public class Solution { public String ReverseSentence(String str) {
//特殊情况
if(str == "") return"";
//一般情况
//按照空格分隔字符串
String[] strSpilt = str.split(" ");
String result = "";
for(int i = 0; i < strSpilt.length - 1; i++){
//按顺序拼好从开始到倒数第二个字符串
result += strSpilt[strSpilt.length - i - 1] + " ";
}
//最后一个字符串较为特殊，后面无需跟空格，单独处理
result += strSpilt[0];
return result;
}
