Problem med generic parameter værdi?

Java kode 

 import java.util.*;
 
 class apples 
 {
     public static void main(String args[])
     {
         Integer[] iray = {1, 2, 3, 4};
         Character[] cray = {'a', 'b', 'c', 'd'};
         
         printMe(iray);
         printMe(cray);
     }
     
     public static <T> void printMe(T[] x)
     {
         for(T a : x)
         {
             System.out.printf("%s ", x);
         }
         System.out.println();
     }
 }
