Short 基本数据类型short 的包装类
Short 类型的对象包含一个 short 类型的字段

属性简介
| 值为 215-1 的常量，它表示 short 类型能够表示的最大值 public static final short MAX_VALUE = 32767; |
| 值为 －215 的常量，它表示 short 类型能够表示的最小值 public static final short MIN_VALUE = -32768; |
| 用来以二进制补码形式表示 short 值的比特位数 public static final int SIZE = 16; |
| 二进制补码形式表示 short 值的字节数 public static final int BYTES = SIZE / Byte.SIZE; |
|
表示基本类型 short 的 Class 实例 public static final Class<Short> TYPE = (Class<Short>) Class.getPrimitiveClass("short"); |
构造方法
照常两种形式
基本类型/parseShort 按照10进制解析

常用方法
比较
|
static int compare(short x, short y)
静态方法
x<y 小于0
x=y 等于0
x>y 大于0

parseXXX系列
字符串解析 为 基本类型,
不需要对象,所以都是静态方法
![image_5bb07fe4_3f74[4]](https://img2018.cnblogs.com/blog/897393/201809/897393-20180930155203704-1898600602.png "image_5bb07fe4_3f74[4]")
parseShort系列依赖Integer.parseInt

valueOf系列
把基本基本类型 包装为对象
用来创建获得对象,所以无需对象,全都是静态方法
![image_5bb07fe4_67ee[3]](https://img2018.cnblogs.com/blog/897393/201809/897393-20180930155204949-1222930529.png "image_5bb07fe4_67ee[3]")
VaueOf系列都有对应的缓存区, 缓存区范围内对象为同一个
缓冲区为静态内部类中的数组

XXXValue系列
获取对象的某种基本类型的值
需要获取对象的所以必然全部都是实例方法
![image_5bb07fe4_7709[3]](https://img2018.cnblogs.com/blog/897393/201809/897393-20180930155207303-876718.png "image_5bb07fe4_7709[3]")
强制类型转换的形式,将内部的 short 值转换为指定的类型
| 类似 Integer和Long Byte Short也有提供XXXValue系列方法,原理也跟他们类似 全部都是强转 |
|
byteValue()
shortValue()
intValue()
longValue()
floatValue()
doubleValue()
|
toUnsignedXXX 系列
toString 系列

其他方法
Short提供了reverseBytes(short) 方法
Short虽然比Byte稍微提供的支持多一点点,但是也很少
有些方法也是依赖于Integer
