Q38 Kamacoder55 右转字符串

 

简单

 

public class Main {
    public static void main(String[] args) {
        String s = "abcdefg";
        int count=3;
        char[] charArray = s.toCharArray();
        int len=s.length();
        int index=len-count;
        StringBuffer sb=new StringBuffer();
        for(int i=index;i<len;i++){
            sb.append(charArray[i]);
        }
        for(int i=0;i<index;i++){
            sb.append(charArray[i]);
        }
        System.out.println(sb.toString());
    }
}
