华为OJ1:字符串翻转

高手勿喷,纯当记笔记

public class Test1 {

/**
* @param args
*/
public static void main(String[] args) {
String s = "I am a boy";
Test test = new Test();
String reverseString = test.reverseString(s);
System.out.println(reverseString);

}

public static class Test{
/**
* 字符串翻转,如"I am a boy",翻转后是"boy a am I"
* @param s
* @return
*/
public String reverseString(String s) {
String[] strings = s.split(" ");
StringBuilder sb = new StringBuilder();
for (int i = strings.length-1; i >=0; i--) {
sb.append(strings[i]);
sb.append(" ");
}
return sb.toString().trim();
}
}

}
