how to use scanner in foreachloop to store the input from commandline into array
<p>Below is my code: I have defined a Student class that has last name, first name and score and get and set methods for the same as below.</p>

<p>In main I create an array of student objects. The array has to get its element value from command line.  I do not know how to use scanner in a foreach loop to store the input from the commandline into the array.</p>

<p>The main assignment is to read the 3 entries for multiple students and show the sorted output according to lastname.</p>

<pre><code>package student;

abstract class Student implements Comparable{

private String lastname;
private String firstname;
private int score;

public Student( ){

}

public void setLastname(String lastname)
{
  this.lastname= lastname;
}

public void setFirstName(String firstname)
{
    this.firstname = firstname;
}

public void setScore(int score)
{
    this.score=score;

}
public String getLastName()
{
    return lastname;
}

public String getFirstName()
{
    return firstname;
}

public int getScore()
{
    return score;
}

public int CompareTo(Object o)
{
    Student s = (Student) o;
    int comparison;
    final int EQUAL = 0;

    comparison=this.lastname.compareTo(s.lastname);
    if(comparison != EQUAL)
        return comparison;
    else comparison = this.firstname.compareTo(s.firstname);
    if(comparison!= EQUAL)
        return comparison;
    return EQUAL;

}
}

package student;


import java.util.Scanner;
import java.util.Arrays;
public class Main {

/**
 * @param args the command line arguments
 */

public static void main(String[] args) {
    // TODO code application logic here

    System.out.println("Welcome to the Students Score Application");

    System.out.print("Enter the number of Students:  ");

    Scanner sc = new Scanner(System.in);
   int num_Students = sc.nextInt();

   Student[] stu = new Student[num_Students];
   String lname ="";
   for(Student s: stu)
   {
       int count = 1;
       System.out.print("Student " + count + " Last Name: ");
      //if(sc.hasNext())
      // lname = sc.nextLine();
      // s[lname];
       System.out.println("Student " + count + "First Name: ");

      // if(sc.hasNext())
      // s.setFirstName(sc.nextLine());
       System.out.println("Student " + count + "Score: ");
      // if(sc.hasNextInt())
      // s.setScore(sc.nextInt());
       count++;
       sc.nextLine();
   }
   Arrays.sort(stu);

   for (Student s: stu)
       System.out.println(s.getLastName()+ " , " + s.getFirstName()+ ":" + s.getScore());
}

}
