Question

In my login class I get the users name. Then in my report class I try to retrieve that name. I have used breakpoints when I enter the users name in login the string appears correct. However, when I try to access it from the report class the function from login then returns a null string. I have looked around on stack and used google and am pretty sure I am following what I am supposed to do but it is not working.

Here is some code from login. I can show more code if needed, but when I use breakpoints in login, the dName is always the correct name, and so is driversName. But when I come back to returnName from report, driversName is then a null string. I have declared driversName as a global and not local variable in my class.

private void getDriversName(String dName)
{
    driversName=dName;
}

public String returnName()
{
    return driversName;

}

Here is the code from report. Once again I can add more id needed. Also I imported login correctly. I used breakpoints and when I used the step in, it took me to login. name is coming back null.

   LogIn login;
   login=new LogIn();
   String name= login.returnName();
   driver.setText(name);

UPDATE: I figured it out I needed to add static.

Answer 1

Are you calling getDriversName function before calling login.returnName(); as from your code it is visible that driversName will have value right after getDriversName function call.

Further you can implement other approach for login and other tasks i.e. keep a common class which maintains all such sessions. You can set values once you login and then get them any where in your whole project. Like

Common.getUserName()
{
    return USERNAME;
}

and call this function after login success.

Common.setUserName(String name)
{

this.USERNAME= name;

}

Hope this will help.
