```
public final class Primitives
extends Object
```
Contains static utility methods pertaining to primitive types and their corresponding wrapper types.

所有方法静态方法具体方法
限定符和类型	方法和说明
`static boolean`	`isPrimitive(Type type)` Returns true if this type is a primitive.
`static boolean`	`isWrapperType(Type type)` Returns `true` if `type` is one of the nine primitive-wrapper types, such as `Integer`.
`static <T> Class<T>`	`unwrap(Class<T> type)` Returns the corresponding primitive type of `type` if it is a wrapper type; otherwise returns `type` itself.
`static <T> Class<T>`	`wrap(Class<T> type)` Returns the corresponding wrapper type of `type` if it is a primitive type; otherwise returns `type` itself.

isPrimitive
```
public static boolean isPrimitive(Type type)
```
Returns true if this type is a primitive.

public static <T> Class<T> wrap(Class<T> type)

Returns the corresponding wrapper type of type if it is a primitive type; otherwise returns type itself. Idempotent.

     wrap(int.class) == Integer.class
     wrap(Integer.class) == Integer.class
     wrap(String.class) == String.class

public static <T> Class<T> unwrap(Class<T> type)

Returns the corresponding primitive type of type if it is a wrapper type; otherwise returns type itself. Idempotent.

     unwrap(Integer.class) == int.class
     unwrap(int.class) == int.class
     unwrap(String.class) == String.class
