hi

Question about the task

Under discussion

I need help with regards to the code. I have done it in two different ways and it is either ,i miss the fourth requirement or i miss the last requirement .I do not know if i have to apply the equal() method. Any information with explanation would be appreciated.

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.

Requirements:

The Cat class must contain only one fullName variable.
The variable fullName must be a String and have a private access modifier.
The Cat class must have only two methods: setName and main.
The setName method must have a local variable fullName.
The Cat class's setName method must set the value of the global private String variable fullName equal to the local variable fullName.

package com.codegym.task.task04.task0406; /* Name register */ public class Cat { private String fullName; public void setName(String firstName, String lastName) { String fullName= firstName + " " + lastName; //write your code her System.out.println(fullName); } public static void main(String[] args) { Cat obj = new Cat(); obj.setName("Henry","McQuincy"); } }

i think you should see what the fourth requirement wants,what is the prrvate variable,and what is the local variable

1st way - what you're trying to do here is initialising an Instance variable fullName with local variable firstName , lastName without initialising it like :- this.fullName = firstName + lastName; . try to initialize Instance variable using this keyword. 2nd Way :- Since Instance Variables are available throughout the class scope through object(s), therefore, they are also available in setName() method. In setName() , you've declared the fullName variable again and made it a local variable. If you hadn't declare it as a local variable then your task would've completed. Don't declare fullName again.

remember to read the theory thoroughly. Here's the hint for you: 1. the main purpose of the setName method is to assign the passed values(firstName, lastName) to the instance variable of the object (fullName), and got nothing to do with System.out.println. 2. Try using 'this' keyword. If you still can't figure it out, just tell me imma give you my code.
