这篇博客主要讲解了UCB的CS61B Data Structures课程中关于Java的数据类型。它区分了原始类型（如byte、int、char等）和引用类型，详细阐述了变量声明、赋值操作（等于号的含义）、类实例化、引用类型变量声明以及参数传递的过程。此外，还讨论了数组与IntList等链式数据结构的区别，强调数组大小固定而列表可以动态增长。

Primitive Types
Each Java type has a different way to interpret the bits:
eg. 72 stored as 01001000
Letter H stored as 01001000
primitive types in Java
- byte
- short
- int
- long
- float
- double
- boolean
- char
Declaring a Variable
When you declare a variable of a certain type in Java:
- Your computer sets aside exactly enough bits to hold a thing of that type.
- Java creates an internal table that maps each variable name to a location.
- Java does NOT write anything into the reserved boxes.
The Golden Rule of Equals
Given variables y and x:
- y = x copies all the bits
