Class< > superClass = null;
try {
personClass = Class.forName("org.zhang.test.Person");
superClass = personClass.getSuperclass();
System.out.println(superClass.getName());
} catch (ClassNotFoundException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
}
}
结果：
java.lang.Object
实例7：获取修饰符、方法、返回类型等
