i taking user input using scanner , want store 2 argument given command line how ever able one. believe hasnextint() returns boolean value if there nextint, when enter non-int value doesnot break loop. i have checked sources online , on stackoverflow before posting questions did not looking for. scanner s = new scanner(system.in); int first = 0; int second = 0; system.out.println("please enter number: "); s.usedelimiter(","); while (s.hasnextint()) { first = s.nextint(); system.out.print("firstargument: " + first + "\n"); second = s.nextint(); system.out.print("secondargument: " + second + "\n"); } the problem code calls s.hasnextint() every odd-numbered input, tries take each even-numbered input without performing check. therefore, requires inputs this: 1,2,3,4,5,6,done 1,2,3,4,done 1,2,done however, inputs result in exception: 1,2,3,4,5,done 1,2,3,done 1,done note non-numeric input ...

is possible assign name every element of array? example in array myarr[5] , can give myarr[0] name "first", myarr[1] "second" , on? , if not, might feasible way achieve similar result? use map : map<string, whatever> yourmap = new hashmap<>(); yourmap.put("first", something); yourmap.put("second", somethingelse); then, elements out: system.out.println(yourmap.get("first")); // prints something.tostring() system.out.println(yourmap.get("second")); // prints somethingelse.tostring() // etc. but if you're going use "first" , "second" keys, you're better off using array. maps useful when it's more convenient access things using arbitrary objects rather simple integers keys.
