59,314,030 | How can I store user input in arrays and then print them out? | <p>I am a beginner programmer and I am making a little application for practice.</p>
<p>You enter your budget, then you add an expense(name, amount)
and it subtracts and tells you your current budget.</p>
<p>I want to make it so you can see all of your expenses after each execution.</p>
<p>I have tried to make for loops that store the names of the expenses and then print them.
But I am doing something wrong :/.</p>
<p>Sorry for my bad English, I am from Croatia!</p>
<p>Here is some beginner ugly code.</p>
<pre><code> int length = 0;
String[] listOfNames = new String[length];
boolean active = true;
int budget = 0;
Scanner input = new Scanner(System.in); //user input
System.out.println("Enter current budget in HRK");
int enteredAmount = input.nextInt(); //user input for budget
budget = enteredAmount;
while(active)
{
System.out.println("Current budget is " + budget + " HRK");
System.out.println("Enter expense name and amount");
System.out.println("Name: ");
String name = input.next(); //name of expense
for(int i=0; i<listOfNames.length;i++){ //adds entered expense names to array
listOfNames[i] = name;
length++;
}
System.out.println("Amount: ");
int enteredAmount1 = input.nextInt();
budget -= enteredAmount1; // subtracts the budget from the users input
System.out.println("Expense: " + name + ", Amount: " + enteredAmount1); // prints final result
for(int j=0; j<listOfNames.length; j++) // prints stored strings in array
{
System.out.println(listOfNames[j]);

<p>When calling a new Menu in my client, it allows me to store items (as if it was an arraylist), it also allows me to implement the command design pattern and print all of my items out. However, I was adding a Tab class which used information from my Menu object, but it doesn't let me use .get() to retrieve information from my arraylist.</p>
<pre><code>import java.util.*;
public class testClient {
public static void main(String[] args) {
Menu menu = new Menu();
Tab tab;
System.out.println("MENU:");
menu.addItemToMenu("lobster", "#1234" , 25.99);
menu.addItemToMenu("chicken", "#5687" , 20.99);
menu.addItemToMenu("steak", "#4567" , 21.99);
DisplayMenu dispMenu = new DisplayMenu(menu);
SubmitButton onPressed = new SubmitButton(dispMenu);
onPressed.submit();
System.out.print("\n");
System.out.println("ORDERS:");
Order order = new Order();
order.addNewOrder("#1234");
order.addNewOrder("#5678");
SubmitOrder submitOrder = new SubmitOrder(order);
SubmitButton onSubmitPressed = new SubmitButton(submitOrder);
onSubmitPressed.submit();
tab.constructTab(newMenu.get(0).getItemName(), order.get(0).getOrderItemNumber(), newMenu.get(0).getItemCost());
}
}
</code></pre>
<p>The line tab.constructTab(....), returns the following error:</p>
<pre><code>testClient.java:31: error: cannot find symbol
tab.constructTab(menu.get(0).getItemName(), order.get(0).getOrderItemNumber(), menu.get(0).getItemCost());

</code></pre>
<p>it says that menu is of type Menu when it should be an arraylist? I don't understand why it allows me to add items then.</p>
<p>Please let me know if you need any additional code.</p>

59,341,124 | One last function before application closes? (Python) | Ok so look, I'm getting desperate since I've already been all over the internet trying to find the answer to this question. so sorry if this has been answered somewhere else, I couldn't find it just give me the link.
So basically I have a python file that is constantly using the ```f.write()``` function to write to another text file, however, the script doesn't stop writing to the file until it's closed manually.
This is all fine and dandy, except for the fact that any delay greater than 0.01 doesn't seem to save my edits to the text file, so doing a little bit of investigation, an easy fix is the ```f.close()``` function.
So what I need is a line of code that can detect once the script has been stopped, and put out one last function before being fully closed. | <python> | 2019-12-15 03:57:26 | LQ_EDIT |

import (
"bufio"
"fmt"
"log"
"os"
)
func main() {
file, err := os.Open("/path/to/file.txt")
if err != nil {
log.Fatal(err)

defer file.Close()
lines := make(chan string)
for i := 0; i < 100; i++ {
// start 100 workers to process input lines.
// the workers terminate once 'lines' is closed.
go worker(lines)
}
scanner := bufio.NewScanner(file)
go func() {
defer close(lines)
for scanner.Scan() {
lines <- scanner.Text()

59,353,078 | Why should a python variable of type list should be defined first before assigning a value? | <p><code>x = 2</code></p>
<p>creates an integer variable. </p>
<p><code>y.append(3)</code></p>
<p>gives an error message (name 'y' is not defined). </p>
<p>In the first one a variable <code>x</code> can be assigned a value without first defining it, why can't we do the same thing with the lists (you have to first define it using <code>l = []</code>). Is this the result of a fundamental design choice in the Python language?
Thanks.</p>

59,388,443 | Converting A Non-Vuetify Element To Vuetify | <p>I am using a 3rd party payment processor that inserts text inputs into my form. The rest of my form is styled with vuetify (v-text-field). How can I convert a non-vuetify element into vuetify's version of it if the element gets added programmatically (i.e. I don't have control of the text field getting added since this is a 3rd party script)</p>
