Question

Write the complete class for an Object IceCream. It should have the variables String name and int coldness. Include a Constructor that accepts parameters for all variables. You should also create the methods to String() and clone() with their standard behaviour as discussed in class.

Hi not sure how to do this in Java

Answer 1

Answer:

IceCream.java

=======================================

public class IceCream implements Cloneable {

//variable declaration

String name;

int coldness;

//constructor

public IceCream(String name, int coldeness) {

this.name = name;

this.coldness = coldeness;

}

//toString()

public String toString() {

return "IceCream [name=" + name + ", coldness=" + coldness + "]";

}

//clone()

public Object clone() throws CloneNotSupportedException {

return super.clone();

}

}

==========================  

Main.java

==========================

public class Main {

public static void main(String[] args) throws CloneNotSupportedException {

IceCream ic = new IceCream("Vanilla",-2);

//calling toString()

System.out.println(ic.toString());

//Calling clone()

IceCream ic2 = (IceCream)ic.clone();

//assigning values

ic2.name = "Chocolate";

ic2.coldness = -20;

System.out.println(ic2.toString());

}

}

Screenshot for reference understanding:
