冒泡排序

 private void swap(int[] arrays, int i, int j) { int temp; temp = arrays[i]; arrays[i] = arrays[j]; arrays[j] = temp; } public int[] arrayIntSort(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]) { swap(array, j, j + 1); } } } return array; }

快速排序

private void quickSort(int[] array, int start, int end) { int left = start; int right = end; if (left < right) { int temp = array[left]; while (left != right) { while (left < right && temp <= array[right]) right--; array[left] = array[right]; while (left < right && temp >= array[left]) left++; array[right] = array[left]; } array[right] = temp; quickSort(array, start, left - 1); quickSort(array, right + 1, end); } }

c++冒泡排序写法

void swap(jint *arrays, int i, int j) {int temp;temp = arrays[i];arrays[i] = arrays[j];arrays[j] = temp;
}JNIEXPORT jintArray JNICALL
Java_com_cpf_ndkdemo_MainActivity_arrayIntSortByNative(JNIEnv *env, jobject instance,jintArray array_) {jint *array = env->GetIntArrayElements(array_, NULL); int length = env->GetArrayLength(array_); for (int i = 1; i < length; i++) { for (int j = 0; j < length - i; j++) { if (array[j] > array[j + 1]) { swap(array, j, j + 1); } } } jintArray jintArray = env->NewIntArray(length); env->SetIntArrayRegion(jintArray, 0, length, array); env->ReleaseIntArrayElements(array_, array, 0); return jintArray; } 

c++快速排序写法

void fastSort(jint *array, jint start, jint end) {int left = start;int right = end;if (left < right) { int temp = array[left]; while (left != right) { while (left < right && temp <= array[right]) right--; array[left] = array[right]; while (left < right && temp >= array[left]) left++; array[right] = array[left]; } array[right] = temp; fastSort(array, start, left - 1); fastSort(array, right + 1, end); } } JNIEXPORT jintArray JNICALL Java_com_cpf_ndkdemo_MainActivity_arrayFastIntSortByNative(JNIEnv *env, jobject instance, jintArray array_, jint start, jint end) { jint *array = env->GetIntArrayElements(array_, NULL); fastSort(array, start, end); jintArray jintArray = env->NewIntArray(end + 1); env->SetIntArrayRegion(jintArray, 0, end + 1, array); env->ReleaseIntArrayElements(array_, array, 0); return jintArray; } 

快速排序波动大，冒泡排序更稳定，数据量越大快速排序速度优势越明显；

在数据大多数顺序正确的情况下冒泡排序可能更快，而数据越混乱快速排序越快；
