File f = new File(\"C:\\\\Temp\\\\Example.txt\");
f.createNewFile();
On executing, a new file named \"Example.txt\" will be created in the Temp>
Please use File.separator to be independent from the OS:
String home = System.getProperty("user.home");
File f = new File(home + File.separator + "Desktop" + File.separator + "Testing" + File.separator + "Java.txt");
Or use org.apache.commons.io.FilenameUtils.normalize:
File f = new File(FileNameUtils.normalize(home + "/Desktop/Testing/Java.txt"));
Either of them can be used (the second option needs library)
