This exercise implements the class Student and then a main that adds each Student into an ArrayList that can be entered and searched.
My Code
Main
import java.util.ArrayList;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// write here the main program
Scanner input = new Scanner(System.in);
ArrayList<Student> list = new ArrayList<Student>();
System.out.print("name: ");
String name = input.nextLine();
while (name.length() > 0) {
System.out.print("studentnumber: ");
String number = input.nextLine();
Student student = new Student(name, number);
list.add(student);
System.out.print("name: ");
name = input.nextLine();
}
for (Student student : list) {
System.out.println(student);
}
System.out.print("Give search term: ");
String search = input.nextLine();
System.out.println("Result: ");
for (Student student : list) {
if (student.getName().contains(search)){
System.out.println(student);
}
}
}
}Student
public class Student {
private String name;
private String studentNumber;
public Student(String name, String studentNumber){
this.name = name;
this.studentNumber = studentNumber;
}
public String getName(){
return this.name;
}
public String getStudentNumber(){
return this.studentNumber;
}
public String toString() {
return getName() + " (" + getStudentNumber() + ")";
}
}Model Code

}
System.out.print("studentnumber: ");
String number = reader.nextLine();
list.add(new Student(name, number));
}
for (Student student : list) {
System.out.println(student);
}
System.out.println();
System.out.print("Give search term: ");
String searchTerm = reader.nextLine();
System.out.println("Result:");

That went well.
