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

-
i have bunch of bytes written line line file each line can have varying number of bytes , need read them line line wondering how in efficient way using nio or apache commons io? trying see if there way api can take care of allocation , deallocation of buffers since dont know length of bytes in each line. can read string , .getbytes().length() sounds bit awkward. if file consists of lines, can read millions of lines second bufferedreader.readline(). don't need else. in case nio doesn't support reading lines in way shape or form.

in highcharts show percentage along pie_charts , legend can customized this: legend: {labelformat: '{name} : {y} ({percentage}%)'} but in chartkicks can't find how this? if @ documentation specified on chartkick gem homepage, says: you can pass options directly charting library with: <%= line_chart data, library: {backgroundcolor: "#eee"} %> so in scenario, should try like: <%= pie_chart data, library: {legend: {labelformat: '{name} : {y} ({percentage}%)'}} %>
