Answer 1

You will have to create the file manually unless it already exists. Creating a new File object should not be confused with creating a file in the filesystem.

To create the file you will have to use the method createFile(); which exists in the class File:

File someFile = new File("path.to.file");
someFile.createFile();

It would also be a good idea to check if the file exists before creating it to avoid overwriting it. this can be done by:

File someFile = new File("path.to.file");
if(!someFile.exists()) {
    someFile.createFile();
}

This will create a new empty file. That means that it's length will be 0. To write to the file you will need a byte stream. For example, using a FileWriter:

File test = new File("SomeFileName.txt");
FileWriter fw = new FileWriter(test);
fw.append("Hello! :D");
fw.close();

Note: Some methods i used in the examples above throw exceptions which you will have to handle.
