Question

2-1. Define and implement a class named cart. A cart object represents a horse drawn cart that can seat up to four meerkats, after that meerkats have to walk. The meerkats must be represented by meerkat objects. The cart class has the following constructors and behaviours: cort)i bool addleerkat(meerkat cat); vold enptyCort() void printMeerkats0 // create an erpty cart object // dd, ?"eerkat to the cart, returns false if full // renove all reerkats from the core print the nane, space,the age, then a new line for eech seerkat in the order they were added Your main program should create a cart object and 5 meerkat objects. The cart object is initially empty. Your main program must then add all 5 meerkat objects to the cart object. An appropriate error message must be printed by your main program when the cart is full

Answer 1

//meerkart class
public class meerkart
{
string name; //I just add name for example.if you wish you add other properties and functions
meerkart(string name)
{
this.name=name;
}
}
// cart class
public class cart{
static int count=0; //a static object to add only four meerkart

String[] m=new String[4];//I use array as I take only name in meerkart class, you can use 
// list or collection or other datatype for detailed program
cart() //cart constructor
{} 
boolean addMeerkat(meerkat cat) // adding a meerkart to the cart

{

if (count>5) //check the count

{

m[count+1]=cat.name;

return 1; ///return boolean value

}

else return 0;

}

void emptyCart() //check weather the cart is empty or not

{

if(count==0)

  System.out.println("Cart is empty");

else

  System.out.println("Cart is not empty");

}

void printMeerkats() // print meerkart names added to the cart
{
for(int i=0;i<=count;i++)

  System.out.println(m[i]+",  ");

}
   public static void main(String[] args)  //main funtion
   {
      System.out.println("WELCOME");
      cart c1=new cart(); //cart object
      cart c2=new cart();
      meerkart m1=new meerkart("cat"); //meerkart objects
      meerkart m2=new meerkart("dog");
      meerkart m3=new meerkart("pig");
      meerkart m4=new meerkart("cow");
      meerkart m5=new meerkart("duck");

int i =c1.addMeerkat(meerkat m1);

if (i==0)

System.out.println(" Meerkat added successfully to the cart 1");

else

System.out.println(" Sorry, Something went wrong.");

i =c1.addMeerkat(meerkat m2);

if (i==0)

System.out.println(" Meerkat added successfully to the cart 1");

else

System.out.println(" Sorry, Something went wrong.");

i =c1.addMeerkat(meerkat m3);

if (i==0)

System.out.println(" Meerkat added successfully to the cart 1");

else

System.out.println(" Sorry, Something went wrong.");

i =c1.addMeerkat(meerkat m4);

if (i==0)

System.out.println(" Meerkat added successfully to the cart 1");

else

System.out.println(" Sorry, Something went wrong.");

i =c1.addMeerkat(meerkat m5);

if (i==0)

System.out.println(" Meerkat added successfully to the cart");

else

System.out.println(" Sorry, Something went wrong.");

c1.emptyCart();
System.out.println("Meerkats in cart 1 - ");
c1.printMeerkats();
   }

}

OUTPUT:

WELCOME

Meerkat added successfully to the cart 1

Meerkat added successfully to the cart 1

Meerkat added successfully to the cart 1

Meerkat added successfully to the cart 1

Sorry, Something went wrong.

Cart is not empty

Meerkats in cart 1 - cat, dog, pig, cow,
