Question about the task

Creating cats

Java Syntax, Level 5, Lesson 9

Resolved

any thing is wrog in the code

Create the Cat class with five constructors:
- Name,
- Name, weight, age
- Name, age (standard weight)
- Weight, color (name, address, and age are unknown; the cat is homeless)
- Weight, color, address (someone else's pet)

The constructor's job is to make the object valid.
For example, if the weight is unknown, then you need to specify some average weight.
A cat can't weigh nothing.
The same applies to age and color. But there may or may not be a name (i.e. name might be null).
The same applies to the address (it might be null).

Requirements:

The Cat class must have a String variable name.
The Cat class must have an int variable age.
The Cat class must have an int variable weight.
The Cat class must have a String variable address.
The Cat class must have a String variable color.
The class must have a constructor that takes a name as an argument, but initializes all variables except the address.
The class must have a constructor that takes a name, weight, and age as arguments, and initializes all variables except the address.
The class must have a constructor that takes a name and age as arguments, and initializes all variables except the address.
The class must have a constructor that takes a weight and color as arguments, and initializes all variables except the name and address.
The class must have a constructor that takes a weight, color, and address as arguments, and initializes all variables except the name.

package com.codegym.task.task05.task0510;

Check the first line of your code. You are copy-pasting from other question and hence package name is wrong. For the question you are solving, replace 510 with 517. It will work.
