Interface for Sorting Objects in Java

Write a Java program to demonstrate the use of an interface for sorting a list of objects

The Sortable interface defines a method sort for sorting an array of type T.
The BubbleSort class implements the Sortable interface and provides a generic bubble sort algorithm to sort arrays of elements that implement the Comparable interface.
In the Main class, arrays of integers and strings are created.
Instances of BubbleSort are created for sorting integer and string arrays.
The sort method is called on these instances to sort the arrays.
Finally, the sorted arrays are printed to the console.

Source Code

import java.util.Arrays;
 
interface Sortable<T>
{
	void sort(T[] arr);
}
 
class BubbleSort<T extends Comparable<T>> implements Sortable<T>
{
	@Override
	public void sort(T[] arr)
	{
		int n = arr.length;
		for (int i = 0; i < n - 1; i++)
		{
			for (int j = 0; j < n - i - 1; j++)
			{
				if (arr[j].compareTo(arr[j + 1]) > 0)
				{
					T temp = arr[j];
					arr[j] = arr[j + 1];
					arr[j + 1] = temp;
				}
			}
		}
	}
}
 
public class Main
{
	public static void main(String[] args)
	{
		Integer[] intArray = {5, 1, 4, 2, 8};
		String[] strArray = { "cherry", "banana", "date", "apple"};
 
		System.out.println("Given Integers : " + Arrays.toString(intArray));
		System.out.println("Given Strings : " + Arrays.toString(strArray));
 
		BubbleSort<Integer> intSorter = new BubbleSort<>();
		BubbleSort<String> strSorter = new BubbleSort<>();
 
		intSorter.sort(intArray);
		strSorter.sort(strArray);
 
		System.out.println("Sorted Integers : " + Arrays.toString(intArray));
		System.out.println("Sorted Strings : " + Arrays.toString(strArray));
	}
}

Output

Given Integers : [5, 1, 4, 2, 8]
Given Strings : [cherry, banana, date, apple]
Sorted Integers : [1, 2, 4, 5, 8]
Sorted Strings : [apple, banana, cherry, date]
