class msg {
    void data() {
        String name, dep, age, bdg, hob;
        System.out.println("\nStudent data .....:)");
        System.out.print("\nEnter your name:");
        Scanner a = new Scanner(System.in);
        name = a.nextLine();
        System.out.print("\nEnter your department:");
        Scanner b = new Scanner(System.in);
        dep = b.nextLine();
        System.out.print("\nEnter your age:");
        Scanner c = new Scanner(System.in);
        age = c.nextLine();
        System.out.print("\nEnter your blood-group:");
        Scanner d = new Scanner(System.in);
        bdg = d.nextLine();
        System.out.print("\nEnter your hobbies:");
        Scanner e = new Scanner(System.in);
        hob = e.nextLine();
    }

    void showdata() {
        System.out.println("\nStudent data inserted successfully .....:)");
        System.out.println("Name :" + name);
        System.out.println("Department :"+dep);
        System.out.println("Age :"+age);
        System.out.println("Blood-Group :"+bdg);
        System.out.println("Hobbies :"+hob);
    }
}

public class display {
    public static void main(String[] args) {
        msg d=new msg();
        d.data();
        d.showdata();
        System.out.println("Welcome to java development !!!");
    }
}

How do I call these variables – > name, dep, age, bdg, hob – > inside the method showdata() and print that details, is there any option to call another variable of another method in a different method but in the same class

defaultjava.java:32: error: cannot find symbol
     System.out.println("Name:"+name);
     ^
  symbol:   variable name
  location: class msg
