It takes a reader object that so we pass a new FileReader to its constructor. The BufferedReader class reads text from a character-based input stream. Using the BufferedReader Class to Open a File in Java Duis velit mi, dapibus vel scelerisque vitae, sagittis vitae purus. Etiam suscipit non sapien vitae condimentum. Integer hendrerit orci eu erat pretium hendrerit.

In a leo vestibulum, commodo erat eget, cursus purus. Suspendisse est odio, euismod vel porta ac, dapibus at lorem. Vestibulum sed ligula ut ligula bibendum pharetra. Integer eget quam malesuada, molestie nibh id, vestibulum libero. Lorem ipsum dolor sit amet, consectetur adipiscing elit. import java.io.File įile f = new File('/Users/john/Desktop/demo.txt') įileInputStream fIS = new FileInputStream(f) In the while loop, we read the characters of the stream until the read() method returns -1. We read the contents of the file and writes it to the terminal. We create a FileInputStream fIS to read from the file object, f in our code. The FileReader class is recommended for reading files, though.

Hence it can be used to open and read files. It can also be used to read streams of characters as it obtains input bytes from files. The FileInputStream class is used to read byte-oriented data such as audio, image data, video, etc. import java.awt.* įile file = new File('/Users/john/Desktop/demo.txt') We call desktop.open() to open the file in the default text editor. We use the method exists() on the file object to check if the file exists. We get the Desktop instance desktop of the current browser context. It returns immediately if the Desktop.isDesktopSupported() returns false if the system does not support the Desktop.

We create a new File class object passing the path to the text file as an argument. The Desktop class has the open() method that launches the registered application to open a file which it takes as an argument. It throws FileNotFoundException if there is no registered application or it fails to be launched. Its implementation is platform-dependent hence, it is necessary to check whether the operating system supports Desktop or not. The Java AWT package has a Java Desktop class used to launch registered applications on the native desktop to handle a file or URI. Using the Desktop Class to Open a File in Java We will discuss a few of them here in this article. There are many ways to open a file in Java.
