Get content of a File

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 of org.apache.commons.io.FileUtils to set the contents of the file in a String, and print the String.

Let’s take a look at the code snippet that follows:

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!!!
