Question

Write a program that meets the following requirements:

Cat Class

1. Create a class called Cat which has only the following instance variables:

- name

- breed

- number of legs

- year born

2. Create the no-argument constructor
3. Create the constructor which uses all fields as parameters
4. Write the getter and setter methods for all instance variables
5. Override the toString method using the example shown above

There should be NO main method in the Cat class.

CatTester Class

1. Create a class called CatTester which constructs 10 different Cat objects
2. Add each Cat object to an array
3. Use an enhanced for loop to SOP each Cat reference
4. Use a second for loop to SOP only those Cats that are born after 2004 and have legs greater than 3

• You should use the class names of Cat and CatTester

If you have any doubts, please give me comment...

public class Cat{

private String name;

private String breed;

private int noOfLegs;

private int year;

public Cat(){}

public Cat(String n, String b, int nLegs, int y){

name = n;

breed = b;

noOfLegs = nLegs;

year = y;

}

/**

* @return the name

*/

public String getName() {

return name;

}

/**

* @return the breed

*/

public String getBreed() {

return breed;

}

/**

* @return the noOfLegs

*/

public int getNoOfLegs() {

return noOfLegs;

}

/**

* @return the year

*/

public int getYear() {

return year;

}

/**

* @param name the name to set

*/

public void setName(String name) {

this.name = name;

}

/**

* @param breed the breed to set

*/

public void setBreed(String breed) {

this.breed = breed;

}

/**

* @param noOfLegs the noOfLegs to set

*/

public void setNoOfLegs(int noOfLegs) {

this.noOfLegs = noOfLegs;

}

/**

* @param year the year to set

*/

public void setYear(int year) {

this.year = year;

}

public String toString(){

return "Name: "+name+"\tBreed: "+breed+"\tNo. of legs: "+noOfLegs+"\tYear of born: "+year;

}

}

public class CatTester{

public static void main(String[] args) {

Cat cats[] = new Cat[10];

cats[0] = new Cat("cat1", "breed 1", 4, 2005);

cats[1] = new Cat("cat2", "breed 2", 3, 2014);

cats[2] = new Cat("cat3", "breed 3", 5, 2005);

cats[3] = new Cat("cat4", "breed 4", 4, 2009);

cats[4] = new Cat("cat5", "breed 5", 4, 2004);

cats[5] = new Cat("cat6", "breed 6", 5, 2006);

cats[6] = new Cat("cat7", "breed 7", 3, 2010);

cats[7] = new Cat("cat8", "breed 8", 3, 2012);

cats[8] = new Cat("cat9", "breed 9", 5, 2008);

cats[9] = new Cat("cat10", "breed 10", 4, 1994);

//all cats:

System.out.println("All Cats: ");

for(Cat c: cats){

System.out.println(c);

}

System.out.println("Cats that are born after 2004 and have legs greater than 3");

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

if(cats[i].getYear()>2004 && cats[i].getNoOfLegs()>3){

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

}

}

}
