?冒泡排

import java.util.Arrays;

//测试冒泡排序以及优化
public class TestBubbleSort {

        int temp=0;

            boolean flag=true;
            for (int j = 0; j < values.length - 1-i; j++) {//找最大
                //比较大小 换顺序
                if (values[j] > values[j + 1]) {
                    temp = values[j];
                    values[j] = values[j + 1];
