how to get the date from a class to the test class

here is what i have to do, and what I have already did
After a quick meeting with the head of the company, you got the following information:
It is required to store the whole data in one collection
Each flight has a number, a pilot and a specific date. In addition, passengers could be added or removed within a given limit for the maximum number of passengers who could be in the same flight. Furthermore, there are other attributes (add at least 3 attributes from your choice). Of course, flight number is unique within the same date.
Each pilot has a unique ID, a name and other attributes (add at least 2 attributes from your choice).
Each passenger has a unique passport number, a name and other attributes (add at least 2 attributes from your choice but one of them should be common with pilots).
Moreover, you have been informed that the following operations happen frequently:
Offering a new flight
Adding a passenger to a specified flight
Removing a passenger from a specified flight  Retrieving the average number of passengers per flight of a specified date
Displaying all available flights in a format similar to the following: date1: flightNo1 flightNo2 flightNo3 … date2: flightNo1 flightNo2 flightNo3 … … where dates and flights are sorted in ascending order
Saving all the data into a text file
this is what did
I am starting the test class and when I started I for some reason couldn't get the date so I tried a shitty way and I don't think I am right

i'm here to learn but i had a time limit so with the case of using Local time, I don't want to use code that I still don't understand yet so I just continued with what I did, it kinda sucked how I had to make a new object for each time but it's wasn't too bad and I finished the main method.
here it is(of course this isn't the last version as i added many more variables and commands but i just wanted to give you the final draft before i finished it completely.

Apache Flink Job execution fails whenever delete change log in received from Debezium MySql CDC

I have implemented Debezium MySql connector with Apache Flink. I am able to receive CDC event through Kafka. Insert and update event are working fine.But as soon as delete event is received, Flink job and application stops working with Job execution failed exception error. Delete event is received in my code and sink invoke method is getting triggered and my delete query is running successfully but after completion Flink job is stopped with error message Job execution failed. Not aware if it is a bug in Flink or any configuration is not right. I have attached my Flink main configuration class and Sink class.

JPA 2.2: Using find method to retrieve data from mysqlDB

I´m using JPA 2.2(Openjpa) running on OpenLiberty and mysqlVer 15.1 Distrib 10.1.21-MariaDB.
I have an object call Account where I use the entityManager.find to retrieve a given record.
The record is indeed retrieved but only this column "status" returns null.
But when I do the manual select against the DB,the value is there.

Inherited method not working

I have a method that is supposed to replenish stock parts for a manufacturer. I have tried using super.Method() but its not working. There's also a class called Part if it's needed.
Main Class
package main;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class TestAssembledPart {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
List<AssembledPart> aparts = new ArrayList<AssembledPart>();
aparts.add(new AssembledPart("a200", "Crank & Pedal", 10, 3.5, "Crank", "Pedal"));
System.out.println("part before stock level change - start");
System.out.println(AssembledPart.toAssembledString(aparts));
for (AssembledPart apart: aparts){
if(apart!=null){
System.out.println("Please enter replenish quantity");
aparts.replenish(sc.nextInt());
}
}
System.out.println("part before stock level change - end");
System.out.println(AssembledPart.toAssembledString(aparts));
}
}
AssembledPart Class
package main;
import java.util.*;
public class AssembledPart extends Part {
private String basica;
private String basicb;
private int assembledstocklevel;
public AssembledPart(String id, String name, int stocklevel, double unitprice,
String basica, String basicb) {
super(id, name, stocklevel, unitprice);
this.basica = basica;
this.basicb = basicb;
}
public void replenish(int qty){
super.replenish(qty);
//super.stocklevel = super.stocklevel + qty;
}
public String toAssembledString() {
return super.toString() + " | " + basica + " | " + basicb;
}
public static String toAssembledString(Collection<AssembledPart> aparts){
String s = "";
for (AssembledPart apart: aparts){
s += apart.toAssembledString() + "\n";
}
return s;
}
}
PartClass
package main;

public class Part {

Replace this line :
aparts.replenish(sc.nextInt());
With the following
apart.replenish(sc.nextInt());
You were actually calling a method on the collection that contains your objects instead of the objects themself.

getting NULL in setter and getter - JAVA

i always end up with this error "Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException" when im running my program. i have Member Class where i code my setter and getter. All the entities i need id there. now i have another method in "Admin Class"
public class Admin {
private ArrayList<Member> members;
private String AccessName;
private String username;
private String password;
public Admin(){
this.AccessName="Ms. April Santos";
this.username = "estella";
this.password = "teller";
this.members = new ArrayList<Member>();
}
public ArrayList<Member> getMembers() {
return members;
}
public void setMembers(ArrayList<Member> members) {
this.members = members;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getAccessName() {
return AccessName;
}
public void setAccessName(String AccessName) {
this.AccessName=AccessName;;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
#Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Admin other = (Admin) obj;
if ((this.username == null) ? (other.username != null) : !this.username.equals(other.username)) {
return false;
}
return true;
}
#Override
public int hashCode() {
int hash = 7;
hash = 97 * hash + (this.username != null ? this.username.hashCode() : 0);
return hash;
}
#Override
public String toString() {
return "Admin{" + "members=" + members + ", AccessName;=" + AccessName + ", username=" + username + ", password=" + password + '}';
}
public Member searchMember(Member member){
return this.searchMember(member.getMemberId());
}
public Member searchMember(String memberId){
for(Member member : this.members){
if(member.getMemberId().equals(memberId)){
return member;
}
}
return null;
}
public Member addMember(Member member){
if (this.searchMember(member) == null){
this.members.add(member);
return member;
}
return null;
}
public Member addMember(String memberId, String firstName,String middleName, String lastName){
if (this.searchMember(memberId) == null){
Member member = new Member(memberId, firstName,middleName, lastName);
this.members.add(member);
return member;
}
return null;
}
public boolean validateLogin(String username, String password){

}
now im calling public addMember(String memberId, String firstName,String middleName, String lastName) in my AddMemberView(GUI). im trying to get all the text in the textfield/combobox and set it so that it will be temporary saved and ready to be saved in database as i code my DAO. this is my AddMemberView btnSave action look:

thanks for your help.

I think your "admin" variable is null. Do you call your constructor? If yes, are the parameters correct?
Just write "private Admin admin" dont make the admin variable an Admin Object. Try initialize it or call the constructor properly.
