Java StorageResource类型的错误消息

Java StorageResource类型的错误消息,java,Java,我已经试着解决这个问题一段时间了,但是没有用。当我运行代码时,我收到以下错误消息:不兼容的类型:edu.duke.StorageResource无法转换为java.lang.String,位于String geneList=FMG.storeAll(dna)行。这是否意味着我试图使edu.duke对象与java.lang.String类型的对象一起工作?我们将如何解决这个问题 以下是我目前的代码: package coursera_java_duke; import java.io.*; imp

我找到了你的帖子,因为我还在杜克大学使用那些edu.Duke库学习类似的课程

当我收到错误消息时,是因为我使用了错误的方法来访问它


尝试FMD.data()获取所有基因字符串的iterable。

您没有调用代码的主方法,因此我们甚至不知道正在运行什么。我们也不知道输入。我在理解这一点时有点困惑。1:不确定edu包是什么,但是没有这些人就不能测试你的代码。2:代码看起来根本不起作用。这两个可能只是我,但也没有地方,你会打印输出,你似乎期待,fx“3:atgtaa”。
