Required fields*

Print all ASCII alphanumeric characters without using them

Challenge

Print the following characters:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890

The catch is that you may not use any one of them in your code.

You may print them in arbitrary order, with or without a leading or trailing newline, but you may not print any other characters.

Rules

You may not use any characters from the set mentioned above
You may use any other characters
No cheating
Standard loopholes banned
This is code-golf, shortest answer wins.

Clarifications

If your language uses a different charset, you may not use codepoints in that charset that correspond to alphanumeric characters.
Returning a string from a function is considered a valid form of output.
You may return a char array.

Yes, Java, you read that well!

This prints the ranges, but reversed, since the order has no importance.

I played on the absence of "no input" rule to implicitly define a `char` which is required to make the whole thing work. If that's cheating, please say so.

## Ungolfed & testing

    public class PCG105781 {
      interface X { String apply(char x); }

      public static void main(String[] args) {
        X x = $
            -> "" // Force the result as a String.
            // The line below appends "zyxwvutsrqponmlkjihgfedcba"
            // '=' + '=' is 122 as int. $=122 casts 122 as a char, 'z'
            + ($ = '=' + '=') + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$
            // The line below appends "ZYXWVUTSRQPONMLKJIHGFEDCBA"
            // '-' + '-' is 90 as int. $=90 casts 90 as a char, 'Z'
            + ($ = '-' + '-') + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$
            // The line below appends "9876543210"
            // '_' - '&' is 57 as int. $=57 casts 57 as a char, '9'
            + ($ = '_' - '&') + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$ + --$
          ;

        System.out.println(x.apply('_'));
      }
    }

If this is an answer to a challenge…

…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one. Explanations of your answer make it more interesting to read and are very much encouraged.
…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.

More generally…

…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

\$\begingroup\$ That's because JavaScript doesn't have char, otherwise it'd be a piece of cake. And to be fair, my answer is shorter than your initial answer. Take a look at my explanation for all the overhead I have to go through. \$\endgroup\$

\$\begingroup\$ @PatrickRoberts To be fair, we should compare initial edit to initial edit or last edit to last edit, not initial edit to last... ;) I carefully read what was done for JavaScript, especially because I didn't understand how I could get a shorter answer than all of the JS ones. \$\endgroup\$
