Can't compare button icon to another icon

I am overriding the actionListener. All of the buttons besides "playbutton" have an image attached as an icon (button1, button2, button3). Every time a button is pressed, it should compare its icon to the prepared ImageIcon "livePicture" and if they are the same, it should go with the "Escaped()" method. Otherwise, the program will run the "Died()" method.
However, at least with the current code, it only uses "Died()". This, I guess, means that there is something wrong with the ifs that compare the images, but that is the only way of comparison I found on the internet.
Also, keep in mind that this is my first project, so it may seem a little cluttered.

EDIT:
Here is also an example of what vector could go as an "event" in "AppendQuest"
Vector<String> items2 = new Vector<>();
items2.add("You are kind of disoriented. What will you use to find the right way?" +
" moss, sun or tree barks");
items2.add("Unfortunately you didn't orient yourself well enough. Now, you " +
"will roam through the forest forever.");
items2.add("res/orientation_sun.png");
items2.add("res/orientation_moss.png");
items2.add("res/orientation_sun.png");
items2.add("res/orientation_tree_bark.png");

You can compare Objects with the .equals(Object) function:
if(!button.getIcon().equals(livePicture))
{
Died();
}
else
{...}
The == operator checks the identity of objects or the value of native types (e.g. int).
That means:
int nr1 = 1;
int nr2 = 1;
if(nr1 == nr2) {...} //true -> int is a native type
String str1 = "test";
String str2 = "test";
if(str1 == str2) {...} //false -> Same content but not same objects
if(str1.equals(str2)) {...} //true -> Same content, different objects
//Edit:
Another problem might be that you remove the image-url from your vector while creating the livePicture:
livePicture = ImageSize(50, 50, event.remove(0));
The url is not in the list anymore when you create your buttons. The result is that the buttons will never have the same image as your livePicture has, unless you're changing it (do you?).

how can I use JTextField and JLabel together?

I need a text field on a label but when i run this code there is no text field on the screen. How can i fix it.
JFrame jf = new JFrame() ;
JPanel panel = new JPanel() ;
JLabel label = new JLabel() ;
JTextField tField = new JTextField("asd" , 10) ;
label.add( tField ) ;
panel.add( label ) ;
jf.setSize( 500,400 ) ;
jf.add( panel ) ;
jf.setVisible(true) ;

JLabel's have no default layout manager, and so while your JTextField is being added tot he JLabel, it's not showing because the label has no idea how to show it.
There can be several ways to solve this depending on what you're trying to achieve:
Give the JLabel a layout manager, and then add the JTextField to it: but then the JTextField covers the JLabel, its text (if it has any) and its icon (if it has one), not good.
Create a JPanel to hold both, and give it an appropriate layout manager: probably a good bet.
Add them both to the same JPanel, using a layout manager that can easily place them in association: another good bet. GridBagLayout works well for this.
Don't forget to also call the JLabel's setLabelFor(...) method to associate it tightly with the JTextField, as per the JLabel Tutorial
For example:

JTextField textField = new JTextField(10);
label.setDisplayedMnemonic(fieldTitle.getMnemonic());
label.setLabelFor(textField);

gbc.weighty = 1.0;
return gbc;
}
public String getFieldText(FieldTitle fieldTitle) {
return fieldMap.get(fieldTitle).getText();
}
}
Which displays as
Note that the JLabels have underlines on mnemonic chars, chars that when pressed in alt-key combination will bring the focus to the JTextField that the JLabel was linked to via, setLabelFor(...), and is caused by this code:
FieldTitle fieldTitle = FieldTitle.values()[i]; // an enum that holds label texts
JLabel label = new JLabel(fieldTitle.getTitle() + ":", JLabel.LEFT); // create JLabel
JTextField textField = new JTextField(10); // create JTextField
// set the label's mnemonic -- brings focus to the linked text field
label.setDisplayedMnemonic(fieldTitle.getMnemonic());
// *** here we *link* the JLabel with the JTextField
label.setLabelFor(textField);

Accessing values of individual JTextFields created in a loop

Here is how I created the labels and JTextFields:
JPanel panel3 = new JPanel(new SpringLayout());
String[] labels = {"Non-animated image name:","Left animation image name:","Top animation image name:",
"Right animation image name:","Bottom animation image name:"};
for(int i=0; i<labels.length; i++){
JLabel l = new JLabel(labels[i],JLabel.TRAILING);
JTextField n = new JTextField(10);
panel3.add(l);
l.setLabelFor(n);
panel3.add(n);
}
SpringUtilities.makeCompactGrid(panel3,
5, 2,
6, 6,
6, 6);
Say for example, how would I access/get the value of the text in the JTextField with the label, "Top animation image name:"?
I know that usually, one can perform JTextField.getText(), but to me it looks like that wouldn't work here.
Thanks in advance!

