把一个字符串倒着输入java代码实现

public class reverseString {
public String reversestring(String iniString)
{ char str[]=iniString.toCharArray();
String s="";
for (int i =str.length-1; i>=0; i--) {
s=s+str[i];

}

return s;
｝

}

public class test {

public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner scanner=new Scanner(System.in);
String a=scanner.next();
reverseString r=new reverseString();
System.out.println(r.reversestring(a));



}
}
