推荐答案

From java.lang.Class.isPrimitive API

From java.lang.Class.isPrimitive API

有九个预定义的Class对象来表示八种原始类型和无效。它们由Java虚拟机创建，并且与它们表示的基本类型具有相同的名称，即boolean，byte，char，short，int，long，float和double。

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 the primitive types that they represent, namely boolean, byte, char, short, int, long, float, and double.

这些对象只能通过以下公共静态最终变量访问 java.lang.Boolean.TYPE ， java.lang.Integer.TYPE etc

These objects may only be accessed via the following public static final variables java.lang.Boolean.TYPE, java.lang.Integer.TYPE etc
