   done

3. thanks <3

4. good lecture with good example

5. it is really so helpful.

6. As I'm learing a lot from your tutorial, so,addressing you as my teacher I want to know, "for teacher3 object as there wasn't assigned any value,there output was default value for the individual data type.But without setting value of the variable, as I know there output is always be a garbage value.Then why those variables of teacher3 object output was default value?"

7. স্যার নাম করা খ্যাত এক প্রাইভেট বিশ্ববিদ্যালয়ে পড়েও কিছু শিখতে পারিনি। আপনার জাভা লেকচার গুলোই একমাত্র ভরসা। ধন্যবাদ স্যার ???

8. MashaAllah, oshadharon tutorial.

9. Great, really helpful. Thanks a lot Mr. Anisul for these effort. May Allah bless you.

10. নিজের রাতের ঘুম নষ্ট করে আপনি যাদের জন্য ভিডিও বানান তারা আপনার ভিডিও তে কন RESPONDS করে না, হা এটাই বাঙালি। স্যালুট আপনাকে স্যার, কোন স্বার্থ ছাড়া এই ভাবে ভিডিও বানানোর জন্য

11. package oop_;

    public class Test {

    public static void main(String[] args) {

    Teacher teacher1 = new Teacher("Anisul", "male", 1713545);

    teacher1.displayinformaction();
    Teacher teacher2 = new Teacher("rakib", "male", 154121);

    teacher2.displayinformaction();
    Teacher teacher3 = new Teacher();
    teacher3.displayinformaction();
    }

    }

12. package oop_;

    public class Teacher {

    String name, gender;
    int phone;

    Teacher(String n, String g, int ph) {

    name = n;
    gender = g;
    phone = ph;
    }

    Teacher() {
    System.out.println("No Value");

    }

    void displayinformaction() {

    System.out.println("Name=" + name);
    System.out.println("Phone=" + phone);
    System.out.println("Gender=" + gender);
    System.out.println();
    }

    }
