Java实现冒泡排序动画展示

public class JavaTest {
    public static void main(String[] args) {
        int[] arr = new int[]{23,1,67,-4,0,-2,90,213,-77,56,43,7,-89};
        //排序总共arr.length-1轮（数组元素个数减一）
        for (int i = 0;i < arr.length-1;i++){
            //每轮当中前后两两对比
            for (int j = 0;j < arr.length - 1 - i;j++){
                //从小到大排序
                if (arr[j] > arr[j+1]){
                    int temp = arr[j];
                    arr[j] = arr[j+1];
                    arr[j+1] = temp;
                }
            }
        }
        //输出展示排序结果
        for (int i = 0;i <arr.length;i++){
            System.out.print(arr[i] + "\t");
        }
    }
}
