rword | cryptographically secure random generator | Runtime Evironment library

base.indexOf(highlight) ==> indexOf() returns the first occurrence of highlight in base , thats why the underline span jumps to first "the" instead of the next occurrence. You can use indexOf(String str, int fromIndex). The following code tracks the "fromIndex" in this variable "nextStartIndex", and also underlining resets to first word after completing the sentence.

You're calling the methods on the class penGame, not on a instance of penGame. This causes your missing argument error because the method needs an instance of the class (the self parameter) but don't get one. Instead use your variable (from the second solution):

Here is an easier option with gsubfn

The issue here is: Where are the database files? By default, HSQLDB creates an empty database when none exists at the given URL. In order to ensure your database URL points to the correct location, append ;ifexists=true at the end of both jdbcUrl properties. See http://hsqldb.org/doc/2.0/guide/dbproperties-chapt.html#dpc_connection_props

Second, the paths in the jdbcUrl's that you specify are file:, which means a directory structure, but the paths look like pointing to a jar (res:) resource. If the database is in a jar, use the correct type of URL.

If the database files are not in a jar, but are stored in a read-only location in the given directory structure, you may still be able to connect with res:.

As suggested in comments, the current range of rWord is 1,2,3,4,5 which must be fixed to 0,1,2,3,4. Thus I removed +1 from it's initialization equation in the following answer. In addition, ranLN can be duplicate thus you got repeated letters.

Then, a possible way is recursively shuffling all characters of randWord and output them after the while loop finished as follows. The same algorithm is shown here as an example:

I misspelled "lambda", closing this question.

I assume this is what you are looking for, but before you take and use this code, consider these few things: the way your code is written is not maximizing the use of Java being object oriented. This code would be far more legible and better in general should it have more than one class. The Main class should only be used to initialize another class or group of classes. Okay so now for the code. This should do the trick:

Try the following to do the shift. You will need to loop. Spelling checks are performed in a loop.

If you build a prompt (or provide SSML) that first plays an audio file (i.e. uses the audio SSML tag), and then has some text to speak after that, the SpeechSynthesiser does not honor your Cancel request once it has started speaking the text (although it will happily Cancel if it is still playing the audio file). if you put the text first (before the audio file), everything works as expected (you can Cancel the speaking of the text or the playback of the following audio file). building a prompt with just text to speak can be Cancelled with no problems.

work-around:

Instead of building a prompt with both an audio file followed by the text to speak, you build two prompts, the first with just the audio file, and the second with just the text to speak.

You then call SpeakAsync on both prompts (in the correct order).

Now when you call SpeakAsyncCancelAll, it will Cancel whatever prompt is playing (whether it is the audio file prompt or the speaking prompt). The SpeakCompleted handler is invoked as expected for each prompt that was cancelled.

You can also use SpeakAsyncCancel(prompt), although you would need to call it for each prompt that you created.

NB not sure why it doesn't actually work properly when you build a prompt that contains first an audio file, then text to speak, though.
