I am trying to access a file in remote shared location.
////hostname//data//upload//123//test.txt
File sourceFile=new File("////hostname//data//upload//123//test.txt");
sysout("sourceFile.exists()"+sourceFile.exists())//returning false
If a directory is empty file.exists() is returning true. I am using Java 1.6
I don't understand what is this weird behavior.
First of all to come back to Erwin´s suggestion, this is not the right attempt. The character \ is used in Java as an escape sequence, usually to print out reserved characters. For example will
String s = "The weather is really "nice" today";
result in an error, as " is already reserved for strings. The correct version would be
String s = "The weather is really \"nice\" today";
Coming back to the question, you have to know that when you create a file and test if it exists Java will validate the abstract pathname of the file. That said, if your abstact path is a directory and it exists true will be returned.
Edit:
If you intend to check if an abstract pathname is a directory try the following:
// Check if a file is a directory
if(file.isDirectory()) {
}
// Check if a file contains something
if(file.list().length > 0) {
}
Check this example ,it checks the directory else creates a new one then your new file created.
File f = new File("D:/image_send");
File file = new File("D:/image_send/" + date + ".txt");
try {
if(!f.isDirectory()){
f.mkdirs();
}
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("File created Success");
public static boolean fileTransfer(String src, String des) throws Exception {
if (des == null || des.equals("") || src == null || src.equals("")) {
return false;
}
File fileExisting = new File(src);
File fileNew = new File(des+ fileExisting.getName());
if (fileExisting.exists() && !fileExisting.isDirectory()) {
if (fileExisting.renameTo(fileNew)) {
System.out.println("File is moved successful!");
} else {
System.out.println("File is failed to move!");
}
}
return fileNew.exists();
}
This is the code for file transfer as per your comment ,use src as sourcepath and des as destination path if you get a boolean false,that means path given is wrong.
