Java 中一切数据类型都可以获取类对象

  • 接口
  • 基本类型
  • 数组类型
  • Void 类型
/**     * 哪些概念 有类对象     *     * 类 / 接口 / 基本类型 / Void / 数组 都有类对象     */    @Test    public void testAnythingContainsClass() {           // 类        System.out.println("String.class = " + String.class);        // 接口        System.out.println("Map.class = " + Map.class);        // 基本类型        System.out.println("int.class = " + int.class);        // Void        System.out.println("Void.class = " + Void.class);        // 数组        System.out.println("int[].class = " + int[].class);    }
