java反转字符串

public class test{
public static void main(String[] args) {
  Scanner input = new Scanner(System.in);
  System.out.print("请输入：");
  String s1 = input.nextLine();//得到输入的字符串
  System.out.print("翻转后：");
  for(int i=s1.length()-1;i>=0;i--){
   System.out.print(s1.charAt(i));
  }
 
}
}

 

另:写一个方法，实现字符串的反转

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