1?Suppose your method does not return any value, which of the following keywords can be used as a return type? A. void B. int C. double D. public E. None of the above A 2? The signature of a method consists of ____________. A. method name B. method name and parameter list C. return type, method name, and parameter list D. parameter list B 3? All Java applications must have a method __________. A. public static Main(String[] args) B. public static Main(String args[]) C. public static void main(String[] args) D. public void main(String[] args) E. public static main(String[] args) C 4? Arguments to methods always appear within __________. A. brackets B. parentheses C. curly braces D. quotation marks B 5? Does the return statement in the following method cause compile errors?public static void main(String[] args) {??int max = 0;??if (max != 0)????System.out.println(max);??else????return;} A. Yes B. No B Explanation: It is rare, but sometimes useful to have a return statement for circumventing the normal flow of control in a void method. 6? Does the method call in the following method cause compile errors?public static void main(String[] args) {??Math.pow(2, 4);} A. Yes B. No B Explanation: A method with a nonvoid return value type can also be invoked as a statement in Java. In this case, the caller simply ignores the return value. This is rare, but permissible if the caller is not interested in the return value. 7? Each time a method is invoked, the system stores parameters and local variables in an area of memory, known as _______, which stores elements in last-in first-out fashion. A. a heap B. storage area C. a stack D. an array C 8? Which of the following should be declared as a void method? A. Write a method that prints integers from 1 to 100. B. Write a method that returns a random integer from 1 to 100. C. Write a method that checks whether current second is an integer from 1 to 100. D. Write a method that converts an uppercase letter to lowercase. A
