Posted 2020-08-22 华裳绕指柔

 

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

For example,

Input: "Hello, my name is John"

Output: 5

    public int countSegments(String s) {
        String trimmed = s.trim();
        if (trimmed.length() == 0)
            return 0;
        else
            return trimmed.split("\\s+").length;
    }
