public class StringToASCII {

    public static void main(String args[]) throws ParseException {
        
        // converting character to ASCII value in Java
        char A = 'A';
        int ascii = A;
        System.out.println("ASCII value of 'A' is  : " + ascii);
        
        // you can explicitly cast also
        char a = 'a';
        int value = (int) a;
        System.out.println("ASCII value of 'a' is  : " + value);
        
        
        
        
        // converting String to ASCII value in Java
        try {
            String text = "ABCDEFGHIJKLMNOP";

            // translating text String to 7 bit ASCII encoding
            byte[] bytes = text.getBytes("US-ASCII");
            
            System.out.println("ASCII value of " + text + " is following");
            System.out.println(Arrays.toString(bytes));
            
        } catch (java.io.UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

}

Output
ASCII value of 'A' is  : 65
ASCII value of 'a' is  : 97
ASCII value of ABCDEFGHIJKLMNOP is following
[65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80]

Example 2: how to print ascii value in java

public class AsciiValue {

    public static void main(String[] args) {

        char ch = 'a';
        int ascii = ch;
        // You can also cast char to int
        int castAscii = (int) ch;

        System.out.println("The ASCII value of " + ch + " is: " + ascii);
        System.out.println("The ASCII value of " + ch + " is: " + castAscii);
    }
}

Example 3: how to get ascii value of string letter in java

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