We have byte and character stream, If you read some examples from internet you can find that byte stream only operates on bytes and nothing more. Once i read that both streams encodes bytes to characters depending on encoding, like if it’s byte stream then utf-8, character stream utf-16. So both of them encodes bytes to characters, if this’s true

Hexadecimal byte array from a Midi event to int
I’m trying to retrieve the tempo of a midi file through the javax.midi library. What I am expected to receive is an array of three ex, because the Set Tempo meta message (which is this case, has just 3 bytes specifying a miliseconds amount. This is how the midi event returns So if you join them you have 0x07A120 which

Answer getHostAddress returns a string representation of an address. So, this method returns something like 192.168.1.100 which can’t be parsed
Java Base64 encoding loss of data
say I have the following snippet, where certificate is a java Certificate object: Is there any chance data will not be equal to newData? basically, is there loss of information to string and then back? Thanks Answer Assuming nothing explodes due to out-of-memory errors or similar general problems, this code should be fine, with one big exception: You are transforming

Java – How to handle special characters when compressing bytes (Huffman encoding)?
I am writing a Huffman Compression/Decompression program. I have started writing my compression method and I am stuck. I am trying to read all bytes in the file and then put all of the bytes into a byte array. After putting all bytes into the byte array I create an int[] array that will store all the frequencies of each
Byte to “Bit”array
A byte is the smallest numeric datatype java offers but yesterday I came in contact with bytestreams for the first time and at the beginning of every package a marker byte is send which gives further instructions on how to handle the package. Every bit of the byte has a specific meaning so I am in need to entangle the
How to Convert Int to Unsigned Byte and Back
I need to convert a number into an unsigned byte. The number is always less than or equal to 255, and so it will fit in one byte. I also need to convert that byte back into that number. How would I do that in Java? I’ve tried several ways and none work. Here’s what I’m trying to do now:
Byte array of unknown length in java
I am constructing an array of bytes in java and I don’t know how long the array will be. I want some tool like Java’s StringBuffer that you can just call .append(byte b) or .append(byte[] buf) and have it buffer all my bytes and return to me a byte[] when I’m done. Is there a class that does for bytes
