在java中可以在运行时构建这样的对象吗？

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

public class ReflectExample {
    public static void main(String[] args) {
        try {
            // 获取类的Class对象
            Class<?> clazz = MyClass.class;

            // 使用默认构造函数创建对象
            Object obj1 = clazz.newInstance();

            // 获取带参数的构造函数
            Constructor<?> constructor = clazz.getConstructor(String.class, int.class);

            // 使用构造函数创建对象
            Object obj2 = constructor.newInstance("example", 123);

            System.out.println(obj1);
            System.out.println(obj2);
        } catch (InstantiationException | IllegalAccessException | NoSuchMethodException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }
}

class MyClass {
    private String name;
    private int value;

    public MyClass() {
        this.name = "default";
        this.value = 0;
    }

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

    @Override
    public String toString() {
        return "MyClass{" +
                "name='" + name + '\'' +
                ", value=" + value +
                '}';
    }
}
