Question

Summary

In this lab the completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a for loop instead of a counter-controlled while loop.

Instructions

1. Write a for loop that uses the loop control variable to take on the values 0 through 10.
2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10.
3. Execute the program. Is the output the same?

4. // NewMultiply.java - This program prints the numbers 0 through 10 along
   // with these values multiplied by 2 and by 10.
   // Input: None.
   // Output: Prints the numbers 0 through 10 along with their values multiplied by 2 and by 10.

   
   public class NewMultiply
   {
   public static void main(String args[])
   {
     
   String head1 = "Number: ";
   String head2 = "Multiplied by 2: ";
   String head3 = "Multiplied by 10: ";   
   int numberCounter; // Numbers 0 through 10.
   int byTen; // Stores the number multiplied by 10.
   int byTwo; // Stores the number multiplied by 2.
   final int NUM_LOOPS = 10; // Constant used to control loop.

   // This is the work done in the housekeeping() method
   System.out.println("0 through 10 multiplied by 2 and by 10" + "\n");

   // This is the work done in the detailLoop() method
   // Write for loop
   
   // This is the work done in the endOfJob() method
   System.exit(0);
   } // End of main() method.

   } // End of NewMultiply class.

Answer 1

public class NewMultiply
{
  public static void main(String args[])
  {

    String head1 = "Number: ";
    String head2 = "Multiplied by 2: ";
    String head3 = "Multiplied by 10: ";
    int numberCounter; // Numbers 0 through 10.
    int byTen; // Stores the number multiplied by 10.
    int byTwo; // Stores the number multiplied by 2.
    final int NUM_LOOPS = 10; // Constant used to control loop.

// This is the work done in the housekeeping() method
    System.out.println("0 through 10 multiplied by 2 and by 10" + "\n");

// This is the work done in the detailLoop() method
    System.out.println(head1+"\t"+head2+"\t"+head3);
    for(numberCounter = 0;numberCounter<=NUM_LOOPS;numberCounter++){
      byTwo = numberCounter * 2;
      byTen = numberCounter * 10;
      System.out.println(numberCounter+"\t\t\t"+byTwo+"\t\t\t\t\t"+byTen);
    }
// Write for loop

// This is the work done in the endOfJob() method
    System.exit(0);
  } // End of main() method.

} // End of NewMultiply class.
