Student Class file
I used primitive and reference variable type for my student class.
public class Student {
int id_number;
String student_name;
String dob;
int grade_level;
}
App.java file
I created one student object and stored user input.
import java.util.Scanner;
public class App {
public static void main( String[] args ) {
Scanner sc = new Scanner(System.in);
String[] infoArray = {"ID Number: ", "Student Name: ", "Date Of Birth: ", "Grade Level: "};
System.out.println("Please provide information below.");
System.out.println(infoArray[0] +"\n" + infoArray[1]+"\n"+ "i.e 02/06/1981\n" + infoArray[2] +"\n"+ infoArray[3]);
Student s1 = new Student();
s1.id_number = sc.nextInt();
s1.student_name = sc.nextLine();
s1.dob = sc.nextLine();
s1.grade_level = sc.nextInt();
System.out.println( infoArray[0] + s1.id_number + "\n" + infoArray[1] + s1.student_name + "\n" + "i.e 02/06/1981");
System.out.println( infoArray[2] + s1.dob + "\n"+ infoArray[3] + s1.grade_level);
}
}
Output:
I'm not really sure why it gives me an error when I press enter right after I input the Date of Birth. I'm new to classes and objects so I would appreciate if someone explained to me what I did wrong.
Please provide information below.
