There are three ways to create instances by reflection (2022.6.6-6.12)

Reflect three ways to create class instances :

Primitive class : TestDemo

1. Use the bytecode full path of the native class directly :
Class<TestDemo> class = Class.forName("com.xxx.TestDemo");

2. Use the static class attribute of the native class to create : Notice the exception thrown
Class<TestDemo> class = TestDemo.class;

3. Create an instance object of the native class , And used this object to get this class :
TestDemo td = new TestDemo();
Class<TestDemo> class = td.getClass();

adopt class Object to create class instances :

TestDemo testDemo = class.newInstance();
