常見排序演算法介紹冒泡排序
public class BubbleSort { public static void sort(int[] array) { int tValue; for (int i = 0; i < array.length; i++) { for (int j = i; j < array.length; j++) { if (array[i] > array[j]) { tValue = array[i]; array[i] = array[j]; array[j] = tValue; } } } } public static void main(String[] args) { int a[] = { 6, 2, 4, 5, 1, 9, 10, 7 }; sort(a); for (int v : a) { System.out.print(v + " "); } }}
輸入結果:
1 2 4 5 6 7 9 10
插入排序:
public class InsertSort { public static void sort(int[] array) { int tValue; int j; for (int i = 0; i < array.length; i++) { j = i; tValue = array[i]; while (j > 0 && tValue < array[j - 1]) { array[j] = array[j - 1]; j--; } array[j] = tValue; } } public static void main(String[] args) { int a[] = { 6, 2, 4, 5, 1, 9, 10, 7 }; sort(a); for (int v : a) { System.out.print(v + " "); } }}
輸入結果:
1 2 4 5 6 7 9 10
選擇排序:
public class SelectSort { public static void sort(int[] array) { int index, tValue; for (int i = 0; i < array.length; i++) { index = i; for (int j = i + 1; j < array.length; j++) { if (array[j] < array[index]) { index = j; } } if (index != i) { tValue = array[i]; array[i] = array[index]; array[index] = tValue; } } } public static void main(String[] args) { int a[] = { 6, 2, 4, 5, 1, 9, 10, 7 }; sort(a); for (int v : a) { System.out.print(v + " "); } }}
輸入結果:
1 2 4 5 6 7 9 10
高速排序:
public class QuickSort { public static void quickSort(int[] array, int left, int right) { int i, j, bValue, tValue; if (left > right) { return; } i = left; j = right; bValue = array[left]; while (i != j) { while (array[j] >= bValue && i < j) { j--; } while (array[i] <= bValue && i < j) { i++; } if (i < j) { tValue = array[i]; array[i] = array[j]; array[j] = tValue; } } array[left] = array[i]; array[i] = bValue; quickSort(array, left, i - 1); quickSort(array, i + 1, right); } public static void main(String[] args) { int a[] = { 6, 2, 4, 5, 1, 9, 10, 7 }; quickSort(a, 0, a.length - 1); for (int v : a) { System.out.print(v + " "); } }}
輸入結果:
1 2 4 5 6 7 9 10
