11.Analyze the following code: public class Test { public static void main(String[] args) { int[] x = new int[5]; int i; for (i = 0; i < x.length; i++) x[i] = i; System.out.println(x[i]); } }

12.You may or may not recall that the standard Java computing environment contains a Math class that includes a method called random() which returns a double as described below: public class Math { // The following method returns a double value with a // positive sign, greater than or equal to zero, // but less then 1.0, chosen "randomly" with approximately // uniform distribution from that range. public static double random() { ... } ... } Which one of the following expressions has a value that is equally likely to have any integer value in the range 3..8?

13.A proposed graduated state income tax applies the following rate schedule to net income after deductions: 0 --- if the net income is negative #2% --- on incomes less than $10,000 $200, plus 4% of excess over $10,000 --- for incomes between $10,000 and $20,000 (inclusive) $600, plus 6% of excess over $20,000 --- for incomes between $20,000 and $30,000 (inclusive) $1,200, plus 8% of excess over $30,000 --- for incomes greater than $30,000 You have been given a program that is supposed to calculate the tax on a given income in dollars. Which one of the following is the best set of test data on which to try out this program?

14.Suppose the following Java statements: char ch = ' '; try {do {ch = (char) System.in.read(); } while ( ch != 'G'); } catch(Exception i) { System.out.println(ch); } are executed and applied to the following input which is typed on the keyboard: g MnGyZ The final value of the variable ch will be:
