老师为什么我这个Tread是红色的

我没有给 “jacymin”这个用户分配unlimited tablespace 这个权限，也可以创建table呢？

这么多语言，由浅入深应该是什么呢？

先学习和了解的，然后进阶的顺序是什么？

int a = new Random().nextInt(4);

swtich (Season.value()[a]){...}

中的[a]是什么用法和下方的case打印什么关系

这是为什么啊

老师请问为什么左边文件目录看不到我的项目文件夹，这是另一个文件夹，听课写代码的文件夹不是这个，怎么调出来呢？

就是这样按视频说的写的,注释里面写代码,但是取不到结果输出的是${a+b}

var adder =function (a,b) {
    return 'this num of the 2 numbers ${a+b}'
}

console.log(adder(5,3))

老师，Idea绑定的Maven中已经有setting配置文件，那这个路径中setting文件起作用嘛，我发现把它删了项目也不会报错啊。

老师 为啥我的工作目录换成e盘 创建文件就创建不了 d盘就可以

老师 请问这里的第五条_比较运算操作是什么呢?

onmouseleave和onmouseout有什么区别
