java - Overflow JLabel into Another JLabel -


let's have jlabel sized 20x20. let's add string "the quick brown fox jumps on lazy dog." sentence long jlabel, gets replaces .... there way overflow jlabel, first jlabel have "the quick brown fox" , second jlabel have "jumps on lazy dog."?

jlabel lbl = new jlabel("the quick brown fox jumps on lazy dog."); lbl.setmaximumsize(new dimension(20, 20)); add(lbl)

produces label says "...".

it easier answer if provided more information.

i'm assuming want 2 labels can placed side side, or in other layout. in case first label's text overflows, second label display remainder.

here's solution:
