If, for an example, our file contains a long list that we want to sort, we'll have to read it into an adequate data structure, perform operations, and then persist it once again - in this case anArrayList. This can be achieved with several different approaches: Files.readAllLines() File...
Read text file with InputStreamReader InputStreamReaderis a bridge from byte streams to character streams. It reads bytes and decodes them into characters using a specified charset. Main.java import java.io.BufferedReader; import java.io.FileInputStream; ...
Finally, we print the content of the file. This approach simplifies file reading in Java 7 and is concise and efficient for reading text files into strings. 3. How to read String from file using Scanner As I said before, the Java programming language offers various methods to read data...
