you sir have just got another subscriber. beautiful explanation and I wrote so many lines of code until you showed how to simply used those three attributes for ALL of the student objects instead of making one attribute for each object. definitely i am going to check out all of your other videos too. thank you.

More precise way for(Student s: students) { System.out.println(s.name + ":" + s.mark); }

So array is going to store objects values in place of objects ?? Basically in a array each element consists of 3 different student values

What is the difference b/w array of objects and collection functionality wise

@singirikumar2782 Жыл бұрын

Collection functionality wise ... If u create a object as collections U can access lot of methods to perform CRUD operations on data Which is in collection..nd also growable in nature size wise nd it follows some data Structures...i.e data in some order ..ascending or descending but if u create object as array ...it is fixed u cannot add new data and u cannot delete and allows it won't follow data structures When ever u r requirement is fixed heterogenous data and no need of delete of data .. we will go for Object array ..

Is the length property a static attribute of the array object?

I got it solved, by creating a class using Student. Below is the code class Student{ String name=""; int age= 0; }

Getting error when Student class is not Static. But Navin didn't have it as static. What am I doing wrong?

public static void main(String[] args) use this if showing error

public class Main{ public static void main(String[] args) { Student stud = new Student(); stud.roll = 1; stud.marks = 88; stud.name = "Kevin"; Student stud2 = new Student(); stud2.roll = 2; stud2.marks = 78; stud2.name = "Marco"; Student stud3 = new Student(); stud3.roll = 3; stud3.marks = 90; stud3.name = "Justin"; Student[] students = new Student[3];//Array with references students[0] = stud;//Manual objects students[1] = stud2; students[2] = stud3; for (Student student : students) { System.out.print(student.name + " " + student.roll + " " + student.marks + " "); } } } class Student { int roll; int marks; String name; }

I have two doubts here, 1.When we create an object the class name should be same 2. When we create the three student objects you didnt intialize the data types for rollno, name, marks. If anyone knows please rectify my doubts. Thanks in advance

@SPragnasya 11 ай бұрын

Okay let me address your doubts: 1. Yes, when you create an object in Java, the class name should be the same. For example: Imagine you have a class called Student. If you want to make an actual student object, you say Student st = new Student();. This naming consistency helps others (and yourself) easily understand what type of object is being created. class Student { // Class definition } Student st = new Student(); // Creating an object of the Student class 2. Coming to your second doubt, consider the below example : class Student { int rollNo; String name; double marks; } public class Main { public static void main(String[] args) { Student st1 = new Student(); st1.rollNo = 1; st1.name = "John"; st1.marks = 90.5; Student st2 = new Student(); st2.rollNo = 2; st2.name = "Jane"; st2.marks = 85.0; } } In the Student class, you have defined three instance variables: int is the data type for rollNo, String for name, and double for marks. These are the data types for the respective fields. In the Main class, you are creating two instances of the Student class (st1, st2) and initializing the data for each object. Hope you understood 😊!
