Task List:

1- primitive type -> byte bit

> native 关键字 

 

2- primitive type, reference type --> stack , 堆

3-stringBuffer stringBuilder 

 4-sealed, 没有关键字怎么处理

5-int， long的取值范围。。什么时候考虑大数字问题

6-why you cannot cast between Iterable<String> and Iterable<Object>, check out covariance and contravariance.
