All of the work in this project is my/our own! I/We have not left copies of my code in public folders on university computers. I/We have not given any of this project to others. I will not give any portion of this project to others taking this class. I realize that the penalty for turning in work that is not my own can range from an "F" in the class to dismissal from Trinity University.

IntArray 1 Lab
Individual/Team (1-2 Persons) Assignment
30 Points

1] Copy your Stack class to a file called IntArray1.java

2] Replace every occurrence of top with actNo.

3] We are going to create our own Integer Array class. You may not use any of the built in Java Array or Vector processing tools for this lab.

4] Your private data is to be

	private int [] info;
	private int actNo;
	private boolean sorted;
	private int max;

5] Write the constructor

IntArray1(int maxElements)

which

creates and info array of maxElements + 1 integers

initializes the actNo to 0 [you are   to place the first value in element[1] of the array

initializes the max to maxElements [do not allow to be negative]

```
initialize sorted to be false.
```

6] Write functions

void Display ();
void Display(String message)

which

```
display the optional message
```

display a nice graphical output in the form

       Message
       |----------------------------------------------------|
    3 |                                                1232 |
       |----------------------------------------------------|
    2 |                                                 331 |
       |----------------------------------------------------|
    1 |                                                5555 |
       |----------------------------------------------------|
       actNo = 3                  max = 5               sorted = false

Write function

void QuickAndDirtyDisplay (message);

which

```
display the optional message
```

displays the actno, max, and sorted flags

displays the numbers in 8 character blocks, ten to a line

       Message
       actNo = 22                  max = 500               sorted = false

      12       233         1        13       28       1111       122          2       211         21
     332       213       221      4223        8          1        22        333       111        221
     111        18

6] Write function   // use the one from your stack program - modify slightly

void Resize (int changeAmount);

which

alters the size of the array, either up or down, by the changeAmount

do not ever make the array smaller than the actNo and loose data

```
do not ever make the array <= 0 in size
```

7] Write function

void FillRandom (int noToFill, int low, int high);

which

places noToFill random integers, in the range low to high, into the info array 
starting with element 1

```
make the array bigger if necessary
```
```
do not make the array smaller
```

8] Write function

void FillFromFile (String FileName);

which

```
opens the file
```

places the values from the file into the info array [don't know how many there are] starting
with element 1

```
make the array bigger if necessary
```
```
do not make the array smaller
```

9] Write function

int SequentialHigh ();

which

explicitly returns the highest value in the unsorted array

10] Write function

int SequentialLow ();

which

explicitly returns the lowest value in the unsorted array

11] Write function

double Mean ();

which

explicitly returns the arithmetic mean of the elements in the array

12] Write function

int Sum ();

which

explicitly returns the arithmetic sum of the elements in the array

13] Write function

int TestIntArray1 ();

which

fully tests each of the functions above

your test module might start something like :

public static void TestIntArray1() 
{
    System.out.println("======================    Test Default Constructor ===========================");
   
    IntArray1 nos1 = new IntArray1();
    nos1.Display("Contents of nos1");

   System.out.println("======================    Test Normal Constructor ============================");
   IntArray1 nos2 = new IntArray1(4);
   nos2.Display("Contents of nos2");

   IntArray1 nos3 = new IntArray1(-4);
   nos3.Display("Contents of nos3");

   System.out.println("======================    Test Sum ===========================================");
   
   nos1.info[1] = 5;
   nos1.info[2] = 15;
   nos1.info[3] = 10;
   nos1.actNo = 3;
   nos1.Display("Contents of nos1 = 5 15 10 ");
   System.out.println("Sum = " + nos1.Sum());
	
   // You Do

}

14] Document each and every module for javadocs

15] Those Labs labeled "Individual Assignment" are to be done separately by each individual. Using a pen, each individual is to print his/her name at the top of this document in the space provided and sign it. Those Labs labeled "Team Assignment" may be done as a team or individually. Using a pen, each individual on the team is to print print his/her name at the top of this document in the space provided and sign it. Submit only one copy of team assignments!
