Here file.createNewFile() needs a try/catch block or need throws declaration in the method signature to compile where as file.isDirectory() is just fine.I expect file.isDirectory() to behave the same way as file.createNewFile() behaves.Can anyone explain this
Why would it throw an IOException if no I/O takes place? The method can throw an uncheckedSecurityException, which (obviously) is not subject to the same catch-or-declare requirement as the IOException thrown by the createNewFile() method.

file.createNewFile is modifying the file system while file.isDirectory is only checking the status of the file system.
