java系统找不到指定路径,java.io.FileNotFoundException系统找不到指定的路径

I have a timer set to invoke a class that contains pdf generating codes.I have set the file path where it needs to be saved..but it is showing exception as java.io.FileNotFoundException : D:\ (The system cannot find the path specified) .I dont know where is the mistake..

Here is my code..

try {

OutputStream file = new FileOutputStream(new File("D://"));

Document document = new Document();

//PDF generating code..

document.add(list); //In the new page we are going to add list

document.close();

file.close();

System.out.println("Pdf created successfully..");

} catch (Exception e) {

e.printStackTrace();

}

解决方案

You have not provided the file name so you get that exception,use below code

OutputStream file = new FileOutputStream(new File("D://timer.pdf"));
