javascript - How to get index of a key value pair -

- 

    var myobj={         age: null,         anothercolumn: null,         casenum: null,         casecount: null,         casecountfgfg: null,         city: null,         country: null,         county: null    }

i have change key name @ 3rd position. information have new key name , position .

something like

myobj[2] = 'new value'

please suggest

be really careful! before es2015 order of property keys not specified. can change , different browser browser.

in es2015 order specified order of creation.

so can not want.

the possible way create new object , apply keys in order want. can recommend not depend on order of object keys!

filehandler - java open files not cleaned, even when the process is killed -

there java program read files folder, processing , write output files in folder. ran 4 hours , produced few files failed after throwing following error: "too many files" then modified program close (bufferreader , bufferwriter) , started process again. time process failed after starting throwing following error: java.io.filenotfoundexception: <file> (too many open files) then tried running lsof , searched process having no of open files. realized networkmanager. not sure whether should kill process or not. restarted machine. after when ran java program, still got same error. in worst case might possible code still having leaks in terms of not closing everything, still failing after starting process. have feeling lying in system previous run. if start same process in other machine, runs hours before failing. you cannot retain resource between runs of program, if wanted to. leave system without enough resources in theory, though unlikely, restarting...
