In the snippet below you’ll learn to open file for reading using Files.newBufferedReader() method in JDK 7. This method returns a java.io.BufferedReader which makes a backward compatibility with the old I/O system in Java. To read a file you’ll need to provide a Path and the Charset to the newBufferedReader() method arguments. package org.kodejava.io; import […]
To open a file for writing in JDK 7 you can use the Files.newBufferedWriter() method. This method takes three arguments. We need to pass the Path, the Charset and a varargs of OpenOption. For example, in the snippet below we pass the path of our log file, we use the StandardCharsets.UTF_8 charset, and we use […]
