The given code accepts the string and convert this String to char array, cast it to integer(decimal) followed by Integer.toHexString() to convert it to Hex value.

class ConvertAsciiToHex 
{
    public static void main(String[] args) 
    {
        String str="Hello World";
        char[] chars = str.toCharArray();

      StringBuffer hex = new StringBuffer();
      for(int i = 0; i < chars.length; i++){
        hex.append(Integer.toHexString((int)chars[i]));
      }
        System.out.println(hex.toString());
    }
}
