With this example we are going to demonstrate how to get the content of a File. We will make use of the org.apache.commons.io.FileUtils class, that provides file manipulation utilities. In short, to get the content of a File you should:
- Create a new File by converting the pathname string of the file into an abstract pathname.
- Use
readFileToString(File file)API method oforg.apache.commons.io.FileUtilsto set the contents of the file in a String, and print the String.
Let’s take a look at the code snippet that follows:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | package com.javacodegeeks.snippets.core;import org.apache.commons.io.FileUtils;import java.io.File;import java.io.IOException;public class GetContent { public static void main(String[] args) { try { // We take a reference to an actual file on disk File file = new File("test.txt"); // We store content of test.txt file to a string String content = FileUtils.readFileToString(file); // We print the string System.out.println("Content : " + content); } catch (IOException e) { e.printStackTrace(); } }} |
Output:
Content : Hello World!!!
