线程“主”异常java.util.IllegalFormatConversionException：g！= java.lang.String

Question

我对Java有点新，并希望如果有人能帮助我。我正在使用文本编辑器在虚拟机Ubuntu上编写此代码。如果您想引用该文件，RAM错误就在这里。 http://users.cis.fiu.edu/~crahn/CGS3767/RAMerrors。该错误位于System.out.printf中的public static readingLine中。如果有人能帮助我识别错误，我将不胜感激。谢谢！

Answer 1

你想要一个%s转换为您String说法recordingLine，不%g

Answer 2

recordingLine预计将浮动，但发现是字符串。
