I'm a new programmer,
I'm terribly sorry for the walls of code, but I simply can't find the error.
I am tring to create an arrayList that stores input values, but everytime I create the 2nd instance, the first instance gets overwritten. It does print two instances, but both instances have the same value.
Main block: The problem area is at the bottom of this code, "switch sc1" and "switch s2, case 2"

Stream block: This block is used to inherit the properties for use in the class "List"
package com.company;
import java.time.LocalDateTime;
public class Stream {
protected String listUsername;
protected String title;
protected String genre;
protected String type;
protected double price;
protected String startTimeDate;
protected String endTimeDate;
public Stream (String listUsername, String title, String genre, String type, double price, String startTimeDate, String endTimeDate) {
this.listUsername = listUsername;
this.title = title;
this.genre = genre;
this.type = type;
this.price = price;
this.startTimeDate = startTimeDate;
this.endTimeDate = endTimeDate;
}
String genreArray[] = {"Comedy", "Lifestyle", "Music"};
String typeArray[] = {"Entertainment", "Familiy", "Work"};
public String getListUsername() { return listUsername; }
public void setListUsername(String listUsername) { this.listUsername = listUsername; }
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getGenre() {
return genre;
}
public void setGenre(String genre) {
this.genre = genre;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public String getStartTimeDate() {
return startTimeDate;
}
public void setStartTimeDate(String startTimeDate) {
this.startTimeDate = startTimeDate;
}
public String getEndTimeDate() { return endTimeDate; }
public void setEndTimeDate(String endTimeDate) { this.endTimeDate = endTimeDate;}
}
List block: I think that the main issues are here, but I just can't figure out what is wrong.
package com.company;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.ArrayList;
public class List extends Stream {
public List(String listUsername, String title, String genre, String type, double price, String startTimeDate, String endTimeDate) {
super(listUsername, title, genre, type, price, startTimeDate, endTimeDate);
}
ArrayList<Stream> joinableList = new ArrayList<Stream>();
ArrayList<Stream> completedList = new ArrayList<Stream>();
public void addJoinableList(Stream stream) {
joinableList.add(stream);
}
public void printJoinableList() {
for (Stream s : joinableList) {
System.out.print("\nUsername: " + s.getListUsername());
System.out.print("\nTitle: " + s.getTitle());
System.out.print("\nGenre: " + s.getGenre());
System.out.print("\nType: " + s.getType());
System.out.print("\nPrice: " + s.getPrice());
System.out.print("\nStart time and date: " + s.getStartTimeDate());
System.out.print("\nEnd time and date: " + s.getEndTimeDate() + "\n");
}
}
}
All help is appreciated, thank you.
