help with basic java code

[elizabeth]

Can I this function better?

//Calculate Csum A = A XOR B
byte CountCsum(String m) {
byte[] inData = m.getBytes();
byte csum=0;
// Don't Count the first byte
for(byte n=1;n<m.length();n++)
csum ^= inData[n];

return csum;
}

In C you normally sending a pointer to an array into the function but here I must convert the string to byte array
an that takes time and memory.

Are java sending a reference to the string or the entire string to the function??

Java is pass-by-reference, so the argument to your method is a copy of the reference to the original String.
