## Day Of Week
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a class `DayOfWeekFinder` that provides a method to find the date of the next specified day of the week from a given date. The date will be provided in the format `yyyy-MM-dd`, and the day of the week will be provided as a string (e.g., "Monday", "Tuesday").
|
||
|
|
|
||
|
|
### Expected Class
|
||
|
|
|
||
|
|
```java
|
||
|
|
import java.time.DayOfWeek;
|
||
|
|
import java.time.LocalDate;
|
||
|
|
import java.time.format.DateTimeFormatter;
|
||
|
|
import java.time.format.DateTimeParseException;
|
||
|
|
|
||
|
|
public class DayOfWeekFinder {
|
||
|
|
public String findNextDayOfWeek(String startDate, String dayOfWeek) {
|
||
|
|
...
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible `ExerciseRunner.java` to test your class:
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class ExerciseRunner {
|
||
|
|
public static void main(String[] args) {
|
||
|
|
DayOfWeekFinder finder = new DayOfWeekFinder();
|
||
|
|
|
||
|
|
// Test case 1
|
||
|
|
String startDate1 = "2023-06-22";
|
||
|
|
String dayOfWeek1 = "Monday";
|
||
|
|
System.out.println("Next " + dayOfWeek1 + " after " + startDate1 + ": " + finder.findNextDayOfWeek(startDate1, dayOfWeek1));
|
||
|
|
|
||
|
|
// Test case 2
|
||
|
|
String startDate2 = "2023-06-22";
|
||
|
|
String dayOfWeek2 = "Friday";
|
||
|
|
System.out.println("Next " + dayOfWeek2 + " after " + startDate2 + ": " + finder.findNextDayOfWeek(startDate2, dayOfWeek2));
|
||
|
|
|
||
|
|
// Test case 3
|
||
|
|
String startDate3 = "2023-06-22";
|
||
|
|
String dayOfWeek3 = "Sunday";
|
||
|
|
System.out.println("Next " + dayOfWeek3 + " after " + startDate3 + ": " + finder.findNextDayOfWeek(startDate3, dayOfWeek3));
|
||
|
|
|
||
|
|
// Error case: invalid date format
|
||
|
|
String startDate4 = "invalid-date";
|
||
|
|
String dayOfWeek4 = "Monday";
|
||
|
|
System.out.println("Next " + dayOfWeek4 + " after " + startDate4 + ": " + finder.findNextDayOfWeek(startDate4, dayOfWeek4));
|
||
|
|
|
||
|
|
// Error case: invalid day of the week
|
||
|
|
String startDate5 = "2023-06-22";
|
||
|
|
String dayOfWeek5 = "Funday";
|
||
|
|
System.out.println("Next " + dayOfWeek5 + " after " + startDate5 + ": " + finder.findNextDayOfWeek(startDate5, dayOfWeek5));
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Expected Output

|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
|
||
|
