Can someone please suggest a way to effectively copy the bytes from one array to another.
In my program a user will call the method setDate(byte buf) which will set data continuously ie
inside the method there is an array say buf2.
for example if the method is called with 2 bytes as argument. then it is copied to buf2.
if again the method is called with 4 bytes as arguments. then data is stored in buf2 ... buf2 using for loop.
If the argument is of 10000 bytes then the performance is hit. Can you please suggest a faster way or algorithm to copy bytes from one array to another
