cannot convert from long to byte

[Nikos Stavros]

for some reason I get this error in this code, how can I fix it?

   byte[]b = new byte[4];

b[0] =  (aLongNumber & 0xFF000000L) >> 24;

Are you familiar with casting?

[Nikos Stavros]

yes, I tried this and it worked, thanks

  buf[0] = (byte)(anUnsignedInt & 0xFF000000L >> 24);
buf[1] = (byte)(anUnsignedInt & 0x00FF0000L >> 16);
buf[2] = (byte)(anUnsignedInt & 0x0000FF00L >> 8);
buf[3] = (byte)(anUnsignedInt & 0x000000FFL);  

[Nikos Stavros]

however I get strange results

 Convert_int_into_4_bytes(312243);
 

 
public void Convert_int_into_4_bytes(long anUnsignedInt){

 
byte[]buf = new byte[4];

buf[0] = (byte)(anUnsignedInt & 0xFF000000L >> 24);
buf[1] = (byte)(anUnsignedInt & 0x00FF0000L >> 16);
buf[2] = (byte)(anUnsignedInt & 0x0000FF00L >> 8);
buf[3] = (byte)(anUnsignedInt & 0x000000FFL);
 




System.out.print(buf[0] + " " + buf[1] + " " + buf[2] + " " + buf[3]);   

It prints out "-77 -77 -77 -77" I can figure out why I get the same numbers

Hint: The >> operator has preference above the & operator.
