I got an integer: 1695609641
when I use method:
String hex = Integer.toHexString(1695609641);
system.out.println(hex);
gives:
6510f329
but I want a byte array:
byte[] bytearray = new byte[] { (byte) 0x65, (byte)0x10, (byte)0xf3, (byte)0x29};
How can I make this?
using Java NIO's ByteBuffer is very simple:
byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();
for (byte b : bytes) {
System.out.format("0x%x ", b);
}
output:
0x65 0x10 0xf3 0x29
