Basic Java Swing - adding JLabels with icons at runtime -


i'm making grid containing icons representing game map, , grid need redrawn. i'm working way basics. here's code got working

    int = 1;     while (i < 50) {             pnlmap.add(new jlabel(string.valueof(i)));         += 1;     }

now want jlabels display icons, can't figure out syntax arguments on pnl.add()

i imagine it's like

pnlmap.add(new jlabel("").seticon(new imageicon(clientgui.class .getresource("/resources/wall.jpg"))));

as can guess doesn't work. error: the method add(component) in type container not applicable arguments (void)

how above code add jlabels icons?

(on separate note, what's kind of object construction called, "add new jlabel" dynamically rather initialising before?)

unlike constructor jlabel, seticon function doesn't return (or returns void). means code looks bit this:

pnlmap.add(void);

which why error being thrown.

therefore, slight modification of code needed make loop work.

int = 1; while (i < 50) {     jlabel label = new jlabel(string.valueof(i));     label.seticon(new imageicon(clientgui.class .getresource("/resources/wall.jpg")));     pnlmap.add(label);     += 1; }

edit: in answer question new jlabel() construction in code. is, surprisingly, called dynamic object construction.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
