How do you add objects from keyboard inputs into an array wi

How do you add objects from keyboard inputs into an array with a loop in java?

I am trying to store 5 student\'s data (name, id, test1 and test2, average, and letter grade) from my Student class into an array.

Solution

StudentTest.java

import java.util.Scanner;

public class StudentTest {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       Student s[] = new Student[5];
      
       for(int i=0; i<s.length; i++){
           System.out.print(\"Enter the student name: \");
           String name = scan.next();
           System.out.print(\"Enter the student id: \");
           int id = scan.nextInt();
           System.out.print(\"Enter the student exam1: \");
           int exam1 = scan.nextInt();
           System.out.print(\"Enter the student exam2: \");
           int exam2 = scan.nextInt();
           System.out.print(\"Enter the student letter grade: \");
           char letterGrade = scan.next().charAt(0);
           s[i] = new Student(id, name);
           s[i].setExam1(exam1);
           s[i].setExam1(exam2);
           s[i].setLetterGrade(letterGrade);
           s[i].setAverage((exam1+ exam2)/2);
       }
       for(int i=0; i<s.length; i++){
           System.out.println(\"Student Name: \"+s[i].getName());
           System.out.println(\"Student Id: \"+s[i].getId());
           System.out.println(\"Student Exam1: \"+s[i].getExam1());
           System.out.println(\"Student Exam2: \"+s[i].getExam2());
           System.out.println(\"Student Average: \"+s[i].getAverage());
           System.out.println(\"Student Letter Grade: \"+s[i].getLetterGrade());
           System.out.println(\"*****************************************\");
           System.out.println();
       }
   }

}

Student.java

public class Student {
   private String name;
   private int id;
   private int exam1;
   private int exam2;
   private double average;
   private char letterGrade;
   public Student(int id, String name){
       this.id = id;
       this.name = name;
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public int getId() {
       return id;
   }
   public void setId(int id) {
       this.id = id;
   }
   public int getExam1() {
       return exam1;
   }
   public void setExam1(int exam1) {
       this.exam1 = exam1;
   }
   public int getExam2() {
       return exam2;
   }
   public void setExam2(int exam2) {
       this.exam2 = exam2;
   }
   public double getAverage() {
       return average;
   }
   public void setAverage(double average) {
       this.average = average;
   }
   public char getLetterGrade() {
       return letterGrade;
   }
   public void setLetterGrade(char letterGrade) {
       this.letterGrade = letterGrade;
   }
  
}
