ANS: block that defines method rollDice’s body. 9, state the scope of each of the following entities: a) the variable randomNumbers. m) The program execution stack is also referred to as the stack. l) In Java, it is possible to have several methods with the same name that each operate on different types or numbers of arguments. k) The of a declaration is the portion of a program that can refer to the entity in the declaration by name. j) If there are more method calls than can be stored on the program execution stack, an error known as a(n) occurs. This data, stored as a portion of the pro- gram execution stack, is known as the or of the method call. i) The program execution stack contains the memory for local variables on each invoca- tion of a method during a program’s execution. h) An object of class produces random numbers.ĪNS: Random. ANS: return or return expression or encountering the closing right brace of a method. g) The three ways to return control from a called method to a caller are, and. f) Stacks are known as data structures-the last item pushed (inserted) on the stack is the first item popped (removed) from the stack. c) The statement in a called method can be used to pass the value of an ex- pression back to the calling method.ĪNS: return d) The keyword indicates that a method does not return a value.ĪNS: void e) Data can be added or removed only from the of a stack. b) A variable known only within the method in which it is declared is called a(n).
