

admin 11月 13, 2020 0

Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.

Please note that the string does not contain any non-printable characters.

Example:

1 2	Input: "Hello, my name is John" Output: 5

Solution

class  {
    public int countSegments(String s) {
        String[] str = s.trim().split(" ");
        int re = str.length;
        for(int i=0; i<str.length; i++) {
            if("".equals(str[i])) {
                re--;
            }
        }
        return re;
    }
}
