Set content to a file

In this example we shall show you how to set the content to a File. We will make use of the class, that provides file manipulation utilities. To set the content to a File one should perform the following steps:

  • Create a new File by converting the pathname string of the file into an abstract pathname.
  • Create a String to be written to the file.
  • Use writeStringToFile(File file, String data) API method of, that writes the String to the file creating the file if it does not exist using the default encoding for the VM.
  • Use readFileToString(File file) API method of to read the contents of the file,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;


public class SetContent {
	public static void main(String[] args) {
		try {
			// We take a reference to an actual file on disk
			File file = new File("test.txt");
			// We set the string to be written to the file
			String data = "Javacodegeeks!!!";

			// We write to the file with writeStringToFile Method
			FileUtils.writeStringToFile(file, data);
			// We test the result
			String content = FileUtils.readFileToString(file);	 
			System.out.println("Content : " + content);
		} catch (IOException e) {
