Converting Characters to ASCII Numeric Values in Java

Question:

Given a string, how can you extract a specific character and convert it to its ASCII numeric value in Java?

Answer:

To convert a character to its ASCII numeric value in Java, use the following steps:

Step 1: Extract the Character

Extract the character you want to convert from the string using the charAt method.

<code class="java">String name = "admin";
char character = name.charAt(0); // character is now 'a'</code>

Step 2: Convert the Character to ASCII

Cast the extracted character as an integer to obtain its ASCII numeric value.

<code class="java">int ascii = (int) character;</code>

Step 3: (Optional)

Casting the character as an integer is not strictly required, but it improves code readability. The following code will also work:

<code class="java">int ascii = character;</code>

In your specific case, where charValue is a string containing a single character, you can use:

<code class="java">char character = charValue.charAt(0);
int ascii = (int) character;</code>
