public static void main(String[] args) {
try {
//Using FileUtils
usingFileUtils();
} catch(IOException e) {
System.out.println(e.getMessage());
}
}
public static void usingFileUtils() throws IOException {
//get the file object
File file = FileUtils.getFile("input.txt");

//get the temp directory
File tmpDir = FileUtils.getTempDirectory();

System.out.println(tmpDir.getName());

//copy file to temp directory
FileUtils.copyFileToDirectory(file, tmpDir);
//create a new file
File newTempFile = FileUtils.getFile(tmpDir, file.getName());

//get the content
String data = FileUtils.readFileToString(newTempFile, Charset.defaultCharset());
