问如何旋转字符串，一次旋转一个字符？

import java.util.Scanner;

public class String_pattern_01 {



public static void main(String[] args) {

        Scanner sc= new Scanner(System.in);
        System.out.println("Enter the character in continuation to get the pattern");
        String s=sc.next();
        int d=s.length();
        String s2[]=s.split("");
        for(int i=0;i<=s.length();i++)
        {    
            String x= s.substring(i, d);

            if(i>=1&i<d)
            {
                for(i=1;i<d;i++)
                {String y=x+x.substring(0,i-1);
                System.out.println(y);}
            }
            else
            {

                System.out.println(x);
            }

        }

    }
