Question

I wanna want to pass or share data(values) from login frame to all frames in my project, H have made class of this variables like this

public class SharedData {

    public  String LoginName;

    public SharedData() {
    }

    /**
     * @return the LoginName
     */
    public String getLoginName() {
        return LoginName;
    }

    /**
     * @param LoginName the LoginName to set
     */
    public void setLoginName(String LoginName) {
        this.LoginName = LoginName;
    }
}

and from the first frame (login frame) I make object of this class and sets its username like this

 public  SharedData  data1=new SharedData();
    data1.setLoginName(Username_Login.getText().toString());

and from the second frame i get the value :

public  SharedData  data=new SharedData();
ogin_labelName.setText(data1.getLoginName().toString());

But finally it doesn’t work … what is the problem or any solution ?

thanks in advance

You can create a bean class like :

public class SharedData {
        public  static String LoginName;

        public static void setLoginName(String LoginName) {
            SharedData.LoginName = LoginName;
        }

        public static String getLoginName() {
            return LoginName;
        }
    }

And use this class for setting and getting a values from another form just calling this class for setting a value:

SharedData.setLoginName(Username_Login.getText().toString());

and for getting a value :

ogin_labelName.setText(SharedData.getLoginName(Username_Login.getText().toString()));
