Why would it expect a interface?

Question about the task

Resolved

What is an interface or a enum? I am not there yet. class, interface, or enum expected. file com/codegym/task/task05/task0526/Solution.java, line 43, position 1083

1. Inside the Solution class, create public static Man and Woman classes.
2. The classes must have the following fields: String name, int age, String address.
3. Make constructors that have all possible parameters.
4. Create two objects of each class with complete data using a constructor.
5. Display the objects on the screen in this format: name + " " + age + " " + address

Requirements:

In the Solution class, create a public static Man class.
In the Solution class, create a public static Woman class.
The Man class must have variables: String name, int age, and String address.
The Woman class must have variables: String name, int age, and String address.
The Man and Woman classes must have constructors that take String, int, and String arguments.
The constructors must initialize the instance variables.
In the main method, you need to create two objects of each type.
The main method should display the created objects on the screen in the specified format.

package com.codegym.task.task05.task0526; /* Man and woman */ public class Solution { public static void main(String[] args) { Man man1 = new Man("Mark", 30,"W lane"); Man man2 = new Man("Kevin", 18, "Hampshire"); System.out.println(man1); System.out.println(man22); Woman woman1 = new Woman("Elane", 18, "2nd st"); Woman woman2 = new Woman("Naomi", 25, "Virginia st"); System.out.println(woman1); System.out.println(woman2); } } public static class Man{ String name; int age; String address; public void intitalize (String name, int age, String address){ this.name = name; this.age =age; this.address =address; } } public static class Woman{ String name; int age; String address; public void intitalize(String name, int age, String address){ this.name = name; this.age =age; this.address =address; } } }

This error is showing because the IDE, intelliJ, has no idea what you are trying to accomplish. It is important to realize computers do not have brains and can look at code an figure out what you mean to accomplish, such as a human with programming experience can do. This specific error is because you have one too many closing curly brackets. You will need to remove the one at either line 19 or 21 (not both) to fix that particular problem.

useful

Your next problem is that the code creating the new Man and Woman objects is calling a constructor that does not exist. There is however an initialize method in each class that is to be used for this purpose, however the code will need to call the initialize (make sure you check the spelling in the code for accuracy) method after the object is created. So, here is an example of doing that:

// first create an object
Man man1 = new Man();
// next call the initialize method with correct arguments (String, int, String)
man1.initialize("Mark", 30,"W lane");

Also make sure all the object variables in the main method are correct (man2 vs man22)

After that the output to screen needs to be specified. Passing an object to the println() method that does not have a specific toString() method over ridden in the object's class code will output that object's physical address in memory. So the output of this code (when the above are fixed) would be: com.codegym.task.task05.task0526.Solution$Man@5f184fc6 com.codegym.task.task05.task0526.Solution$Man@3feba861 com.codegym.task.task05.task0526.Solution$Woman@6f496d9f com.codegym.task.task05.task0526.Solution$Woman@723279cf This is because objects can be any infinite number of things and, once again, computers are not human and can not think cognitively to figure out what your code means to accomplish. You are going to have to figure out how to tell the computer specifically how to output the correct information (i suggest using the template in the conditions). This code should have this output: Mark 30 W lane Kevin 18 Hampshire Elane 18 2nd st Naomi 25 Virginia st When you accomplish this then the task should verify.

Thank you. I was able to get the right out put. The program is still saying it doesn't meet the criteria but I will keep trying on my own for now. Thanks again.

cause there's a cosing bracket in line 43 without the counterpart.
