Question

I am having trouble figuring out how to To-Do list using java. Can anyone guide me through the steps for achieving this?

CODE

import java.util.ArrayList;

class Task {

private String message;

private boolean done;

public Task(String message, boolean done) {

super();

this.message = message;

this.done = done;

}

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public boolean isDone() {

return done;

}

public void setDone(boolean done) {

this.done = done;

}

}

class ToDoList {

private ArrayList<Task> tasks;

public ToDoList() {

this.tasks = new ArrayList<>();

}

public void addTask(String message) {

Task t = new Task(message, false);

tasks.add(t);

}

public void markDone(String message) {

for(Task t : tasks) {

if (message.equalsIgnoreCase(t.getMessage())) {

t.setDone(true);

}

}

}

public void displayPendingTasks() {

for (Task t : tasks) {

if (!t.isDone()) {

System.out.println(t.getMessage());

}

}

}

public void displayCompletedTasks() {

for (Task t : tasks) {

if (t.isDone()) {

System.out.println(t.getMessage());

}

}

}

}

public class Main {

public static void main(String[] args) {

ToDoList list = new ToDoList();

list.addTask("Laundry");

list.addTask("Pick up groceries");

list.markDone("laundry");

System.out.println("List of pending tasks: ");

list.displayPendingTasks();

System.out.println("List of completed tasks: ");

list.displayCompletedTasks();

}

}
