StringBuffer实现字符串翻转

public class StringOutput {

public static void main(String[] args) {
String str ="abcdef";

StringOutput sOutput = new StringOutput();
System.out.println(sOutput.StrReverse(str));

}

public String StrReverse(String s){
StringBuffer sb = new StringBuffer(s.length());
for (int i = s.length()-1; i>=0 ; i--) {
sb.append(s.charAt(i));
}
return sb.toString();
}
}
