Question

所以我試圖使 （EX）輸入一些值：1 -2 -3 2 5 正數的數量是5數負數是-3 總數是3平均數是。 6 我想這樣做，但是當我運行它時， 它不起作用 什麼部分是錯誤？

import java.util.*; 


public class Welcome { 

public static void main(String [] args){ 

    Scanner input = new Scanner(System.in); 
System.out.print("Enter an int value, the program exits if the input is 0: "); 
    int num = input.nextInt(); 
    int countpos = 0; 
    int countneg = 0; 
    int totalnum = 0; 
    int total = 0; 
    double avg = 0.0; 

    while(num != 0){ 

     if(num < 0) 
      countpos++; 
     else 
      countneg++; 

     total = total + num; 
     totalnum++; 
    } 

    System.out.print("num of pos is: " + countpos); 
    System.out.print("num of neg is: " + countneg); 
    System.out.print("total is: " + total); 
    System.out.print("the avg is: " + total/totalnum); 

} 

}

你要做的num = input.nextInt();在環太

while(num != 0){ 

     if(num < 0) 
      countpos++; 
     else 
      countneg++; 

     total = total + num; 
     totalnum++; 

     num = input.nextInt(); 
    }
