3. Create a Java class called Student with the following details as private instance variables within it. USN Name Branch Phone Write a Java program to create n number Student objects and print the USN, Name, Branch, and Phone of these objects with suitable headings.
import java.util.*;
class Student
{
private String usn;
private String name;
private String branch;
private String phoneno;
public Student()
{
usn = "";
name = "";
branch = "";
phoneno = "";
}
public Student(String pusn, String name, String branch, String phoneno) {
usn = pusn;
this.name = name;
this.branch = branch;
this.phoneno = phoneno;
}
void display() {
System.out.print("usn:" + usn + " ");
System.out.print("name:" + name + " ");
System.out.print("branch:" + branch + " ");
System.out.print("phoneno:" + phoneno + "\n");
}
}
public class StudentDemo {
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
System.out.println("How many students?");
int size = read.nextInt();
