在java中将字符转换为ASCII数值
问题描述：
我有 String name =admin;
然后我做 String char = name.substring（0， 1）; // char =a
我想将 char 转换为ASCII值（97），如何在java中执行此操作？
I want to convert the char to its ASCII value (97), how can I do this in java?
答
非常简单。只需将 char 转换为 int 。
Very simple. Just cast your char as an int.
char character = 'a';
int ascii = (int) character;
在您的情况下，您需要首先从字符串中获取特定字符然后再进行转换。
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.
虽然不需要强制转换，但是它提高了可读性。
Though cast is not required explicitly, but its improves readability.
int ascii = character; // Even this will do the trick.
