I don't think this code is syntactically correct.

FinancialInstrument fi = //get it somehow
switch(fi){
   case fi instanceof Bond b -> valueBond(b);
   case fi instanceof Stock s -> valueStock(s);
   default -> throw new RuntimeException("Can't deal with this financial instrument!");
}

You are right. It should be :

Code: Select all

switch(fi){
case Bond  b ->  valueBond(b); 
case Stock s -> valueStock(s);
default -> throw new RuntimeException("Can't deal with this financial instrument!");
}

Please tell us your name so that you can be credited in the book.

thank you for your feedback!
