我用 jQuery 写了这个，但是循环不正确，我看不到我的错误？当用户输入-99时它不会结束？也不计算最高和最低的数字？
import java.util.Scanner;
public class LargestandSmallest
{
public static void main (String [] args)
{
//Create a Scanner object for the keyboard input
Scanner keyboard = new Scanner(System.in);
//Declare local variable
double number;
//Explain what the program does
System.out.println ("This program will ask you to enter in a series of");
System.out.println ("numbers, and then will display the lowest and");
System.out.println ("highest numbers, out of what you enter, until you input");
System.out.println ("the value indicated to end the program.");
//Have the user input a series of numbers and continue processing
//until the user enters -99
System.out.println ("Please enter a number: (or -99 to end the program).");
number = keyboard.nextDouble();
//Display the table headings
System.out.println ("Lowest\tHighest");
System.out.println ("------------------");
//Call the method to caluclate the highest and lowest numbers
calculateLowHigh(number);
}
//Module called calculateTemp
public static void calculateLowHigh(double number)
{
//Declare local calculation variables
double highestNumber = 0;
double lowestNumber = 0;
//Set the parameters for running the loop
while (number != -99)
{
for(number = 0; number < 5; number++)
{
//Calculate the lowest and highest numbers entered
if (number > highestNumber) {
highestNumber = number;
}
if (number < lowestNumber) {
lowestNumber = number;
}
}
}
//Display the results
System.out.println (lowestNumber + "\t\t" + highestNumber);
}
}
