java - Possible memory leak with StringBuilder? -


i using stringbuilder create file object, using see if directory file located inside of exists:

stringbuilder sbfile = new stringbuilder(); sbfile.append("/home/logs/");  file ofile = new file(sbfile.tostring());  if(!ofile.exists())     ofile.mkdir();  sbfile.append("mylogfile.log");  ofile = new file(sbfile.tostring());

but worried reusing same ofile reference on 2 different "versions" of string builder (/home/logs/ vs /home/logs/mylogfile.log) create memory leak. if so, how should write differently?

there no memory leak. instance of file created first time, garbage-collected jvm when no longer used.

the other thing don't need use stringbuilder. file class has constructor takes parent , filename. example this:

file parent = new file("/home/logs/"); if(!parent.exists())     parent.mkdir();  file file = new file(parent, "mylogfile.log"); // todo: file...

also, may interested in how garbage collection works in java.
