无法将按钮图标与另一个图标进行比较

Question

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");

Answer 1

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 (eg 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?).
