bytearray

问题 How Can I get the date time in unix time as byte array which should fill 4 bytes space in Java? Something like that: byte[] productionDate = new byte[] { (byte) 0xC8, (byte) 0x34, (byte) 0x94, 0x54 }; 回答1: First: Unix time is a number of seconds since 01-01-1970 00:00:00 UTC. Java's System.currentTimeMillis() returns milliseconds since 01-01-1970 00:00:00 UTC. So you will have to divide by 1000 to get Unix time: int unixTime = (int)(System.currentTimeMillis() / 1000); Then you'll have to get

问题 I am trying to write an Integer from C# and read it from Java. An integer is 4 bytes in both languages. However when I write it from C#, integer 1 is written in the following bytes 1000. Meaning the first byte is 1 and the rest is 0. But in Java the same thing is written as 0001. Meaing the first 3 bytes are 0 and the last is 1. Is there a simple way of reading and writing among these languages instead of manually reversing every 4 byte? The code for Java ByteBuffer buffer = ByteBuffer

问题 I have a byte[] that I've read from a file, and I want to get an int from two bytes in it. Here's an example: byte[] bytes = new byte[] {(byte)0x00, (byte)0x2F, (byte)0x01, (byte)0x10, (byte)0x6F}; int value = bytes.getInt(2,4); //This method doesn't exist This should make value equal to 0x0110 , or 272 in decimal. But obviously, byte[].getInt() doesn't exist. How can I accomplish this task? The above array is just an example. Actual values are unknown to me. 回答1: You should just opt for the

问题 I'm trying to play a wav sound that stored in byte array called bytes. I know that I should convert the byte array to wav file and save it in my local drive then called the saved file but I was not able to convert the byte array to wav file. please help me to give sample code to convert byte arrary of wav sound to wav file. here is my code: protected void Button1_Click(object sender, EventArgs e) { byte[] bytes = GetbyteArray(); //missing code to convert the byte array to wav file ...........
