.3.Write a java code to create a class with data members name, category, doj, and fees and static members total_fee, categorywise_no_students, methods to Insert data using parameterized constructor, display student information along with total fees and number of students in each category.

 class StudentClassWithMultipleMethods
{
    public static void main(String arg[])
    {
        Student s1 = new Student("Raj1","SC","1/2/2021",1000);
         Student s2 = new Student("YUVA","GM","1/2/2021",2000);
         Student s3 = new Student("RAM","GM","1/2/2021",3000);

         s1.displayInfo ();
        s2.displayInfo ();
        s3.displayInfo ();

        Student.displaySummary();
    }
}
