冒泡排序:
package arrays; public class Sort { public static void main(String[] args) { // TODO 自动生成的方法存根 //冒泡排序 int[] array = { 63,4,24,1,3,15}; Sort sorter = new Sort(); sorter.sort(array); } public int sort(int[] array) { for(int i = 1; i < array.length; i++) { for(int j = 0; j < array.length - i; j++) { if(array[j] > array[j + 1]) { int temp = array[j]; array[j] = array[j + 1]; array[j + 1] = temp; } } } showArray(array); return 0; } public int showArray(int[] array) { for(int i: array) { System.out.print(" > " + i); } System.out.print("/n"); return 0; } }
直接选择排序
package arrays; public class SelectSort { public static void main(String[] args) { int[] array = { 63,4,24,1,3,15}; SelectSort sorter = new SelectSort(); sorter.sort(array); } public void sort(int[] array) { int index; for(int i = 1; i < array.length; i++) { index = 0; for(int j = 1; j <= array.length - i; j++) { if( array[j] > array[index]) { index = j; } } //交换在位置array.length - i 和 index(最大值)上的两个元素 int temp = array[array.length - i]; array[array.length - i] = array[index]; array[index] = temp; } showArray(array); } public void showArray(int[] array) { for(int i : array) { System.out.print(" > " + i); } System.out.println(); } }
