java实现单词逆序输出

实现英文语句的逆序反转

public class Test {
public static void main(String[] args) {
String src = "Hello Java Hello China";
String[] arr = src.split(" ");
int length = arr.length;
StringBuilder sb = new StringBuilder();
for (int i = length - 1; i >= 1; i--) {
sb.append(arr[i] + " ");
}
sb.append(arr[0]);//最后一个单词不加空格
System.out.println(sb.toString());
}
}
