restrict access to a file from multiple threads

A couple of solutions come to mind:

1. Temporarily rename the file when one thread accesses it and then rename it back to its original name when the thread is done

2. Store the file in a variable if it's not too large and then delete the actual file. When done recreate the file and put the contents back

File f = new File("smallFile.txt");

SomeReader sr = new SomeReader(f);

String fileContents = sr.getContents();

sr.close();

f.delete();

//do other stuff with file

f.createNewFile();

or

File f = new File("smallFile.txt");

f.renameTo("tempName");

//do other stuff with file

f.renameTo("smallFile.txt");

This is a hack way of doing it but, if another Thread tries to access the file it won't be there.

Using "synchronized" methods works best.
