Java: Can Function have a parameter for an array of a specific length? [duplicate]

Question

I am making a subroutine that will convert a 8-bit binary number into a int value. I want it to take as a parameter a int array with a length of 8 (to represent the binary number) and reject arrays of any other length. Is the possible?

You can check for the length of the given array at the start of the method and throw an exception / return null. — influjensbahr

It is not possible to ensure the length of an array at compile time. You have to use

if(my_array.length != 8){
    throw new Exception("Array must have a length of 8.");
}
