Cracking the coding interview — 189 questions and answers; data structure and algorithms analysis for job interviews; 130 java interview questions of last 5 years; p.s. — if you need some free resources to learn java, you can check out this list of free java courses to start your preparation. p. s. s. In this tutorial, we show you how to read from and write to text (or character) files using classes available in the java.io package. first, let’s look at the different classes that are capable of reading and writing character streams. 1. reader, inputstreamreader, filereader and bufferedreader. reader is the abstract class for reading. This is important for resource management and avoids memory leaks. bw.write("hello, world!\n");and bw.write("this is a line written to the file."); these lines write text to the file using the write()method of the bufferedwriter. each write()call adds text to the file. this \nis used to insert a newline character.

Start by coding answers to these questions. force yourself to pretend you’re in an interview setting by solving them 10–15 minutes. before you write a single line of code, organize your thoughts and figure out the solution. then start coding. do the same in the interview. The main difference between these two packages is that the read() and write() methods of java io are blocking calls. by this we mean that the thread calling one of these methods will be blocked until the data has been read or written to the file. on the other hand, in the case of nio, the methods are non blocking.
