Java实现冒泡排序

package com.ltl.test;
public class BubbleSort {
	public static void main(String[] args) {
		//1.初始化数组
		int[] array={-4,3,8,4,12,2};
		//2.对数组进行排序
		sortBySelect(array);
		//3.打印排序结构
		printArray(array);
	}
	private static void printArray(int[] array) {
		// 对数组进行排序
		for (int i = 0; i < array.length; i++) {
			System.out.print(array[i]+" ");
		}
		System.out.println();
	}
	
	private static void sortBySelect(int[] array) {
		// 打印排序结构
		for (int i = 0; i < array.length-1; i++) {
			for (int j = 0; j < array.length-i-1; j++) {
				//降序排序
				if(array[j] < array[j+1]){
					//第三变量交换
					int temp = array[j];
					array[j] = array[j+1];
					array[j+1] = temp;
				}
			}
		}
	}
