把字符串abcdef旋转2位得到字符串cdefab

public class RightShift {
 public static void main(String args[]) {
  char[] c = { 'a', 'b', 'c', 'd', 'e' };
  for (int i = 0; i < c.length; i++) {
    System.out.print(c[i]);
   }  for (int i = 0; i < 2; i++) {
    char temp = c[0];
    for (int j = 0; j < c.length - 1; j++) {
     c[j] = c[j + 1];
    }
    c[c.length - 1] = temp;
   }
   System.out.println();
   for (int i = 0; i < c.length; i++) {
    System.out.print(c[i]);
   }
  }}
