Question about the task

Under discussion

package com.codegym.task.task02.task0204; /* Family relations */ public class Solution { public static void main(String[] args) { // Woman Woman = new Man(); Man Man = new Woman(); Man.wife = Woman; Woman.husband = Man; } public static class Man { public int age; public int height; public Woman wife; } public static class Woman { public int age; public int height; public Man husband; } }

In the main method, create a Man object and save a reference to it in the variable man.
Also, create a Woman object and save a reference to it in the variable woman.

Hint: Use the following construct to create a Woman object and assign a reference to that object to the variable woman:
VariableType variableName = new TypeOfObjectBeingCreated();
Save a reference to the previously created Woman object in man.wife.
Save a reference to the previously created Man object in woman.husband (Hint: woman.husband = man).

Requirements:

In the main method, create a Man object and save a reference to it in the variable man.
In the main method, create a Woman object and save a reference to it in the variable woman.
In the main method, store a reference to the previously created Woman object in man.wife.
In the main method, store a reference to the previously created Man object in woman.husband.
The Man class must have 3 variables.
The Woman class must have 3 variables.

Line 10: Woman woman = new Woman(); Line 11: Man man = new Man(); Man / Woman with capital letter is for class declaration. It is not the same as man / woman. Java is case sensitive, be careful. Also, class declarations must match:

Man variableName = new Man();

Such mistakes will be much easier to track once you start working in IntelliJ (lesson 3).

Now it looks like below but still does not work: Woman woman = new Woman(); Man man = new Man(); Man.wife = Woman; Woman.husband = Man;

Man is the type of the object and man the object identifier. So if you want to address an instance variable of a certain object, you have to use the object identifier. That's what Agent Smith named variableName So man.wife would be correct and the same for the part after the equals sign. Woman is the type and woman the identifier, the object. So altogether it's man.wife = woman;
