Incompatible type for method

Question

this is for school so you don't have to answer if you choose not to.
i have to have method signature that reads
public void BFEncrypt(String source, String target, byte code)throws IOException, FileNotFoundException{
but when i call the method
bfp.BFEncrypt("C:/WINDOWS/Desktop/ASSIGN3/test.txt","result.txt",12);
i'm told i have to convert an int to byte. it is defaulting the 12 at the end of the call to an int. i got the class, which is to read a file, encode it using the simple code passed in, and then re-write to work fine when making the signature int code. I was told that it had to be byte though and i can't get it to work.
thanks in advance

Answer 1

Well, then overload the method..
public void BFEncrypt(String source, String target, int code)throws IOException, FileNotFoundException {
   //whatever goes here
public void BFEncrypt(String source, String target, byte code)throws IOException, FileNotFoundException {
   BFEncrypt(source, target, (int) code);
}You could even test for values >127 <-128 and throw an exception. And you can use the same technique for short or long. (I did not try to compile this so no guarantees.)
