## Date Formatter |
||||
|
||||
### Instructions |
||||
|
||||
Write a class `DateFormatter` that has three private attributes: |
||||
* `date`: the date to be formatted (as a date). |
||||
* `format`: the format to convert the date to. |
||||
* `formattedDate`: contains the date converted into the given format. |
||||
|
||||
Create getters for all the attributes and setters for `date` and `format`. The conversion should happen when you set the `format` or the `date`. If the `format` is not correct, the conversion shouldn't happen. Additionally, create methods to output the date in the specified `format`, and constructors with only the `date`, with `date` and `format`, and a default constructor. |
||||
|
||||
#### The accepted date formats are: |
||||
- `DD/MM/YYYY` |
||||
- `DD Month YYYY` |
||||
- `DD.MM.YYYY` |
||||
|
||||
|
||||
#### The accepted date formats are: |
||||
- `DD/MM/YYYY` |
||||
- `DD Month YYYY` |
||||
- `DD.MM.YYYY` |
||||
|
||||
|
||||
|
||||
### Expected Functions |
||||
|
||||
```java |
||||
import java.text.SimpleDateFormat; |
||||
import java.util.Date; |
||||
|
||||
public class DateFormatter { |
||||
private long timestamp; |
||||
private String formattedDate; |
||||
private String format; |
||||
|
||||
... |
||||
} |
||||
``` |
||||
|
||||
### Usage |
||||
Here is a possible ExerciseRunner.java to test your class: |
||||
|
||||
```java |
||||
public class ExerciseRunner { |
||||
public static void main(String[] args) { |
||||
DateFormatter df = new DateFormatter(1656374400, "DD/MM/YYYY"); |
||||
System.out.println(df.getFormattedDate()); |
||||
|
||||
df.setFormat("dd.MM.yyyy"); |
||||
System.out.println(df.getFormattedDate()); |
||||
|
||||
df.setDate(1672531200); |
||||
System.out.println(df.getFormattedDate()); |
||||
|
||||
df.setFormat("DD month yyyy"); |
||||
System.out.println(df.getFormattedDate()); |
||||
} |
||||
} |
||||
``` |
||||
|
||||
### Expected Output |
||||
```shell |
||||
Copy code |
||||
$ javac *.java -d build |
||||
$ java -cp build ExerciseRunner |
