BubbleSorter
- Create package
com.benko.exercise.sort
- In that package create two clases:
SortingApp
- class with themain
method, an entry point for the applicationBubbleSorter
- having method calledsort
that implements the bubble sort algorithm
The main method should:
- create an array of integers (can be hardcoded),
- create an instance of the
BubbleSorter
- sort the array by invoking the
BubbleSorter#sort()
method of the sorter instance, and - print sorted array to the standard output.
The declaration of the sort
method should be:
void sort(int[] numbers)
Create Sorter interface
In the com.benko.exercise.sort
package please create an interface called Sorter
.
It should have just one operation: void sort(int[] numbers);
There are already two classes in that package, that should implement this interface: BubbleSorter
and DummySorter
.
Please:
- Create the interface (as mentioned above)
- Modify both *Sorter classes so that they implement newly created interface
- In SortingApp invoke sort method on interface, rather than concrete class, i.e.:
Sorter sorter = new BubbleSorter();
sorter.sort(numbers);
//etc
