Given a Student class, create a class with following characteristics: The class name should be ClassRoom. Private variable students array to maintain the list of Student objects. Function addStudent with input parameter name (string) and rollNo(int) adds a new student in "students" list. Method getAllStudents should return all the students in ClassRoom.
Input Jack Jones Marry where, First & Second line represent a student's name and roll number. And so on Output 1 Jack 2 -Jones 3-Marry Assume that, Maximum "students" count can be 10.
Below is the code for the driver class - DriverMain.java
import java.util.*;
//Your program will be evaluated by this DriverMain class and several test case
public class DriverMain {
public static void main(String[] args) {
String name;
int rollNo;
int n = 0;
Student[] students = new Student[10];
ClassRoom classRoom = new ClassRoom();
Scanner input = new Scanner(System.in);
while(true){
name = input.nextLine();
if(name.equals(""))
break;
rollNo = Integer.parseInt(input.nextLine());
classRoom.addStudent(name, rollNo);
n++;
}
students = classRoom.getAllStudents();
for (int i = 0; i < n; i++) {
if(students[i]!=null)
System.out.print(students[i].getRollNo() + " - " + students[i].getName());
if (i < n - 1)
System.out.println();
}
}
}
//Below is the code for the Solution.java
// NOTE - THIS IS WHERE YOU WRITE THE CODE
import java.util.*;
class Student {
private String name;
private int rollNo;
public String getName() {}
public void setName(String name) {}
public int getRollNo() {}
public void setRollNo(int rollNo) {}
};
class ClassRoom {
private int i;
private Student[] students;
public void addStudent(String name, int rollNo) {
// WRITE YOUR CODE HERE
}
public Student[] getAllStudents() {
// WRITE YOUR CODE HERE
}
};
