Answer 2.7 and 2.8 of the In Theory questions. For question 2.8, only turn in what value is returned by foo and what exception is thrown by bar, not your program. o Note: You will need to change the foo method to "int" instead of "void" IN THEORY 2.7 If x and y have the values of 5 and 7, respectively, what is output by the following? System.out.println( x + ' ' + y ); System.out.println( x +""+y); 2.8 The finally block introduces complications in the Java language specification. Write a program to determine what value is returned by foo and what exception is thrown by bar in Figure 2.21. public static void foo() figure 2.21 Complications caused by the finally block. return 0; finally return 1; public static void bar() try throw new NullPointerException(); finally throw new ArithmeticException()
