Array Sorting

Array sorting is the process of arranging the elements of an array in a specific order. Sorting an array allows for easier searching, analyzing, and processing of the elements.

There are various sorting algorithms available, each with its own time and space complexity. One commonly used algorithm is the Bubble Sort algorithm.

The Bubble Sort algorithm works by repeatedly swapping adjacent elements if they are in the wrong order until the entire array is sorted.

Here's an example of how to implement the Bubble Sort algorithm in Java:

1public class BubbleSort {
2    public static void main(String[] args) {
3        int[] array = {5, 3, 8, 4, 2};
4        bubbleSort(array);
5        printArray(array);
6    }
7
8    public static void bubbleSort(int[] array) {
9        int n = array.length;
10        for (int i = 0; i < n - 1; i++) {
11            for (int j = 0; j < n - i - 1; j++) {
12                if (array[j] > array[j + 1]) {
13                    int temp = array[j];
14                    array[j] = array[j + 1];
15                    array[j + 1] = temp;
16                }
17            }
18        }
19    }
20
21    public static void printArray(int[] array) {
22        for (int i = 0; i < array.length; i++) {
23            System.out.print(array[i] + " ");
24        }
25        System.out.println();
26    }
27}

In this example, we have an array array with elements [5, 3, 8, 4, 2]. We call the bubbleSort() method to sort the array using the Bubble Sort algorithm. Finally, we print the sorted array using the printArray() method.

Bubble Sort is a simple sorting algorithm, but it has a time complexity of O(n^2), which makes it inefficient for large arrays. However, it is easy to understand and implement.

There are many other sorting algorithms available, such as Selection Sort, Insertion Sort, Merge Sort, and Quick Sort, each with its own advantages and disadvantages. It's important to choose the right sorting algorithm based on the specific requirements of your application.

To learn more about sorting algorithms and their implementations in Java, you can explore Java documentation or refer to algorithm books and online resources.

Array sorting is a fundamental topic in data structures and algorithms, and understanding different sorting algorithms is crucial for developing efficient and optimized code.

// Bubble Sort

public class BubbleSort {

    public static void main(String[] args) {

        int[] array = {5, 3, 8, 4, 2};

        bubbleSort(array);

        printArray(array);

    }

​

    public static void bubbleSort(int[] array) {

        int n = array.length;

        for (int i = 0; i < n - 1; i++) {

            for (int j = 0; j < n - i - 1; j++) {

                if (array[j] > array[j + 1]) {

                    int temp = array[j];

                    array[j] = array[j + 1];

                    array[j + 1] = temp;

                }

            }

        }

    }

​

    public static void printArray(int[] array) {

        for (int i = 0; i < array.length; i++) {

            System.out.print(array[i] + " ");

        }

        System.out.println();
