need help with java.

Create a Farm class

Included methods:

Farm()

Farm(int cows,int chickens, int sheep)

setAnimals(int cows,int chickens, int sheep)

getCows()

getChickens()

getSheep()

addCows(int num)

addChickens(int num)

addSheep(int num)

removeCows(int num)

removeChickens(int num)

removeSheep(int num)

equals(Farm)

toString()

You will create a farm class that will create the farm object. This farm object will contain 3 ints that store the values of the number of cows, chickens, and sheep.

Part 2: create a tester class

Using the testFarm class create tests that will make sure that your Farm works as intended. The basic outline of the class is already given to you, make sure your output matches what is given to you.

public class Farm {

/*

* class properties: one for the cows, chickens, and sheep

*/

private int cows;

private int chickens;

private int sheep;

/**

* this constructor will create a farm object with no animals ( 0 of each animal)

*/

public Farm() {

cows = 0;

chickens = 0;

sheep = 0;

}

/**

* @param cows - number of cows

* @param chickens - number of chickens

* @param sheep - number of sheep

*

* this constructor will create a farm object with the specified

* number of each animals

*/

public Farm(int cows, int chickens, int sheep) {

setAnimals(cows, chickens, sheep);

}

/**

* @param cows

* @param chickens

* @param sheep

*/

void setAnimals(int cows, int chickens, int sheep) {

this.sheep = sheep;

this.chickens = chickens;

this.cows = cows;

}

/**

* @return

*/

int getCows() {

return cows;

}

/**

* @return

*/

int getChickens() {

return chickens;

}

/**

* @return

*/

int getSheep() {

return sheep;

}

/**

* @param num

*/

void addCows(int num) {

cows += num;

}

/**

* @param num

*/

void addChickens(int num) {

chickens += num;

}

/**

* @param num

*/

void addSheep(int num) {

sheep += num;

}

/**

* @param num

*/

void removeCows(int num) {

cows = Math.max(0, cows - num);

}

/**

* @param num

*/

void removeChickens(int num) {

chickens = Math.max(0, chickens - num);

}

/**

* @param num

*/

void removeSheep(int num) {

sheep = Math.max(0, sheep - num);

}

/**

* @param farm

* @return will return a boolean that states weather the farm

* has the same exact number of each chickens, cows, and sheep

*/

boolean equals(Farm farm) {

return (cows == farm.cows && chickens == farm.chickens && sheep == farm.sheep);

}

/**

* will return a String in the form

* "x cows, y chickens, z sheep"

* where x, y, and z are the respective number of each animals

*/

public String toString() {

return String.format("%d cows, %d chickens, %d sheep", cows, chickens, sheep);

}

}

this is what I have right now. I know have to make another class but I do not know how.
