I have a slight delema with learning FileWriter... The ultimate goal is writing a program that will "spawn" a .bat file that will be executed by the batch code that launched the .jar. The problem is, I have no clue how to make sure that every FileWriter.write(); will print on a new line... Any ideas??
To create new lines, simply append a newline character to the end of the string:
FileWriter writer = ...
writer.write("The line\n");
Also, the PrintWriter
class provides methods which automatically append newline characters for you ( edit: it will also automatically use the correct newline string for your OS):
PrintWriter writer = ...
writer.println("The line");
Use a BufferedWriter and use writer.newLine() after every write-operation that represents one line.
Or, use a PrintWriter and writer.println().
If you are using BufferedWriter
then you can use an inbuilt method :
BufferedWriter writer = Files.newBufferedWriter(output, charset);
writer.newLine();
