如何在运行时知道泛型类型的类型参数时进行编程？

import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;

public class GenericClass<T> {
    public void printGenericType() {
        Type genericType = getClass().getGenericSuperclass();
        if (genericType instanceof ParameterizedType) {
            ParameterizedType parameterizedType = (ParameterizedType) genericType;
            Type[] typeArguments = parameterizedType.getActualTypeArguments();
            if (typeArguments.length > 0) {
                Type typeArgument = typeArguments[0];
                System.out.println("Generic type argument: " + typeArgument);
            }
        }
    }
}

public class Main {
    public static void main(String[] args) {
        GenericClass<String> genericClass = new GenericClass<>();
        genericClass.printGenericType();
    }
}
