I can't set a string in a TextView in an Android app (using Java)

I'm building a simple calculator Android app in Java that will receive 2 numbers as inputs and when the user presses one of the 4 action buttons (+, -, *, /) the exercise and it's solution will appear in the bottom of the screen inside a TextView in this format:
{num1} {action} {num2} = {solution}
I tried to declare a string and form the exercise's string in it and in the end I used "setText" to change the TextView but instead of showing the full exercise when I run the app it shows something like "androidx.appcompat.widget.AppCom".
Here is an example for the string I form when the user clicks on the + button:
exerciseStr = etNum1.toString() + " + " + etNum2.toString() + " = " + String.valueOf(Integer.valueOf(etNum1.getText().toString())+Integer.valueOf(etNum2.getText() + ""));
Does anybody know what the issue may be?

You should call getText() befor calling toString():
exerciseStr = etNum1.getText().toString() + " + " + etNum2.getText().toString() + " = " + String.valueOf(Integer.valueOf(etNum1.getText().toString())+Integer.valueOf(etNum2.getText() + ""));

Change it to like this.
exerciseStr = etNum1.getText().toString() + " + " + etNum2.getText().toString() + " = " + String.valueOf(Integer.valueOf(etNum1.getText().toString())+Integer.valueOf(etNum2.getText() + ""));

Checking if a button is disabled or not

my issue i am having is that selenium is saying that the next arrow button is enabled when it is disabled/grayed out. what i am trying to do is this
1 click next arrow button
2 sleep for 5 seconds
3 check if disabled
4 click next arrow button
5 check if disabled
( loop repeat steps 1 -5)
if button is disabled break do while loop
my code that is not working is below
PS_OBJ_CycleData.Nextbtn(driver).click();
Thread.sleep(5000);
WebElement element = driver.findElement(By.id("changeStartWeekGrid_next"));
if (element.isEnabled()) {
System.out.println("Good next arrow enabled");
} else {
System.out.println("next arrow disabled");
PS_OBJ_CycleData.Cancelbtn(driver).click();
break dowhileloop;
}
my console output is "Good next arrow enabled" instead of going to the else statment.
Button HTML is here
<div id="changeStartWeekGrid_next" class="paginationButton" disabled="disabled" data-xpal="xpath-selected">
<a tabindex="0" href="#" id="changeStartWeekGrid_next_link" onclick="var registry = require('dijit/registry'); registry.byId('changeStartWeekGrid').next(); return false;">
<span class="icon-pagination-next"></span>
</a>
</div>
As you can see the button is actually disabled there another way to check is button is really disabled? Any help would be appreciated.
this is an additional picture of the inspected element

The documentation for isEnabled.
Sadly, using the isEnabled method doesn't work in this case, as stated by the documentation:
This will generally return true for everything but disabled input elements.
A proper alternative is using JavaScript to check for the attribute's existence, and its value. You can inject JavaScript through the executeScript method of the webdriver classes. The first argument is the script, all following arguments are passed to the script, accessible as arguments[i], ...
For example:
Boolean disabled = driver.executeScript("return arguments[0].hasAttribute(\"disabled\");", element);

I In this case since i did not have an actual button I needed to find it attribute to see if it was disabled or not.
PS_OBJ_CycleData.Nextbtn(driver).click();
Thread.sleep(4000);
// check is arrow button is disabled
if (driver.findElement(By.id("changeStartWeekGrid_next")).getAttribute("disabled") != null) {
PS_OBJ_CycleData.Cancelbtn(driver).click();
break dowhileloop;
}

You can check it with this simple code:
Boolean isbutton;
isbutton=button1.isEnable()

Make sure you have the correct element. I've wasted hours trying to figure out why an element was enabled when it shouldn't have been, when I was actually looking at the wrong one! Inspecting the element in the browser did not help, because it wasn't the same element that the java code was looking at. The following code turned out to be helpful:
System.out.println("Actual element=" + describeElement(yourElement));
public static String describeElement(WebElement element) {
String result = "";
if (element == null ) {
log.error("Could not describe null Element");
return "null";
}
// Look for common attributes, such as id, name, value, title, placeholder, type, href, target, role, class,
String id = element.getAttribute("id");
String name = element.getAttribute("name");
String value = element.getAttribute("value");
String title = element.getAttribute("title");
String placeholder = element.getAttribute("placeholder");
String type = element.getAttribute("type");
String href = element.getAttribute("href");
String target = element.getAttribute("target");
String role = element.getAttribute("role");
String thisClass = element.getAttribute("class");
result = "WebElement [tag:" + element.getTagName() + " text:'" + limit(element.getText()) + "' id:'" + id + "' " +
(StringUtils.isEmpty(name) ? "" : (" name:'" + name + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" value:'" + value + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" title:'" + title + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" placeholder:'" + placeholder + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" type:'" + type + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" href:'" + href + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" target:'" + target + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" name:'" + name + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" role:'" + role + "' ")) +
(StringUtils.isEmpty(name) ? "" : (" class:'" + thisClass + "' ")) +
" isDisplayed: " + element.isDisplayed() +
" isEnabled: " + element.isEnabled() +
" isSelected: " + element.isSelected() + "]";
return result;
}

Bolding specific text

I'm trying to bold some text in a setter, but when it's displayed, it's not working. I'll just jump into some code so it makes sense...
private static class Spell {
private final String name;
private final String school;
private final String display_class;
//etc.
.
Text t = new Text("TEST: ");
t.setStyle("-fx-font-weight: bold;");
this.name = name + "\n\n";
this.school = school + "\n";
this.display_class = t + display_class + " " + spell_level + "\n";
//etc.
Displaying the list:
if (!newValue.isHeader()) {
tooltip.setText(newValue.getName() + newValue.getSchool() + newValue.getDisplay_Class() //etc.
The text is displayed within a ScrollPane as a Text object: Text tooltip = new Text();
The list displays values like Level: 0 Range: 25ft etc. With this setup, is it at all possible to make just the "Level:" and "Range:" parts bold? Currently, what is displayed when it prints t is Text[text="TEST: ",x=0.0,y=0.0, alignment=LEFT, origin=BASELINE, boundsType=LOGICAL...etc. etc, yet when adding t to a pane and displaying it that way, it shows up correctly bolded. I don't know what to do at this point.

