使用字符串初始化我的类的对象

public class MyClass {
    private String name;

    public MyClass(String name) {
        this.name = name;
    }

    public void printName() {
        System.out.println("Name: " + name);
    }
}

public class Main {
    public static void main(String[] args) {
        String className = "MyClass";
        String name = "John";

        try {
            Class<?> clazz = Class.forName(className);
            Object obj = clazz.getDeclaredConstructor(String.class).newInstance(name);
            MyClass myObj = (MyClass) obj;
            myObj.printName();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
