Too many cats

Report a typo

Let's count cats! Implement a class named Cat and a static method getNumberOfCats.

These are some features of the class:

  • The class Cat has two instance fields: a string name and an int age, and one static int field counter. The static counter field allows you to know how many cats have already been created.
  • The class should have a constructor for initializing the instance fields. During the initialization of a new cat, the value of the static field counter should be incremented. If counter > 5, the message "You have too many cats" must be printed to System.out.

Your static method getNumberOfCats returns the current number of created cats and prints no messages.

Take a look at the example:

Let's assume seven instances of the class Cat have already been created. Then the correctly implemented method Cat.getNumberOfCats() should return 7.

Note that the message "You have too many cats" should appear twice: the first time when creating the sixth cat and the second time when creating the seventh cat.

Use the provided template and do not make the class private.

Write a program in Java 17
class Cat {

// write static and instance variables

public Cat(String name, int age) {
// implement the constructor
// do not forget to check the number of cats
}

public static int getNumberOfCats() {
// implement the static method
}
}
