Java integer to byte array
arrays, byte, integer, java
Solution
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
Problem
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?
