The correct data type depends on your needs. I'm unsure why you'd use a HashMap as a first choice though. What would be your key and value respectively?

ok so this is the script

package edu.ntnu.iir.bidata;

import java.time.LocalDate;

public class Grocery {
private final String name; // Name of the item.
private double quantity; // The quantity of the items.
private double weight; // The weight of the item.
private double price; // The price of the item.
private String unit; // The measuring unit of the weight (kg, ml, gm).
private LocalDate bestBeforeDate; // The best-before date of the item.

// Constructor
public Grocery(String name, double quantity, double weight, double price, String unit, LocalDate bestBeforeDate) {
    this.name = name;
    this.quantity = quantity;
    this.weight = weight;
    this.price = price;
    this.unit = unit;
    this.bestBeforeDate = bestBeforeDate;
}

// Getters and setters
public String getName() {
    return name;
}

public double getQuantity() {
    return quantity;
}

public void setQuantity(double quantity) {
    this.quantity = quantity;
}

public double getWeight() {
    return weight;
}

public void setWeight(double weight) {
    this.weight = weight;
}

public double getPrice() {
    return price;
}

public void setPrice(double price) {
    this.price = price;
}

public String getUnit() {
    return unit;
}

public void setUnit(String unit) {
    this.unit = unit;
}

public LocalDate getBestBeforeDate() {
    return bestBeforeDate;
}

public void setBestBeforeDate(LocalDate bestBeforeDate) {
    this.bestBeforeDate = bestBeforeDate;
}

// Utility methods
@Override
public String toString() {
    return "Grocery{" +
            "name='" + name + '\'' +
            ", quantity=" + quantity +
            ", weight=" + weight +
            ", price=" + price +
            ", unit='" + unit + '\'' +
            ", bestBeforeDate=" + bestBeforeDate +
            '}';
}

// Example of checking if the item is past its best-before date
public boolean isPastBestBeforeDate() {
    return LocalDate.now().isAfter(bestBeforeDate);
}

// Example of calculating total cost based on quantity
public double calculateTotalCost() {
    return quantity * price;
}

// Example of displaying formatted weight
public String getFormattedWeight() {
    return weight + " " + unit;
}

}

the is the grocery class

this is the gui

That doesn't really answer my question, and what if I buy the same good two times with a different expiration date?

I am also unsure what you mean with will be saved only for 1 session. Regardless of the data type the data will be gone if you do not persist it in some manner.
