Hi @sayiamarora and thank you for your contribution. I have just two little remarks to be addressed. Please, have a look.

Hey @AloisSeckar I have committed the changes please review them

[AloisSeckar]

Thank you, @sayiamarora

The code looks good now, but we recently added new check if the demo collection still runs after the changes and it is failing for your new demo.

The runtime exception is:

Error: Exception in thread "main" java.lang.ClassCastException: class jdk.internal.random.L64X128MixRandom cannot be cast to class java.util.random.RandomGenerator$JumpableGenerator (jdk.internal.random.L64X128MixRandom and java.util.random.RandomGenerator$JumpableGenerator are in module java.base of loader 'bootstrap')
	at org.javademos.java17.jep356.RandomGenerators17.demo(RandomGenerators17.java:33)
	at java.base/java.util.ArrayList.forEach(ArrayList.java:1604)
	at org.javademos.Main.main(Main.java:65)
Error: Process completed with exit code 1.

Can you please check your implementation?

@AloisSeckar have fixed the issue can you please check!!!

[AloisSeckar]

Unfortunately, the pipeline failed again.

I am heading for a sport event now and cannot investigate. Will look in the evening.

I hope I have identified the problems with your PR. Please have a look.

@AloisSeckar used the correct jumpable generator as discussed and correct link I think this time it would work.
