Accessing variables from another classes with setter and getter JAVA

Question

This is a very simple example of my project which is a lot more bigger in scale.

Tasks:

• The password will be set at the setpassword method.

• The getpassword method will return the password.

• The password is called at sendmail class in order to be send via email to the user to log in with the new credentials.

But When I run the whole code everything works except that the sendmail class won't access the password from the getpassword method in users class.

I put a simple version of my code:

users class >>>>>

public class  users {


private String password;


public users (){}

// GETTING PASSWORD
public String getpassword(){

    return password;
}


// SETTING PASSWORD
 public void setapassword(String password){
     this.password=password;
 }




}

Signup class>>>>>>

public class signup {

public void signsup(){

    users  user1 =new users();
    user1.setapassword("player"); 

    sendmail mail1 =new sendmail();
    mail1.Sendsmail();

}
}

sendmail class>>>>

public class sendmail   {

public void  Sendsmail(){

    users user1 =new users(); // object

    user1.getpassword(); //getting password 

 System.out.println(user1.getpassword()); // If print here I get null
 }
 }

Main signup Class>>>>

public class SignupMain {

public static void main(String[] args) {

     signup signup1= new signup();
     signup1.signsup();
   }

 }

Answer 1

Please follow the standard coding conventions. I changed your code with standard coding conventions. just copy paste it , it will work

Users class

public class  Users {
private String password;
public users (){}
// GETTING PASSWORD
public String getpassword(){

    return password;
}
// SETTING PASSWORD
 public void setapassword(String password){
     this.password=password;
 }
}

Signup class

public class Signup {

public void settingPassowrd(){

    Users  user1 =new Users();
    user1.setapassword("player"); 

    SendMail mail1 =new SendMail(user1);
    mail1.Sendsmail();

}
}

SendMail class

public class SendMail   {
    private Users user1;
    SendMail(Users user1){
        this.user1 = user1
    }
    public void  sendMail(){
    user1.getpassword(); //getting password 
    System.out.println(user1.getpassword()); // If print here I get null
}
}

Main class to test the code

 public class SignupMain {

public static void main(String[] args) {

 Signup signup1= new Signup();
 signup1.settingPassowrd();
}

}
