GS，credit risk & interest rate front desk team。一天面了两个组。还算轻松，
一共只见了6个人。答的很一般，基本没考算法，揪着问java的东西，大部分比较基础
，但是有些地方就有点bt了，应该还是我太弱了。还是应该好好复习一下的。就当攒经
验了，move on.
记得起来的问题：
person # 1:
1. inheritance vs composition
2. what is clonable
3. what is shallow copy & deep copy. how to do deep copy without immplement
clonable
4. what is transient
5. say something about java collection framework. what are the common method
of class Collection.
6. how to immplement a hashmap. how does hashmap immplemented in |

Suppose class ClassName immplements runnable interface. Write a function
which returns a thread that attached with this class, taking the class name
string as argument.
我这么写的：
public Thread myFunction (String s) {
Thread t=null;
try {
Object o = Class.forName(s).newInstance();
t = new Thread((Runnable)o);
}
catch(Exception e ){

用dsp 会更简单一些，因为可以直接用c 编程，做计算更容易。
用FPGA 更efficient 而且可以速度更快，但你这个速度根本不需要更快得速度。

发帖数: 183 | 9 数据精度也有关系。
dsp专门用来做fft这些运算，速度应该比同频fpga或者microcontroller的快一些。
32bit已经做的很快了。除非你想把算法用硬件实现，fpga肯定是最快的。不过你的速
度要求不是那么高，如果精度不是很高的话。
