Hi, I got an interesting Q for you ... int y = 4; System.out.println("Value is "+((y >4 )? 99.99:9)); this will print 9.0. whereas System.out.println("Value is "+((y >4 )? 99:9)); will print 9. Why is this?

Sean, That is an intresting observation....what happens is when even one of the variables is double the other gets converted to double automatically.....in the first case 9 is getting promoted to double...coz the other condition variable is of type double...for eg: int y = 3; System.out.println("Value is "+((y <4 )? 99:9.5)); The result will be 99.0....... Correct me someone if I am wrong.... Thanks, Harpal

That looks right to me. I guess because ? returns a value it has to return the same type either way and it has to choose the wider type.
