I get lost on the java I/O FilterInputStream
1) what is the main step in FilterInputStream??
2) I have
public ToUpClassInputStream(InputStream in) {
super(in);
}
public int read() throws IOException {
int b = in.read();
// printing, ASCII characters
if(Character.isLowerCase(b))
b=Character.toUpperCase(b);
return b;
}
not ideal how to write the
public int read(byte[] data, int off, int len) throws IOException {
???????
}
