If you are using the InputStream OutputSream, then the the read is
reading the value of each character as an integer.
Therefore, to change the lower case letters all you need to do is the
following in your read methods:
int b = in.read();
if(b >= 97 && b <= 122)
b -= 32;
if you want to verify to System.out.println
that it changed it properly, you can do something like this:
String myString = "";
int b = in.read();
if(b >= 97 && b <= 122){
b -= 32;
myString += b;
}
System.out.println(myString);
