Writing to Files : Printwriter Converting Forward Slash to Backslash

Why is Printwriter doing this? 

    File file = new File("/files/KA.txt");
    writer = new PrintWriter(file);
    writer.write("HELLO");

In the above code I keep getting an error that says : 

   java.io.FileNotFoundException: \files\KA.txt (The network path was not found)

Except this was not my specified path? How do I then specify a file to write - usually create a new file and write to this? It also throws errors if KA.txt is not present - I ideally want to create a new file and writer to it.

Thanks

The problem is that the parent /files directory doesn't already exist, so you must create it beforehand, using File.mkdirs.

    File file = new File("/files/KA.txt");
    File parentFile = file.getParentFile();
    parentFile.mkdirs();
    PrintWriter writer = new PrintWriter(file);
    writer.write("HELLO");
    writer.close();

You can simply create a file ,

PrintWriter writer = new PrintWriter("name.txt", "UTF-8");
writer.println("text");

where UTF-8 is the file encoding. and write to the file , remember it overrides if the file exists with the same name
