(a)

Program Plan Intro

Given Program:

public class Test {

  //Main Method

  public static void main(String[] args) {

    //Initialize number

  int number = 0;

    int[] numbers = new int[1];

    m(number, numbers);

    //Display the number

    System.out.println("number is " + number

      + " and numbers[0] is " + numbers[0]);

  }

  public static void m(int x, int[] y) {

    x = 3;

    y[0] = 3;

  }

}

(b)

Program Plan Intro

Given Program:

import java.util.Scanner;

public class Test{

  //Main Method

  public static void main(String[] args) {

//Initialize the numbers

    int[] list = {1, 2, 3, 4, 5};

    reverse(list);

    //Display the list

    for (int i = 0; i < list.length; i++)

      System.out.print(list[i] + " ");

  }

  //Method to find the reverse

  public static void reverse(int[] list) {

    int[] newList = new int[list.length];

    for (int i = 0; i < list.length; i++)

      newList[i] = list[list.length - 1 - i];

    list = newList;

  }
