Answer 1

Convert a letter in hex code and hex code in letter.

        String letter = "a";
    String code;
    int decimal;

    code = Integer.toHexString(letter.charAt(0));
    decimal = Integer.parseInt(code, 16);

    System.out.println("Hex code to " + letter + " = " + code);
    System.out.println("Char to " + code + " = " + (char) decimal);
