FOOD SUPERCLASS 2 SOLUTIONS

TASK – PART 1 – SETUP – FOOD CLASS

No solution required.

TASK – PART 2 – SANDWHICH CLASS

Here is my solution:

public class Sandwhich extends Food

{

private String breadType;

private String toppings;

private String spreads;

public Sandwhich (String n, int a, String u, String f, String bt, String t, String s)

{

super(n, a, u, f);

breadType = bt;

toppings = t;

spreads = s;

}

public String toString()

{

return name + " on " + breadType + " bread";

}

}

TASK – PART 3 – SANDWHICH TESTER

Here is my solution:

public class SandwhichTester

{

public static void main(String[] args)

{

Sandwhich s1 = new Sandwhich("Club house", 4, "triangles", "savoury", "sourdough", "bacon, tomatoes, turkey & lettuce", "mayo");

System.out.println(s1);

System.out.println("*****");

System.out.println("LUNCH MENU");

Food[] lunch = new Food[5];

lunch[0] = s1;

lunch[1] = new Sandwhich("PB&J", 2, "halves", "sweet", "white", "", "peanut butter & jam");

lunch[2] = new Food("Soup", 2, "cups", "savoury");

lunch[3] = new Food("Soda crackers", 4, "pieces", "savoury");

lunch[4] = new Food("Carrots", 5, "sticks", "sweet");

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

{

System.out.println(lunch[i]);

}

}

}

And this is the toString() in Food that I changed:

@Override

public String toString()

{

return name;

}

And this is the output:

Club house on sourdough bread

*****

LUNCH MENU

Club house on sourdough bread

PB&J on white bread

Soup

Soda crackers

Carrots
