How to write a method that reads particular content in an array lists and count the number of array's content

Question

I am a new learner and I should create a method that will make this program work with no problems at all so I can get the final result that should look like this:

3 is 3
Mark is Mark
Richard is Richard

Here is the code (PLEASE read the comments I wrote in the code)

public class Main {

/*I wrote the following method (Student) but I keep get some issues:
Please help I spend many days and I can't figure it out and I am runnung out
of time as I should understand the problem or at least the correction that I
can read and figure out what I was doing wrong.*/

// My written code starts here
public static String Student(String[] sx){
int counter = 0;
for (int i = 0; i < sx.length; i ++){
if (sx[i] != null) counter ++;
}
return counter;
sx = new String[counter];
}
// My written code ENDS here

// From this point I should preserve the code without any changes
static Student studentA;
static Student studentB;
static Student studentC;

public static void main(String[] args) {
studentA = new Student("Mark", "John", "Jimmy");
studentB = new Student("Will", "George", "Androw");
studentC = new Student("Frank", "Sam");
int totalStudents = Student.getTotalStudents();
System.out.println(totalStudents + " is 3");
System.out.println(studentA.getFirstName() + " is Mark");
studentA.setFirstName("Richard");
System.out.println(studentA.getFirstName() + " is Richard");
}
}

Answer 1

Mohammad Ala Tahhan You can do like this

import java.util.*;

public class Program
{
public static void main(String[] args) {
Student a = new Student("Anant");
Student b = new Student("AJ");

List<Student> l = new ArrayList<Student>();

l.add(a);
l.add(b);

System.out.println("No of Student = " + l.size());

for(Student s : l) {
System.out.println("Student Name : " + s.getName());
}
}
}

class Student {
private String name;

public Student(String name) {
this.name = name;
}

public void setName(String name) {
this.name = name;
}

public String getName() {
return name;
}
}

Answer 2

Mohammad Ala Tahhan You can make a list of objects and get the Number of students.

ArrayList<Student> sl = new ArrayList<Student>();

sl.add(studentA);
sl.add(studentB);
sl.add(studentC);

int totalStudents = sl.size();

Thanks a lot for you time and explanation dear AJ #Infinity Love.

Answer 4

Thanks AJ #Infinity Love
It seems helpful but I really don't know how to apply that, and I still don't know what did I do wrong in my code!

I can't really think right now and I don't have much time to figure out how to apply your solution

Answer 5

Yes Rithea this is my whole code
