题目描述
Given a string s consists of upper/lower-case alphabets and empty space characters ' ', return the length of last word in the string.
If the last word does not exist, return 0.
Note: A word is defined as a character sequence consists of non-space characters only.
Example:
Input: "Hello World"
Output: 5
我的Code如下：
class Solution {
public int lengthOfLastWord(String s) {
if(s.equals("")){
return 0;
}
//这里稍微注意下：如果s="hello",那么分割后strs的长度为1；
//如果s=" "，那么分割后strs的长度为0；
String[] strs = s.split(" ");
if(strs.length == 0){
return 0;
}
return strs[strs.length - 1].length();
}
}
