Get ASCII from char from string [duplicate]

Get ASCII value at input word (6 answers)

Closed 9 years ago.

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:

57
48
50
49
48

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

Answer 1

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));

Answer 2

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