If you want to print is as an array

System.out.println(Arrays.toString(s));

if you want to print as a String

System.out.println(new String(s));

btw you can write

char[] s = new char['Z' - 'A' + 1];
for(char ch = 'A'; ch <= 'Z'; ch++)
   s[ch - 'A'] = ch;

  • From the Javadoc `Returns a string representation of the contents of the specified array. The string representation consists of a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (a comma followed by a space). Elements are converted to strings as by String.valueOf(char). Returns "null" if a is null.` – Peter Lawrey Jan 04 '13 at 12:21

You can just use Arrays.toString(s) and print the resulting String.
