Welcome to JavaRanch!
"smash" references an instance of NewVirus, and NewVirus has a method called setNewSeconds...
Basically, this method checks to see if the int parameter (the value in the parentheses) is greater than 59 and less than 101. If it is, then the method sets "newSeconds" to this value and returns true. Otherwise, it returns false.
So the expression...
(smash.setNewSeconds(30) == true)
...passes the value 30 to this method, then uses the comparison operator == to
test whether smash.setNewSeconds(30) is true -- that is, whether "newSeconds" was set to 30 or not.
