java输入流问题

我有好几个方法每个里面都用到了sc.write(s);这个写入的方法,我在主函数里调用这些方法,结果报出:
Exception in thread "main" org.apache.poi.openxml4j.exceptions.OpenXML4JRuntimeException: Fail to save: an error occurs while saving the package : The part /docProps/app.xml fail to be saved in the stream with marshaller org.apache.poi.openxml4j.opc.internal.marshallers.DefaultMarshaller@4fbf1942

我只执行一个方法就没事,我该怎么办啊?

  • 我说我不帅他们就打我,还说我虚伪

    `at test.UseProcess.UseProcessSum(UseProcess.java:198)
    at test.TestMain.main(TestMain.java:42)`
    看看这两行代码有没有问题,最好把代码贴出来看看。
