java测试感受

这个星期四下午来了一次Java考试，用来测试在暑假自学Java的学习情况，不得不说这次考试十分的成功，把我对这学期的学习信心打击的很难受，我也知道这是我应得的教训，我也对我的专业水平有了很深刻的了解了，自己会什么，不会什么，在我心里都有了明确的了解，更说明了我在暑假期间所学到的那些东西，根本不足以我让我个人完成一个完整的项目，在这次考试中，我也只写了最简单的前面的部分，剩下的难点我都不会，对于这次考试，我个人感受到的只有绝望，可能也有完全会做的人，对于他来说可能写代码是一件令人能感到愉悦的事，对我来说似乎有一点难受，通过这次考试，让我知道了自己在什么水平上，以现在的水平能否在将来在IT行业中占有一席之地，在我的心里也都有了十分明确答案’，那种无力感和焦急感能让我记住很长时间，对我来说印象深刻，可能现在还没吃到因为专业水平不够的亏,但是照这样下去也就是早晚的事，对于我来说这个试卷有点难了，我承认我这次完成这个完整的代码其中是有抄袭的，不过同时也并不是抄完就完事了，我也会学习里边的结构、用法什么，但是文件的那里有点难理解，不是很明白，我个人觉的抄没什么，如果能在过程中能把他变成自己的东西就是值得的，也是一种学习的方式，肯定不适合长期这么做，如果能在以后的学习生活中不在出现这种情况，那么就是很大的进步。我也希望自己能够在专业水平上有所提高，如果可以自己独立完成，谁愿意用这种方式完成作业，所以我也买了几本书用来再去学习java的相关知识，用来提高自己的水平，让自己的有更好的水平是每个人都希望的，谁都不愿意在大学中白白浪费了这几年的时间，浪费提高自己水平的大好时光，也想完成自己在入学之前对自己的期许，不辜负任何人，这谁都想做到。

在考试结束的时候，给我测试的是一个大四的老学长，我和他聊了几句，他说他没有去那天的招聘会，他说那里给的工资太低了，他就随意的带过去了，但我在上课的时候，看见了不少去招聘的学生，每个人都穿上西装，看起来很有气势的样子，但是我一联想到他说的薪酬不高，大四的学长又说他不去，在感叹时光流逝之快的同时，我也感觉在大学接近四年的学习生活中，即使是同班同学甚至是同宿舍的那几个人之中，都会在专业水准上分出个三六九等，水平高的自然眼界也就高了，工资给的低根本不用去浪费时间，而水平不够的只能在这些给的工资水平低的公司中选择，我似乎感觉到了他们的无奈，但是却无可奈何，后悔估计也没用了，估计如果我在以后的学习生活中再浑浑噩噩的过下去，没准也和现在去招聘的学生一样，虽然说三百六十五行，行行出状元，可我已经进入了这个行列，估计以后都不会再改了，所以这只能逼着自己去学习。
