java - How to read a line of numbers and display the sum? -

i'm working on programme read whole line of numbers , display sum. must written in java , must simple possible. nil much harder arrays or ever needed create work.

this illustration of want:

please come in numbers space in between each. 12 34 7 93 4 sum of numbers: 150

i have had number of attempts , have got @ moment.

public static void main(string[] args) { scanner kb = new scanner(system.in); int numbers; int total; system.out.println("please come in numbers space between each"); numbers = kb.nextint(); for(int i=args.length; i<numbers; i++) { system.out.println("the sum " + numbers); } }

scanner#nextint reads single int input stream. instead, want read bunch of numbers , start working on them.

i can think on 2 solutions this:

read whole line (using scanner#nextline), split blank space (" ") (using string#split), convert each string int , calculate sum (using integer#parseint).

int total = 0; system.out.println("please come in numbers space between each"); string linewithnumbers = kb.nexline(); string[] numbers = linewithnumbers.split(" "); (string number : numbers) { total += integer.parseint(number); }

read whole line (using scanner#nextline), utilize scanner read integers stored in string , calculate sum.

int total = 0; system.out.println("please come in numbers space between each"); string linewithnumbers = kb.nexline(); scanner linescanner = new scanner(linewithnumbers); while (linescanner.hasnext()) { total += linescanner.nextint(); }
