For example, 490 is a decimal literal, whereas 0x50A or 0X50A is a hexadecimal literal, equivalent to the decimal value 490. Please note that the prefixes 0x and 0X define the same thing.

        double height = 490; 
        double width = 1290; 
 
        double heightInHex = 0x1EA; // equivalent to decimal 490 
        double widthInHex = 0x50A; // equivalent to decimal 1290

      } 
    }
