求一道简单的java程序

java作业求助!!!!!!!!编一个

import java。io。BufferedReader; import java。io。InputStreamReader; import java。io。IOException; public class Average{ public static void main(String[] args) throws IOException{ while(true){ System。 out。println("please input numbers, put space to split them"); String input = getSNumbers(); int number...全部

  import java。io。BufferedReader; import java。io。InputStreamReader; import java。io。IOException; public class Average{ public static void main(String[] args) throws IOException{ while(true){ System。
  out。println("please input numbers, put space to split them"); String input = getSNumbers(); int numbers[] = new int[0]; try{ numbers = getNumbers(input); }catch(NumberFormatException e){ System。
  out。println("please input positive numbers"); continue; }catch(NotPositiveException e){ System。
  out。println(e。getMessage()); continue; } int total = 0; for(int i=0; i  length; i++){ total += numbers[i]; } try{ int result = total/numbers。length; System。
  out。println(result); }catch(ArithmeticException e){ System。out。println("don't input nothing"); } } } public static int[] getNumbers(String numbers){ String []sNumbers = numbers。
  split(" "); if(sNumbers。length==1&&sNumbers[0]。equals("")) return new int[0]; int[] iNumbers = new int[sNumbers。
  length]; for(int i=0; i  in)); String input = reader。
  readLine(); return input; } } class NotPositiveException extends RuntimeException{ public NotPositiveException(String s){ super(s); } }。收起
