Answers:
Simple java class can be defined such as Student.java. Then, you can define class with main method such as Driver.java. In the Driver class you can create array of objects of Student class. Each Student object can be initialized in the loop.
public class Student {
int id;
String name;
}
Driver.java
import java.util.Scanner;
public class Driver {
public static void main (String args[]) {
Student st[];
st = new Student[3];
Scanner sc = new Scanner(System.in);
for(int i= 1; i<3; i++) {
st[i] = new Student();
System.out.println("Enter Id: ");
st[i].id = sc.nextInt();
System.out.println("Enter Name: ");
st[i].name =sc.next();
}
System .out.println("Print the Results");
for(int i=1; i<3; i++) {
System.out.println(st[i].id);
System.out.println(st[i].name);
}
}
}
