How to get an already existing file (on my computer) in my method and convert it to InputStream? : <p>I've a generated file in D:/EXPORT_BASE/Export_report. What I need to do is use the filePath string to fetch this file from my local, and then convert this to InputStream.</p>

<p><code>String filePath = D:/EXPORT_BASE/Export_report/1557834965979_report.txt</code></p>

<p>I need to use the String to get the file and write it to InputStream.</p>
