Write code in the addNewCat method to increase the number of cats by 1 each time it is called.

The variable catCount corresponds to the number of cats. The Cat class must have only one catCount variable. The variable catCount must be a static int, have a private access modifier, and be initialized to zero. The Cat class must have two methods: addNewCat and main. The Cat class's addNewCat method should increase the number of cats by 1.

Requirements:

public class Cat { private static int catCount = 0; public static void addNewCat() { int cat= catCount++; System.out.println(cat); //write your code here } public static void main(String[] args) { addNewCat(); } }

Here's a second task I thought I understood this but maybe not. I'm not really sure about object creation and object referencing. I don't know why I feel lke I understood it a few months age.

Finish writing the code of the setName method so that it sets the value of private String fullName to the value of the local String variable fullName. private String fullName; public void setName(String firstName, String lastName) { String fullName = firstName + " " + lastName; this.fullName= fullName; //write your code here } public static void main(String[] args) { } }

Back to Java after abandoning it for a few weeks. I like that Codegym is repetitive. Anyway this exercise is the same as the last.

Help the cat get a name using the setName method.

Requirements:

•The Cat class must contain only one variable called name. •The variable name must be a String and have a private access modifier. •The Cat class must have only two methods: setName and main. •The Cat class's setName method must set the value of the private String variable name equal to the passed String argument name.

My solution is below

public class Cat { private String name = "nameless cat"; public void setName(String name) { this.name = name; } public static void main(String[] args) { Cat cat = new Cat(); cat.setName("Simba"); System.out.println(cat.name); } }

Task not Written Well

I’ve never wrote a negative post about Codegym but there’s a place and time for everything (this site is still the best there is imho). The instructions need clarification. The order that the input is accepted in is important. It must be number and then name (although it’s not printed like that). And while you are accepting an input by the user YOU aren’t actually inputting anything. Basically you don’t have to print statements like “put in a number”.
