What are all the similarities and diferences between them, It looks like Java Parallel Stream has some of the element available in RXJava, is that right?

It is true that Java 8 supports both parallel and sequential stream.
The performance of both streams degrades fast when the number of values increases. However, the parallel stream performs worse than the sequential stream in all cases.
Parallel Stream takes benefits of all available CPU cores and processes the tasks in parallel. If the number of tasks exceeds the number of cores, then remaining tasks wait for currently running task to complete.
Until we realized just how much performance can suffer from overusing them. To be clear, streams introduced in Java 8 were slow and the comparison from the title started to arise in many forms. Still the advantages were clear and once Java 11 came, streams were greatly optimized.
Rx is an API for creating and processing observable sequences. The Streams API is for processing iterable sequences. Rx sequences are push-based; you are notified when an element is available. A Stream is pull-based; it "asks" for items to process. They may appear similar because they both support similar operators/transforms, but the mechanics are essentially opposites of each other.
