java - How to wait in the same thread while file is being written to, to finish, so we can use it -

i have file open , write situation crashes eofexception once in 20-30 times, because file unavailable because other process writing it.

can catch exception, somehow wait file write operation synchronously end, can recurse method?

file productjson = getfilestreampath("product" + "_" + getid() + ".json"); if (!productjson.exists()) {     productjson = getfilestreampath("product" + ".json"); }  inputstream jsonstringsfileinputstream; try {     jsonstringsfileinputstream = new fileinputstream(productjson);      hashmap<string, map> = new jsontoproductparser().convertthistothat(jsonstringsfileinputstream);  } catch (filenotfoundexception e) {     e.printstacktrace(); } 

you can check file write access before opening it.this done canwrite() method.
