java - 输入0时如何结束循环？

Question

我正在编写一个程序，用户将不断输入数字，直到使用循环输入 0。然后它将显示输入的最大数字、输入的最小数字以及所有数字的平均值。这就是我必须开始的:

import javax.swing.JOptionPane;                                                    

public class MaxMinAvg
{
   public static void main(String args[])
   {
        String inString = " ";
        int count = 0;


        inString = JOptionPane.showInputDialog("Enter a String");

                                                                                //perform until the end of file
        while(inString.length() != 0)
        {
            count++;
            System.out.println("record " + count + " is " + inString);

                                                                             // second read
            inString = JOptionPane.showInputDialog("Enter a String");

        }                                                                   // end while loop

        System.out.println("All done");

   }
}

尝试将输入字符串与退出条件进行比较:

import javax.swing.JOptionPane;                                                    

public class MaxMinAvg
{
   public static void main(String args[])
   {
        String inString = " ";
        int count = 0;


        inString = JOptionPane.showInputDialog("Enter a String");

                                                                                //perform until the end of file
        while(inString.length() != 0 && !inString.equal("0"))
        {
            count++;
            System.out.println("record " + count + " is " + inString);

                                                                             // second read
            inString = JOptionPane.showInputDialog("Enter a String");

        }                                                                   // end while loop

        System.out.println("All done");

   }
}
