I am learning java and i am pretty new for it. I am trying to create a static profile window using swing. Also, the avatar picture should change depending on user and user information should be read from a text file. This code doesnt give a error but its because of avatarPath. I think the program thinks its non-static.

Edit: I changed code a bit and it gives error. Edit2: what I am trying to do is creating users and their profiles. Profile will contain avatar image and 3 variable which are name, surname and gender. I want to display them with respect to users.
I am living problems with this codes;
static void AvatarPic(){
if( x == 0 ){
avatarPath = "\"/Users/hei_cosplay_darker_than_black_by_seras0victoria.jpg\"";
}
else if( x == 1 ){
avatarPath = "\"/Users/lyralei_the_windrunner_by_trungth-d5zhmc1.jpg\"";
}
else if( x == 2 ){
avatarPath = "\"/Users/shingeki_no_kyojin_by_asuka10-d6k762k.jpg\"";
}
}
and
ProfilePanel.AvatarPic();
jLabel1.setIcon(new
javax.swing.ImageIcon(getClass().getResource(ProfilePanel.avatarPath)));
There are many problems in your code.
The initComponents() is not a static function .I guess in your static conversion you just replaced every function with public static .And the below is a constructor [I'm sure because it is a Netbeans generated one] and you have modified it also.No need to do that
public static void ProfilePanel() {
initComponents();
}
You can change it back to the way it was
public ProfilePanel() {
initComponents();
}
You'll get a java.lang.NullPointerException at
jLabel1.setIcon(new javax.swing.ImageIcon(getClass().getResource(ProfilePanel.AvatarPic())));
because if you are using getResource you just have to specify the filename relative to the package.If you'll be loading from other location,then you have to change it like
jLabel1.setIcon(new javax.swing.ImageIcon(ProfilePanel.AvatarPic()));//file location
Also you have to give the absolute path
avatarPath = "D://hei_cosplay_darker_than_black_by_seras0victoria.jpg";
You'll again get a java.lang.NullPointerException at
permitedUser[0] = new UsersInfo(s1[0], s1[1], s1[2]);
because you haven't initialized the permitedUser anywhere.So you have to do it like
static UsersInfo permitedUser[]=new UsersInfo[3];
After making those changes and if you run it with 0 then BK201[Code Name Hei] will be on your screen
And Your Edited FullCode[Make change to ImageLocations]