Text t = new Text("TEST: ");
...
this.display_class = t + display_class + " " + spell_level + "\n";
In the line above, you are concatenating the output of toString() of your Text object instance (t) with other strings, that where your extra junk comes from, and it is not probably what you wanted to do.
Unfortunately Text won't support multistyle text strings.

Univocity Parsers: Calling a function from here is not working: parserSettings.selectFields( *some_function* );

I am using a .csv file and would like to pass a string constructed by a function to: parserSettings.selectFields( function );
During testing, when the string returned by the function is pasted directly into: parserSettings.selectFields( string ); the parsing works fine, however, when the function is used instead, the parse doesn't work, and there is only output of whitespace.
Here is the function:
public String buildColList() {
//Parse the qty col names string, which is a comma separated string
String qtyString = getQtyString();
List<String> qtyCols = Arrays.asList(qtyString.split("\\s*,\\s*"));
String colString = StringUtils.join(qtyCols.toArray(), "\"" + ", " + "\"");
String fullColString;
fullColString = "\"" + getString1() + "\"" + ", " + "\"" + getString2() + "\"" + ", " + "\"" + colString + "\"" + ", " + "\"" + getString4 + "\"";
return fullColString;
}
Here is how it is placed:
parserSettings.selectFields(buildColList());
Any help would be greatly appreciated, thanks.

You need to return an array from your buildColList method, as the parserSettings.selectFields() method won't split a single string. Your current implementation is selecting a single, big header instead of multiple columns. Change your method to do something like this:
public String[] buildColList() {
//Parse the qty col names string, which is a comma separated string
String qtyString = getQtyString();
List<String> qtyCols = Arrays.asList(qtyString.split("\\s*,\\s*"));
String colString = StringUtils.join(qtyCols.toArray(), "\"" + ", " + "\"");
String[] fullColString = new String[]{getString1(), getString2(), colString, getString4};
return fullColString;
}
And it should work. You might need to adjust my solution to fit your particular scenario as I didn't run this code. Also, I'm not sure why you were appending quotes around the column names, so I removed them.
Hope this helps.

How to use JOptionPane to display info

I need some help writing a program
Using this code I am able to enter in a track name, artist, etc.
I have a problem that I cannot now show this information in JOptionPane to display all of my info
import java.util.Scanner;
import javax.swing.JOptionPane;
public class TestTrack
{
public static void main(String[] args)
{
Scanner myScan = new Scanner(System.in);
System.out.println("Track name");
String name = myScan.nextLine();
System.out.println("Artist");
String Artist = myScan.nextLine();
System.out.println("Track length seconds");
String seconds = myScan.nextLine();
System.out.println("Album");
String Album = myScan.nextLine();
JOptionPane.showMessageDialog(null,"Trackinfo:")
}
}
So I guess I would want the pop out window to say
Track Name: "blank"
Artist: blank
Another question I have is how to ask this question multiple times by using "while" and asking if I would like to add another track
Sorry if I am using any terminology incorrectly I just started to learn Java

This line: JOptionPane.showMessageDialog(null,"Trackinfo:")
Contains what the pop-up window will contain. You pass in what you want its contents to be as the 2nd parameter, which is currently "Trackinfo".
To incorporate a while loop, you'll have to have a loop control variable, or a condition that will break the loop. In my example I used a string. My example uses a while loop that will continue as long as the string is not equal to "quit".
String test = "";
while( ! test.equals("quit") ) {
//use Scanner to get the next value the user enters
//ask for track info
//display that info in a message box
}

To obtain this:
Note: the texts of the OK and Cancel buttons are localized, if your computer is set to US locale you doesn't see 'Annuler"... ;-)
code this:
int answer = 0;
do {
/*----------------------------------------------------------------------------
Here you put the code which set the variables name, artist, seconds... (1)
----------------------------------------------------------------------------*/
final String title = "Track info";
final String message =
"<html><table>" +
"<tr><td>Track name" + "</td><td>" + name + "</td></tr>" +
"<tr><td>Artist" + "</td><td>" + artist + "</td></tr>" +
"<tr><td>Track length seconds</td><td>" + seconds + "</td></tr>" +
"<tr><td>Album" + "</td><td>" + album + "</td></tr>" +
"</table>";
answer =
JOptionPane.showConfirmDialog(
null, message, title, JOptionPane.OK_CANCEL_OPTION );
} while( answer == JOptionPane.OK_OPTION );
(1) You may choose Scanner or GUI whith JOptionPane.showInputDialog()

JOptionPane.showMessageDialog(null,"Trackinfo:" + "\nArtist: " + Artist + "\nseconds: " + seconds + "\nAlbum: " + Album)
Each '\n' means a new line. for doing this multiple times, you should place your code in a while loop, something like this:
while(!(Artist == "end")) {
//your code
}

Use myScan.next() instead of myScan.nextLine()
To output the information into the Message Dialog, use
String trackInfo = "Track Name: " + name + " | Artist : " +artist+ " | Track Length: " + seconds + " | Album: " + album;
JOptionPane.showMessageDialog(null, trackInfo, "Trackinfo", JOptionPane.INFORMATION_MESSAGE);
