Convert character to ASCII numeric value in java
I have String name = "admin";
then I do String charValue = name.substring(0,1); //charValue="a"
I want to convert the charValue to its ASCII value (97), how can I do this in java?
Answer
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.
