Arraylist writing to a file with new Lines in it

[Santosh Kumar Nayak]

Using the code below :-



import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.*;


public class WriteFile {
public static void main(String [] args) {
ArrayList<String> al = new ArrayList<String>();
al.add("msjksl");
al.add("rakesh");
al.add("mnopq");
al.add("kmjdc");
al.add("ramesh");
al.add("rajesh");
al.add("hello");


FileWriter fw= null;
File file =null;
try {
file=new File("C:/Users/nayasant/Desktop/WriteFile.txt");
if(!file.exists()) {
file.createNewFile();
}
fw = new FileWriter(file);

Iterator<String> iterator = al.iterator();
while (iterator.hasNext()){
fw.write(iterator.next());
}
fw.close();
System.out.println("File written Succesfully");
} catch (IOException e) {
e.printStackTrace();
}
}
}


I want to achive as the WriteFile.txt should have entries with new lines:

Output should be :-
msjksl
rakesh
mnopq
kmjdc
ramesh
rajesh
hello

The easiest way to accomplish it is to write the newlines too. Or you can use a PrintWriter instead.

Have you never tried a Formatter for a text file? The one problem I have had with Formatters is that I have never managed to get them to append to a file, which you can do quite simply with a Writer.

try (Formatter f = new Formatter(new File("path\\to\\my\\file")))
{
   for (String s : myList)
   {
      f.format("%s%n", s);
   }
}
finally
{
   // empty
}
