- Example: Reader Using FileReader
In order to use the functionality of Reader, we can use its subclasses. Some of them are: 1. BufferedReader 2. InputStreamReader 3. FileReader 4. StringReader We will learn about all these subclasses in the next tutorial.
In order to create a Reader, we must import the java.io.Readerpackage first. Once we import the package, here is how we can create the reader. Here, we have created a reader using the FileReader class. It is because Reader is an abstract class. Hence we cannot create an object of Reader. Note: We can also create readers from other subclasses of Rea...
The Readerclass provides different methods that are implemented by its subclasses. Here are some of the commonly used methods: 1. ready()- checks if the reader is ready to be read 2. read(char array) - reads the characters from the stream and stores in the specified array 3. read(char array, int start, int length) - reads the number of characters e...
Here is how we can implement Reader using the FileReaderclass. Suppose we have a file named input.txtwith the following content. Let's try to read this file using FileReader (a subclass of Reader). Output In the above example, we have created a reader using the FileReader class. The reader is linked with the file input.txt. To read data from the in...

We have provided EasyReader and EasyWriter classes to supplement Java's stream I/O classes. EasyReader lets you read numbers, characters, words, and strings from the console and from a text file. EasyWriter lets you write these data elements into a text file (or append data to an existing file).
