本文实例讲述了java对数组进行排序的方法。分享给大家供大家参考。具体如下:
- 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("排序前:");
- showArray(a);
- int[] b = bubbleSort(a);
- System.out.println("排序后:");
- showArray(b);
- }
- }
执行结果:
排序前:
12 24 25 4 9 68 45 7
排序后:
4 7 9 12 24 25 45 68
希望本文所述对大家的java程序设计有所帮助。
