How to Convert OutputStream to InputStream
Sometime we need to convert Output Stream to Input Stream. We can perform the conversion multiple ways. The following two approaches are most popular: 1. ByteArrayOutputStream to ByteArrayInputStream 2. PipedOutputStream to PipedInputStream Complete example code is available in the [ Github ]. Approach 1: ByteArrayOutputStream/ByteArrayInputStream The ByteArrayOutputStream/ByteArrayInputStream is the easiest way to convert OutputStream to InputStream. Code snippet: TextWriter textWriterBins = new TextWriter(); ByteArrayOutputStream bouts = new ByteArrayOutputStream(); textWriterBins.write(bouts); ByteArrayInputStream bins = new ByteArrayInputStream(bouts.toByteArray()); TextReader textReader = new TextReader(bins); textReader.print(); Here, TextWriter is a class which writes some text in the OutputStream and TextReader is a class which reads data from InputStream and print on the console. In the above code snippet, the TextWriter.write method writes the data in the
