All, I created a sample key generator which generates UUIDs (with lots of hex for the output like this): import java.util.UUID; public class KeyGenerator { public UUID getKeysFromInputSeeds(long startTimeStamp, Number sequenceId) throws Exception { String concatenatedSeeds = Long.toString(startTimeStamp) + sequenceId.toString(); byte[] inputSeeds = concatenatedSeeds.getBytes(); return getKeyFromBytes(inputSeeds); } private UUID getKeyFromBytes(byte[] seed) { return UUID.nameUUIDFromBytes(seed); } } The main app: public class ... |
I have an idea. I want to store color information in a short instead of an int. Currently color information is stored in an int like so: 0x00RRGGBB I want to use this format: 0x0RGB Is there a formula or bit shift I can use to do the conversion back and forth? I realize I will have less colors to work ... |
This is probably way to easy, but does anyone have any suggestions as to how I can easily convert an integer input into hexadecimal. This assignment calls for the user to be able to enter a number from 0-100,000, and that number be converted to hex. There has to be an easier way of converting than a huge branching if...else if..etc. ... |
Why are you converting a byte[] into a StringBuffer/String? Seems odd to me. Anyway, one way to reverse a process is to reverse each step. For example, how can you convert "A0" back to a byte? Take a look at the methods of Integer. In the final step, to convert a byte[] to an Image, take a look at class javax.imageio.ImageIO, ... |
Hello everyone. This is the second time I've came here with a specific question. Everyone was great last time - I learned so much in the process. This time, my question is quite simple. Basically, I am inputting an integer. The integer needs to be transformed into a "hexcode." In this example, 525 is input. It needs to be turned into ... |

Hi! I have a String which represents a hexadecimal number (e.g. "5FA2"). Ideally, I would like to convert this String into an int (e.g. 0x5FA2), is there a quick way to do this ? I can't use the method "Integer.parseInt()" since my String represents an hexadecimal and not a decimal. Thanks in advance! |

My instructions are: Modify your program to ... |
Sorry must be clearer. I'm pretty sure that I am not returning the name variable from the for loop correctly so that the callbackhandler can pick up the hexadecimal string (which is what I am attempting to get for the rest of my code). Do I need to rename the new hexed string to something like hexname? The original cookie code ... |

cotton thanks for your reply, but I dont want only to print, I mean when I checked that value should be like : 0xc0a80000 , but not my intention is to print that. If I do want to print like that , I can write like : System.out.println("0xc0a80000"); I think you understood my question. |

Hi Everyone, Here is my challenge. I am given a very large number in a String. I am also given the maximum number of bits this number can occupy. However, this number probably will not fit into a standard Data Type such as long, int, or double. I also need to send this number to a piece of hardware in a ... |

Take your Hex (base16) and use the Base64Encoder. It does not matter what base your source is, as that is independent of the operation you are performing. The encoder will change the given data based on it's formula to produce a result. The decoder will take that result and produce the original content (weather it was base64, base10, base16). Short: Use ... |
