java - How can I use HashMap values to form a String? -

-

i have following code maps specific string characters letters:

 string = "94466602777330999666887770223377778077778 883 336687777";     string[] tokens = a.split("(?<=(.))(?!\\1)");     map<string, string> hmap = new hashmap<string, string>();      hmap.put("2", "a");     hmap.put("22", "b");     hmap.put("222", "c");     hmap.put("3", "d");     hmap.put("33", "e");     hmap.put("333", "f");     hmap.put("4", "g");     hmap.put("44", "h");     hmap.put("444", "i");     hmap.put("5", "j");     hmap.put("55", "k");     hmap.put("555", "l");     hmap.put("6", "m");     hmap.put("66", "n");     hmap.put("666", "o");     hmap.put("7", "p");     hmap.put("77", "q");     hmap.put("777", "r");     hmap.put("7777", "s");     hmap.put("8", "t");     hmap.put("88", "u");     hmap.put("888", "v");     hmap.put("9", "w");     hmap.put("99", "x");     hmap.put("999", "y");     hmap.put("9999", "z");     hmap.put("1", ".");     hmap.put("0", " ");

after doing hashmap, want return string coverts previous string "94466602777330999666887770223377778077778 883 336687777" "who best students"

you can use stringbuilder class form string.

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...
