user28219: Java is sooooooo much easier than C++. Wondering why in 2008 people decided to go with C++ instead. Was it because Satoshi only knew C++?
And to compliment this question, is there a noticeable cryptocurrency implemented in java from scratch?

user11253: There is at least one bitcoin implementation in Java. Not everybody "decided to go with C++", and the choice of implementation language has no bearing on the underlying network protocol. Anybody is free to implement the bitcoin algorithm in any programming language they choose.
Speculating on which programming languages Satoshi did or did not know is pointless, because it is generally agreed that he is a fictional persona.
