Convert character to ASCII numeric value in java

just a different approach

    String s = "admin";
    byte[] bytes = s.getBytes("US-ASCII");

bytes[0] will represent ascii of a.. and thus the other characters in the whole array.

Very simple. Just cast your char as an int.

char character = 'a';    
int ascii = (int) character;

In your case, you need to get the specific Character from the String first and then cast it.

char character = name.charAt(0); // This gives the character 'a'
int ascii = (int) character; // ascii is now 97.

Though cast is not required explicitly, but its improves readability.

int ascii = character; // Even this will do the trick.
