Java in writting a byte

Question

If we write integer or double through java in a file then the bit pattern for eanch is reverse than any other language (like C/ delphi .e:g delphi writes an integer as A@~! but java writes as !~@A).
How can we convert java pattern to other pattern for integer and float/double?

Answer 1

Then you must split the integers to bytes in the order you want.
You can do it like this
public byte[] toBytes(int i) {
  byte[] b = new byte[4];
  byte b[0] = (i & 0xff000000) >>> 24;
  byte b[1] = (i & 0x00ff0000) >>> 16;
  byte b[2] = (i & 0x0000ff00) >>> 8;
  byte b[3] = i & 0x000000ff;
public int toInt(byte[] b) {
  int i = (b[0]<<24)+(b[1]<<16)+(b[2]<<8)+b[3];
}Maybe this example is in the reverse order that you want, but it's easy to make it the other way around.
With these methods you can read and write bytes from a stream and convert them to and from integers.
Regarding float, you can convert it to an int first, and then use
float f = Float.intBitsToFloat(toInt(b));
where b again is a bytearray of 4 bytes using the described method.
Something similar can be done with long and double.
