Saving a file using JFileChooser
I want to save a file to another directory which user selects from one directory. I know that JFileChooser
can be use to select a file. But instead of using any output streams kind of things is there a开发者_如何学Cny way to move a file from one location to another in Java?
Only and only if they are on the same local disk file system, you can use File#renameTo()
for this.
File sourceFile = createItSomehow();
File targetFile = chooser.getSelectedFile();
boolean renamed = sourceFile.renameTo(targetFile);
if (!renamed) {
// Well, perhaps they are not on the same disk?
}
For all other cases, you're really better off by just streaming it. See also the linked javadoc:
Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem to another, it might not be atomic, and it might not succeed if a file with the destination abstract pathname already exists. The return value should always be checked to make sure that the rename operation was successful.
