Can't resolve the last challenge in this chapter.

What I did

// assetManager, assetName, and fileToWrite have been initialized elsewhere
try {
InputStream in = assetManager.open(assetName);
FileOutputStream out = new FileOutputStream(fileToWrite);
copyFile(in, out);
} catch(Exception e) {
  printStackTrace(e.getMessage());
}

and what error I received.

JavaTester.java:68: error: cannot find symbol
  printStackTrace(e.getMessage());
  ^
  symbol:   method printStackTrace(String)
  location: class JavaTester
1 error

Can somebody show my mistake? Thanks.

printStackTrace is a method of Exception inherited from Throwable. You'll need to call it with the Exception object:

e.printStackTrace();
