如何检索泛型类的类

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

public class GenericClass<T> {
    public static void main(String[] args) {
        GenericClass<String> genericClass = new GenericClass<>();
        Class<?> genericType = getGenericType(genericClass);
        System.out.println("Generic type: " + genericType.getName());
    }

    public static Class<?> getGenericType(GenericClass<?> genericClass) {
        Type type = genericClass.getClass().getGenericSuperclass();
        if (type instanceof ParameterizedType) {
            ParameterizedType parameterizedType = (ParameterizedType) type;
            Type[] typeArguments = parameterizedType.getActualTypeArguments();
            if (typeArguments.length > 0) {
                return (Class<?>) typeArguments[0];
            }
        }
        throw new IllegalArgumentException("Unable to retrieve generic type.");
    }
}

Generic type: java.lang.String
