java异常:error while reading input message; nested exception is java.io.IOException: Stream closed 今天在跑自动化测试案例的时候,因为案例的变量是字符串string类型的,结果自己没有把变量用引号包裹起来,故报异常,记录下来。以备后需 案例格式:
1. Java I/O (Input / Output) for files 1.1. Overview Java provides a standard way of reading from and writing to files. Traditionally thejava.iopackage was used, but in modern Java applications you use thejava.nio.fileAPI. Java will read all input as a stream of bytes. TheInputStream...
BufferedReaderis supported since Java 1.1. We may see its usage in legacy Java applications. To read console input, we shall wrap theSystem.in(standard input stream) in anInputStreamReaderwhich again wrapped in aBufferedReaderclass. BufferedReaderreads text from the console, buffering characters so...

To read a properties file in Java, you can use the Properties class from the java.util package.

. To do so, we call theZipFile.entries()method. This returns us anEnumerationofZipEntryobjects which we can then query for their name or use as a reference to get an input stream from theZipFile. For example, the following pattern will read from just the entries whose name ends in....
