Sort array in Java without sort method

Sort array in Java without sort method

I'll respond in English, as per your request!

Sorting an array in Java without using the built-in sort() method is a common exercise for programmers. Here's one way to do it:

public class Main {
public static void main(String[] args) {
int[] array = {4, 2, 9, 6, 5, 1, 7, 3, 8};
// Implement bubble sort algorithm
for (int i = 0; i < array.length - 1; i++) {
for (int j = 0; j < array.length - i - 1; j++) {
if (array[j] > array[j + 1]) {
int temp = array[j];
array[j] = array[j + 1];
array[j + 1] = temp;
}
}
}
// Print the sorted array
for (int i : array) {
System.out.print(i + " ");
}
}
}

This Java program sorts an integer array using a simple bubble sort algorithm. Here's how it works:

Here's how the program works:

The time complexity of bubble sort is O(n^2), where n is the number of elements in the array. This algorithm is not suitable for large datasets because it's quite slow. However, it can be useful for small arrays or when simplicity matters more than performance.

In this example, we first declare and initialize an integer array array. Then, we implement a bubble sort algorithm by iterating through each element in the array and comparing adjacent elements. If two elements are out of order, we swap them. This process continues until no more swaps are needed (i.e., the entire array is sorted).

Finally, we print the sorted array using another loop that iterates through each element and prints it to the console.

I hope this helps! Let me know if you have any questions.
