面向过程的语言有哪些_面向对象的语言有哪些_面向过程的语言(2)

根据java.lang.Class类的源代码，该类的注释是：

Java官方描述：

Instances of the class Class represent classes and inteces in a running Java application. An enum is a kind of class and an annotation is a kind of intece. Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same element type and number of dimensions. The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as Class objects.

参考译文：

Class类的实例表示正在运行的Java应用程序的类和接口。像枚举是一种类和注解则是一种接口。每个数组也属于被反射作为由具有相同的元素类型和尺寸的数目的所有阵列共享一类对象的类。原始的Java类型（boolean, byte, char, short, int, long, float, and double）和关键字void也表示为Class对象。

同时也根据Javadoc中对Class.isPrimitive()方法的定义，来判断

Java官方描述：

public boolean isPrimitive()

Determines if the specified Class object represents a primitive type.

There are nine predefined Class objects to represent the eight primitive types and void. These are created by the Java Virtual Machine, and have the same names as t he primitive types that they represent, namely boolean,byte, char, short, int, long, float, and double.

These objects may only be accessed via the following public static final variables, and are the only Class objects for which this method returns true.

Returns:

true if and only if this class represents a primitive type

Since:

JDK1.1

参考翻译：

public boolean isPrimitive()

判断指定的Class对象是否代表一个基本类型。

一共有9种设定好的Class对象来表示对应的基本类型和void关键字。这些对象都是由JVM创建的。

return

当且仅当该类表示一个真正的基本类型

以上都说明，在JVM内部，其实原始类型就是对象。
