File size:

| 1 | This directory contains a small example of a scanner for binary files.

| 3 | The example tries to detect if an input file is a java class file by
|
|---|
| 4 | checking if the first 4 bytes contain the magic number 0xCAFEBABE.
|
|---|
| 5 | It uses a custom Reader class that copies bytes to characters one to
|
|---|
| 6 | one. The characters the scanner gets to read are the bytes from the
|
|---|
| 7 | input stream without any conversion. Many thanks to Stephen Ostermiller

| 8 | for providing the custom Reader class, the original version of that
|

| 9 | class is available from http://www.smo.f2s.com/utils/
