This article describes the method of sorting arrays by Java. Share it for your reference. The details are as follows:
public class Test1 { public static void showArray(int[] array) { for (int n = 0; n < array.length; n++) { System.out.print(array[n]); System.out.print(" "); } System.out.println(); } public static int[] bubbleSort(int[] before) { int t; for (int i = 0; i < before.length; i++) { for (int j = 0; j < before.length - i - 1; j++) { if (before[j] > before[j + 1]) { t = before[j]; before[j] = before[j + 1]; before [j + 1] = t; } } } return before; } public static void main(String[] args) { int[] a = { 12, 24, 25, 4, 9, 68, 45, 7 }; System .out.println("before sorted:"); showArray(a); int[] b = bubbleSort(a); System.out.println("before sorted:"); showArray(b); } }Execution results:
Before sorting:
12 24 25 4 9 68 45 7
After sorting:
4 7 9 12 24 25 45 68
I hope this article will be helpful to everyone's Java programming.
