java - 如果我想要一个 0 来结束程序，我应该把程序放在哪里？

Question

如果我想结束程序，如果有人在输入任何其他数字之前输入“0”，我会使用(以及我将把它们放在哪里？)

while (number == 0){
System.out.println("No numbers are entered except 0");
System.exit(0);}" 

或者我会使用

if (number == 0){
System.out.println("No numbers are entered except 0");
System.exit(0);}"

我的程序如下:

import java.util.*;
public class Count2{
public static void main(String[] args){

Scanner input = new Scanner(System.in);
int number, maxNum=0, count=0;

System.out.print("Enter a number (0 ends the input): ");
  do {
   number = input.nextInt();
   if (number > maxNum){
   count = 0;
   maxNum = number;
   }
   if (number == maxNum){
    count++;
   }

 }
while (number !=0);

System.out.println("The maximum numver is " +maxNum);
System.out.println("The count for the max number is " + count);
}

}}

我尝试添加代码以在“do”之前输入整数以及退出代码，但是当我这样做时，我的计数最后困惑了

我只想进行一个 while true 循环。请注意，第一个实例中的 count 应设置为 1

int number=0, maxNum=0, count=0;
while (true) {

   number = input.nextInt();
   if (number == 0) {
     break;
   }

   if (number > maxNum){
      count = 1;   // if greater than existing then set to one
      maxNum = number;
   }
   else if (number == maxNum){
      count++;
   }
}

// print
if (count == 0){   // if a non-zero was entered then `count` will be `1`
    System.out.println("No numbers are entered except 0");
}
