inttobytearray 方法没有参数,它只需要一个整数作为输入。这个整数就是需要转换为字节数组的数据。 3.inttobytearray 方法的返回值 inttobytearray 方法的返回值是一个字节数组(byte[]),它包含了输入整数所转换的字节。如果输入的整数为 0,那么返回的字节数组将为空。 4.inttobytearray 方法的使用示例 下面是一...

下面是使用ByteBuffer类实现int数组转byte数组的代码示例: importjava.nio.ByteBuffer;publicbyte[]intArrayToByteArray(int[]intArray){ByteBufferbuffer=ByteBuffer.allocate(intArray.length*4);for(inti=0;i<intArray.length;i++){buffer.putInt(intArray[i]);}buffer.flip();byte[]byteArray=newbyte[buffer.re...

I have found a solution to this problem on : http://stackoverflow.com/questions/9887930/c-copy-32-bit-integer-into-byte-array I make a function like : vector<char> GetArrayofByteFromInt(int number){ vector<char> chars; char* a_begin = reinterpret_cast<char*>(&number); ...
byte[] bytes = new byte[buffer.remaining()];buffer.get(bytes);// process bytes...buffer.clear();} 最后，可以使用InputStream.toByteArray()方法，该方法会一次性读取所有数据并返回一个byte数组：byte[] bytes = new byte[in.available()];in.read(bytes);以上就是Java InputStream流转换...
