Convert character to ASCII numeric value in java

Question

I have String name = "admin";
then I do String char = name.substring(0,1); //char="a"

I want to convert the char to its ASCII value (97), how can I do this in java?

Answer 1

The character itself gets converted into the ascii code, once we make the character an integer.

You can either cast it,

String name = "admin";

String char = name.substring(0,1); //char="a"

int ascii = (int) char;

OR 

You can directly convert the character to int

String name = "admin";

String char = name.substring(0,1); //char="a"

int ascii = char;
