You can use Character.isUppercase() method.

public class MainClass {
  public static void main(String args[]) {
     System.out.println(Character.isUpperCase('C'));
  }
}

See Javadoc

   String s="Ëfdk,Ä";
   char[] a = s.toCharArray();
   for (int i=0;i<a.length;i++)
   {
       if ( a[i] != null && Character.isUpperCase(a[i]))
           System.out.println(a[i]);
   }
