所有类型的Class对象

所有类型的Class对象

哪些类型可以有Class对象

代码演示

import java.lang.annotation.ElementType;

//所有类型的Class
public class Test04 {
    public static void main(String[] args) {
        Class c1 = Object.class;    //类
        Class c2 = Comparable.class;    //接口
        Class c3 = String[].class;  //一维数组
        Class c4 = int[][].class;   //二维数组
        Class c5 = Override.class;  //注解
        Class c6 = ElementType.class;   //枚举
        Class c7 = Integer.class;   //基本数据类型
        Class c8 = void.class;  //void
        Class c9 = Class.class; //Class

        System.out.println(c1);
        System.out.println(c2);
        System.out.println(c3);
        System.out.println(c4);
        System.out.println(c5);
        System.out.println(c6);
        System.out.println(c7);
        System.out.println(c8);
        System.out.println(c9);

        
        //只有元素类型与维度一样，就是同一个Class
        int[] a = new int[10];
        int[] b = new int[100];
        System.out.println(a.getClass().hashCode());
        System.out.println(b.getClass().hashCode());

    }
