Sample final questions

Listed below are questions similar to those I will put on the midterm. Sample solutions will be posted Thursday.

• Write a method with the header:

  public static int find(int[] A, int key)

  that searches for the value of key in the array A and returns its index if it's there but -1 if it's not.
  

• Write a method with the header:

  public static int minimum(int i, int j, int k)

  that returns the smallest of i, j, and k.
  

• Write a loop that prompts the user for a year, which is an integer between 1995 and 2003 (inclusive).  
  
• Write an applet that displays a red square that is 50 pixels by 50 pixels and in the upper left corner of the applet window.
  
• Write a method that returns the second largest element in an array.
  
• What are the three parts of a class definition?
  
• What is printed by the following program?

  public class ExampleProgram {
      public static void fillArray(int[] A) {
          for (int i = 0; i < A.length; i++) {
              A[i] = i*i;
          }
      }
    
      public static int processArray(int[] A) {
          int s = 0;
          for (int i = 0; i < A.length; i++) {
              s += A[i];
          }
          return s;
      }
   
      public static void main(String[] args) {
          int[] A = new int[10];
          fillArray(A);
          System.out.println(processArray(A));
          System.exit(0);
      }
  }
