百炼成神之冒泡排序练习

Posted 2021-04-07 JAVA基础到实战

import java.util.Arrays;
public class TestDemo { public static void bubbleSort(int[] arr){ int tem;//定义一个临时变量 for (int i=0;i<arr.length-1;i++){ for (int j=0;j<arr.length-i-1;j++){ if (arr[j+1]<arr[j]){ tem = arr[j]; arr[j]=arr[j+1]; arr[j+1]= tem; } } } }
 public static void main(String[] args) { int arr[] = new int[]{1,6,3,2,5}; bubbleSort(arr); System.out.println(Arrays.toString(arr)); }}
