Sample midterm solutions |
Listed below are questions similar to those I will put on the midterm. Sample solutions will be posted Thursday.
public static double average(double a, double b)
that returns the average of a and b.
Solution:
public static double average(double a, double b) { double avg = (a + b)/2; return avg; }
public static int minimum(int i, int j)
that returns the smaller of i and j.
Solution:
public static int minimum(int i, int j) { int min; if (i < j) { min = i; } else { min = j; } return min; }
Solution: 4*Math.pow(x,3) +
16*Math.pow(x,2) - 9*x + 56
.
Solution:
int month; do { String s = JOptionPane.showInputDialog(null, "Please enter the number of a month (1 through 12)"); month = Integer.parseInt(s); } while (month < 1 || month > 12);
public class ExampleProgram { public static void main(String[] args) { int index = 0; int total = 0; int upper = 10; while (index <= upper) { total += index; index++; } System.out.println("The total is " + total); } }
Solution: The program prints "The total is 55".
