Here's the edited java code -

//This program calculates a running total. Here is the problem definition
//Data Express, an Internet Service Provider, has requested that you develop a program to allow
//sales representatives to calculate a running total of their sales based on a number of days.
//The program prompts the salesperson “How many days do you have sales figures? “.
//The number of days must be between 1 – 4 days (keep asking the user until a valid input is provided).
//The program then prompts the user to enter a sales value for each day and calculates the total sales amount.
//Name: put your name here!! //class: CSCI 1250-XXX //Exam: Quiz 4- Spring 2019
//Date:
//********************************************** Total points out of ??/100 ************************************
// //1- Add the missing import statement (5 points)

import javax.swing.JOptionPane;
public class Quiz4 {
public static void main(String[] args) {
int days;// The number of days
double sales; // A day's sales figure
double totalSales;// Accumulator
boolean flag = false;
//2- Declare an input variable to hold the user's input (5 points)
String input;
//3- Get the number of days from the user by using JOptionPane class. (5 points)
input = JOptionPane.showInputDialog("How many days do you have sales figures?");
//4- parse the input and assign the result to days (5 points)
days = Integer.parseInt(input); //to convert string to integer value
//5- create a while loop that limits the number of days between 1 - 4 days (10 points)
//You should keep asking for a valid value between 1 - 4 days
while(days<1 || days>4){ //this loop will keep repeating until days is between 1 and 4
input = JOptionPane.showInputDialog("Invalid input, input the number of days between 1 and 4");
days = Integer.parseInt(input); //to convert string to integer value
}
//6- Set the accumulator to 0.0 (5 points)
totalSales = 0.0;   
//7- Get the sales figures and calculate a running total using a for loop.
for (int count = 1; count <= days; count++) {
//8- Ask the user to "Enter the sales amount for day (count)": (5 points)
input = JOptionPane.showInputDialog("Enter the sales amount for day " + count);
//9- parse input and assign it to sales (5 points) totalSales =
sales = Double.parseDouble(input); //to convert string to double value
//10- Add sales to totalSales. (5 points)
totalSales = totalSales + sales;
//11 If sales (NOT totalSales) at any of the days exceeds $10,000 set the flag to true (10 points)
if(sales>10000){
flag = true;
}
}
//12-Display the total sales using a showMessageDialog with a $ (10 points)
JOptionPane.showMessageDialog(null,"total sales = $"+totalSales);
if(flag==true){ //13- if the sales for any of the days exceeds $10,000.00 (20 points)
// Congratulate the user by displaying "You are outstanding!!!"
JOptionPane.showMessageDialog(null,"You are outstanding!!!");
}
//14- Terminate the JDK by indicating that the program has completed successfully (5 points)
System.exit(0);
}
//end main(String[])
