You want to track the number of students enrolled. Modify your Student class to include that variable and a method to get it. Your running class should:

1. Display the current number of students enrolled; that is, print the number of students after each instance is created, along with new student information

2. You are to create one more student, taking data from the user.

THE CODE IS CREATED BASED ON THE QUESTION below

Define a class of Students with the following properties and actions: a string name, an integer age, a Boolean variable indicating whether or not the student is an IT major, and a character gender.

The default value for name is an empty string, for age is 0, for the Boolean variable is false, and for the gender is \u0000.

To compute the students age, the year of birth and the current year must be provided.

The students name and gender are set to the values provided.

To set the Boolean value, the students major must be provided. If it is IT, the Boolean variable is set to true; otherwise, it is set to false.

A student can change major. In such situation, the new major must be provided. If it is IT, the Boolean variable is set to true; otherwise, it is set to false.

import java.time.LocalDate;

class Student

{

private String name;

private int age;

private Boolean IT_major;

private char gender;

public static int num; //static variable for number of students

public Student() //default constructor

IT_major = false;

gender = '\u0000'; num++;

}

public Student(String name,char gender) //parameterized constructor

{

this.name = name;

this.gender = gender ;

num++;

}

public void setAge(int Birth_year,int Current_year) //set age by sending birth year and current year

{

age = Current_year - Birth_year;

}

public int getAge()

{

return age;

}

public void setIT_Major(String major)

{

IT_major = Is_IT_major(major); //call Is_IT_major()

}

public boolean Is_IT_major(String major) //check if student is IT_major

{

return true;
