I want with help of inputs be able to search for the objects aswell and print them out. I dont know if this is on the right way and would love some help.

import java.util.Scanner;

import java.util.ArrayList;

public class JAVA extends LIBRARY { private String author;

public JAVA(String Name, long ISBN) {
    super(Name, ISBN);
    this.author = author;

}


public static void main(String[] args) {
    JAVA myAPP = new JAVA();
    Scanner scan = new Scanner(System.in);
    ArrayList<LIBRARY> persons = new ArrayList();
    persons.add(new LIBRARY("Harry Potter", 111111));
    persons.add(new LIBRARY("Sagan om ringen", 222222));
    persons.add(new LIBRARY("Pet Cemetary", 333333));

    int LÖS = 1;
    int input;


    System.out.println("Välkommen till Hkr Biblotek!");
    System.out.println("Tryck 1 för att söka böcker 2 för att avsluta");
    input = scan.nextInt();
    if (LÖS == 1) {




        myAPP.inputBok(input);
    } else if (LÖS > 1) {
        System.exit(2);
    }


}

public String inputBok(int a) {
    Scanner scan = new Scanner(System.in);
    String input;
    long input1;
    System.out.println("Skriv in bokens namn!");
    switch (scan.nextInt()) {

        case 1:


            input = scan.nextLine();

        case 2:

            System.out.println("Skriv in bokens ISBN nummer!");
            input1 = scan.nextLong();
        case 3:
            System.out.println("Denna bok kostar");
            System.out.println("Det finns även böcker med liknade titlar");

    }
    return inputBok(a);

}

} public class LIBRARY {

public final long ISBN;
public final String NAME;


public LIBRARY(String Name, long ISBN) {
    this.NAME = Name;
    this.ISBN = ISBN;

}

public String getNAME() {
    return NAME;
}

public long getISBN() {
    return ISBN;


}

public String toString() {
    return "LIBRARY{" + NAME + ISBN;


}
