Java数组之冒泡排序
public class BubbleSort {
public static void main(String[] args) {
int[] array = {64, 34, 25, 12, 22, 11, 90};
System.out.println("Original Array:");
printArray(array);
bubbleSort(array);
System.out.println("\nSorted Array:");
printArray(array);
}
public static void bubbleSort(int[] arr) {
int n = arr.length;
boolean swapped;
for (int i = 0; i < n - 1; i++) {
swapped = false;
for (int j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
// 交换相邻的两个元素
int temp = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = temp;
swapped = true;
}
}
// 如果某一趟遍历没有发生交换,说明数组已经有序,可以提前结束排序
if (!swapped) {
break;
}
}
}
public static void printArray(int[] arr) {
for (int num : arr) {
System.out.print(num + " ");
}
System.out.println();
}
}
