Question

我对java有点新，并希望有人能帮助我。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中的公共静态readingLine中。如果有人能帮助我识别错误，我将非常感激。谢谢！

Answer 1

您希望对%s参数String进行recordingLine转换，而不是%g

Answer 2

recordLine预计会浮动，但发现是字符串。

线程“main”中的异常java.util.IllegalFormatConversionException：g！= java.lang.String