This is just a specific example of the question:
how can I access an object created in a loop.
The answer is the same: put them in a collection or array. Note that the collection option has greater flexibility. For instance if you create a bunch of JLabel/JTextField associations, you could use a HashMap<String, JTextField> to associate the JTextField with a String.
For example:
Map<String, JTextField> fieldMap = new HashMap<String, JTextField>();
String[] labels = {"Non-animated image name:","Left animation image name:","Top animation image name:",
"Right animation image name:","Bottom animation image name:"};
for(int i=0; i<labels.length; i++){
JLabel l = new JLabel(labels[i],JLabel.TRAILING);
JTextField n = new JTextField(10);
panel3.add(l);
l.setLabelFor(n);
panel3.add(n);
fieldMap.put(labels[i], n);
}
// and then later you can get the text field associated with the String:
String text = fieldMap.get(labels[2]).getText();

Each time you create a JLabel and a JTextField, store references to each of them inside a new instance of a container class.
For example:
private class LabelTextFieldContainer {
JLabel label;
JTextField textField;
//Constructor goes here...
}
for(int i=0; i<labels.length; i++){
JLabel l = new JLabel(labels[i],JLabel.TRAILING);
JTextField n = new JTextField(10);
panel3.add(l);
l.setLabelFor(n);
panel3.add(n);
containerList.add( new Container(l, n) ); //Instantiate List<LabelTextFieldContainer> containerList somewhere else
}

Refreshing the content pane through an action listener in java

I have a problem while refreshing the content pane of my GUI. I can create a listener that is executed, but I can't manage to access the content pane to update it. Here is my code so far:
Egutegia() and Hasiera() and constructors for JPanels with different data. They load correctly when set to variable centralData from the beggining. My goal is to change between one another when clicking the buttons with their name. So far I only tried to implement one.
The action listener is written in the later part. It prints "reaches here" correctly. However, I dont know how to acces the content pane (content) from there and redraw the corresponding JPanel.

setLocation of Label

I have all of the labels working correctly but the userLabel[3] is not positioning properly
No matter what I do, the label "Color:" always shows up on the frame with a x-coordinate of 0 and a y-coordinate that is half way down the frame.
JLabel[] userLabel = new JLabel[4];
for(int p = 0; p < userLabel.length; p++){
userLabel[p] = new JLabel();
userLabel[p].setSize(100,50);
frameSetUp.add(userLabel[p]);
}
userLabel[0].setText("Width of Frame:");
userLabel[1].setText("Height of Frame:");
userLabel[2].setText("# OF Balls:");
userLabel[3].setText("Color:");
userLabel[0].setLocation(10,35);
userLabel[1].setLocation(10,85);
userLabel[2].setLocation(10,135);
userLabel[3].setLocation(0,0); //no matter what coordinates I change this too, it wont reposition

Don't use setLocation, setBounds, null layouts or absolute positioning.
Instead use the layout managers including perhaps nested JPanels, each using its own layout manager to achieve pleasing easy to maintain GUI's.
For more help, show a picture of what you're trying to achieve, what you actually are achieving, and post a minimal working example, code that is small, that compiles and runs, and shows us your problem.

}
});
}
}
Which will display like so:
The beauty of this code, is if you wish to add another field, say a line thickness field, and want to add it so that it is second to last, then the only change needed to the code would be to change this:
String[] labelTexts = new String[] { "Width of Frame:",
"Height of Frame:", "# OF Balls:", "Color:" };
to this:
String[] labelTexts = new String[] { "Width of Frame:",
"Height of Frame:", "# OF Balls:", "Line Thickness:", "Color:" };
Which results in:
No need to have to calculate how to change the Color label or JTextField's locations as the layout manager does all the hard work for you.

Finally got the answer try increasing the size of the JLabel array by 1 and run it will work fine
