Ans:

A finally block can appear after the try and catch blocks, and it can contain code that is run regardless of what happens within the try and/or catch blocks.

For example:

try {
  trace("try");
}
catch (errObject:Error) {
  trace("catch");
}
finally {
  trace("finally");
}
//output: try, finally

Since no error is thrown, the catch block doesn't run. However, the finally block does run.

Similarly, the finally block will run even when an error is thrown:

try {
  throw new Error();
  trace("try");
}
catch (errObject:Error) {
  trace("catch");
}
finally {
  trace("finally");
}
//output: catch, finally
