java - File.createTempFile check if file exists? -


if use method, , chance there temporary file same name, file overwritten? i'm talking application generate many temporary files, long time.

from javadoc on createtempfile (here) on line labeled 2,

neither method nor of variants return same abstract pathname again in current invocation of virtual machine.

edit

and returns section says

an abstract pathname denoting newly-created empty file

and, further states

creates new empty file in specified directory, using given prefix , suffix strings generate name. if method returns guaranteed that: file denoted returned abstract pathname did not exist before method invoked
