Introduction

In this page you can find the example usage for org.apache.commons.io FileUtils openInputStream.

Prototype

public static FileInputStream openInputStream(File file) throws IOException

Source Link

Document

Opens a FileInputStream for the specified file, providing better error messages than simply calling new FileInputStream(file).

Usage
