Get ASCII from char from string

Question

I have a loop with i incrementing through a string, and I want to print that character, but its ASCII code.

myString = "90210";
for (int i = 0; i < myString.length(); i++) {
    System.out.println(myString.charAt(i));
}

To output:

Obviously charAt() doesn't do this, but I need another method to append to it to get my desired result.

Just cast to an int so that you get the numerical value of the char, which consequently uses the overloaded println(int) method

System.out.println((int)myString.charAt(i));

System.out.println(myString.charAt(i) - '\0');
System.out.println(myString.charAt(i) - 0);

That's a pretty curious way to cast. – Radiodef Mar 09 '14 at 00:24
For curious people, this works because a `char (op) char`, where `op` is any of the `+, -, *, /, %` operators, results in an `int` value. This is actually true for all numeric types smaller or equal to an `int`. – Sotirios Delimanolis Mar 09 '14 at 00:27
