How to make a Task and Todo Program in Java?

I want to make a Task and Todo program. I have written the code in separated classes. The class Task will represent a single item that needs to get done.

public class Task {
private String task;
private int priority;
private int workload;
public Task(String task, int priority, int workload) {
this.task = task; // Description of the task
this.priority = priority; // 1 = very important, 2 = important, 3 = unimportant, 4 = after learn
// Portuguese
this.workload = workload; // amount of time to complete the task
}
public String getPriority(String translation) {
if (priority == 1) {
translation = "very important";
}
if (priority == 2) {
translation = " important";
}
if (priority == 3) {
translation = "unimportant";
}
if (priority == 4) {
translation = " after learn German";
}
return translation;
}
public String toString() {
String translation = "";
return task + " takes " + workload + " minutes and has priority " + getPriority(translation);
}
}

While the class Todo will hold all the tasks organized.

public class Todo {
ArrayList<String> Todo = new ArrayList<>();
public void addTask(String description, int priority, int minutes) {
if (priority > 4 || priority < 1) {
System.out.println(description + " has invalid priority ");
}
if (minutes < 0) {
System.out.println(description + " has invalid workload ");
}
Todo.add(Task.class.getName());
}
public void getTodoList() {
Todo.forEach(item->System.out.println(Task.class.getName().toString()));
}
public void print() {
System.out.println("Todo:");
System.out.println("-----");
getTodoList();
if (Todo == null) {
System.out.println("You're all done for today! #TodoZero");
}
}
public static void main(String[] args) {
Task task;
Todo todo;
todo = new Todo();
todo.addTask("Go to gym", 2, 60);
todo.addTask("Read book", 1, 45);
todo.print();
System.out.print("");
}
}

Output:

Todo:
-----
Task
Task

But the problem is the Todo.print() method cannot print the list of tasks that have been added to Todo. The expected output should be like this:

Go to gym takes 60 minutes and has priority important
Read book takes 45 minutes and has priority very important

Your output is correct. You don't add tasks to your list, you add class name. Call Task's constructor in todo.add()

Following changes are required in your Todo Class to get the desired output

   ArrayList<Task> Todo = new ArrayList<>(); // ArrayList of Tasks
public void addTask(String description, int priority, int minutes) {
if (priority > 4 || priority < 1) {
System.out.println(description + " has invalid priority ");
}
if (minutes < 0) {
System.out.println(description + " has invalid workload ");
}
Todo.add(new Task(description, priority,minutes));   // Add Task
}
public void getTodoList() {
// Iterate over Todo ArrayList
for (Task task : Todo){
System.out.println(task);
}
}
