Comment rechercher des éléments dans une ArrayList? - Java

J'ai créé un programme To-Do-List en java où vous pouvez ajouter, supprimer et afficher des tâches avec des noms, des dates, des heures spécifiques, etc.

Cependant, j'essaie d'ajouter une option où, lorsque l'utilisateur sélectionne "5", il peut entrer une date et si des tâches tombent à cette date particulière, elles seront répertoriées.

Par exemple:

----------------------
Main Menu
----------------------
1. Add a task
2. Delete a task
3. Delete all tasks
4. List all tasks
5. Search for a task
6. Exit the program

Enter choice: 5

Enter a date: 20/10/2020

Here are the tasks for 20/10/2020:

-task1-
-task2-
etc...

Jusqu'à présent, lorsque je fais cela, aucune tâche ne revient même si elles existent à cette date spécifique.

Voici mon code jusqu'à présent: (searchTasks () est en bas du code)

import java.util.ArrayList;
import java.util.List;
import java.text.ParseException;
import java.util.Scanner; 

class Task{

private String theTitle;
private String theDate;
private String theTime;
private String theLocation;
private String theDuration;
private String theCategory;

Task(String title, String date, String time, String location, String duration, String category) {
    
    theTitle = title;
    theDate = date;
    theTime = time;
    theLocation = location;
    theDuration = duration;
    theCategory = category;
    
}

public String getTitle() {
    
    return theTitle;
}

public String getDate() {
    
    return theDate;
}

public String getTime() {
    
    return theTime;
}

public String getLocation() {
    
    return theLocation;
}

public String getDuration() {
    
    return theDuration;
}

public String getCategory() {
    
    return theCategory;
}

public String getItem() {
    
    return theTitle + ", " + theDate + ", " + theTime + ", " + theLocation + ", " + theDuration + ", " + theCategory;
}

}
