How do you pass a Boolean in Java?

Is there a case statement in PL / SQL?
This omission is odd, since the code for a case condition would probably use 95% of the code for the case expression. All the more weird since PL/SQL does have the boolean type, and the case expression there works seamlessly for Booleans.
Is it possible to make use of a case statement in Oracle?
But it is possible to make use of one. The problem in the original query is that Oracle is more strict than other databases (like MySQL) in that Oracle doesn’t implicitly convert a boolean expression to a value, or convert a value into boolean. I suspect that Oracle is choking in a couple of places.
How to set a variable based on a parameter?
I’m trying to set an SQL variable based on the numerical value of a different SQL parameter passed into a stored procedure, but having trouble with the exact syntax of the Case statement
