Final answer:
The detailed answer includes Java code for two generic bubble sort methods, one using Comparable and the other using Comparator, along with a main method to test these sorting methods with an array of 10 integers.
Step-by-step explanation:
The question pertains to writing two generic methods in Java for sorting an array using bubble sort - one using the Comparable interface, and the other using a Comparator. Here is the Java code that accomplishes this, along with a program to test the sorting with an array of 10 integers:
import java.util.Comparator;
public class BubbleSortTest {
public static > void bubbleSort(E[] list) {
E temp;
boolean swapped;
for (int i = 0; i < list.length - 1; i++) {
swapped = false;
for (int j = 0; j < list.length - 1 - i; j++) {
if (list[j].compareTo(list[j + 1]) > 0) {
temp = list[j];
list[j] = list[j + 1];
list[j + 1] = temp;
swapped = true;
}
}
if (!swapped) break;
}
}
public static void bubbleSort(E[] list, Comparator comparator) {
E temp;
boolean swapped;
for (int i = 0; i < list.length - 1; i++) {
swapped = false;
for (int j = 0; j < list.length - 1 - i; j++) {
if (comparator.compare(list[j], list[j + 1]) > 0) {
temp = list[j];
list[j] = list[j + 1];
list[j + 1] = temp;
swapped = true;
}
}
if (!swapped) break;
}
}
public static void main(String[] args) {
Integer[] numbers = {35, 23, 48, 12, 56, 44, 2, 49, 19, 37};
bubbleSort(numbers);
for (int number : numbers) {
System.out.print(number + " ");
}
System.out.println();
bubbleSort(numbers, Comparator.naturalOrder());
for (int number : numbers) {
System.out.print(number + " ");
}
}
}
This example uses an array of integers which is a common data type for demonstrating sorting algorithms. You can replace Integer with any other Comparable objects to test the generic methods.
