编写程序，读入未指定个数的整数，判断的正数有多少个，读入的负数有多少个，然后计算这些输入值的总和及其平均值（不对0计数）。当输入为0时，表明程序结束。将平均值以浮点数显示。
import java.util.Scanner;public class Question_Five_1 {public static void main(String[] args) {// TODO Auto-generated method stubScanner input=new Scanner(System.in);int positivesnum=0,negativesnum=0,getdata,count=0;double total=0,average;System.out.println("Enter an integer,the input ends if it is 0：");getdata=input.nextInt();while(getdata!=0){if(getdata>0)positivesnum+=1;elsenegativesnum+=1;count++;total+=getdata;getdata=input.nextInt();}System.out.println("The number of positives is "+positivesnum);System.out.println("The number of negatives is "+negativesnum);System.out.println("The total is "+total);System.out.println("The average is "+total/count);}}
