Unsigned modulo in Java

I’m porting some c code which is doing a modulo on an uint32_t. An uint32_t fits in a Java int bit-wise, but I cannot figure out how to perform a modulo operation on it without converting to a long. This is the code I have right now:

int i = 0xffffffff;
long asUnsigned = Integer.toUnsignedLong(i);
int mod = (int) (asUnsigned % 42L);

Can I perform this modulo calculation without converting to long?

Answer

Use Integer.remainderUnsigned(int dividend, int divisor) (javadoc):

Returns the unsigned remainder from dividing the first argument by the second where each argument and the result is interpreted as an unsigned value.
