java - How can I generalize these repetitive blocks of code? -

code near-identical blocks makes me cringe. plus adds have thousand lines of code half suffice. surely there way make loop make happen , not have code looks unsophisticated , brainless.

offhand seems adding code seek reduce: loop make 5 buttons, array of labels buttons, array of backgrounds... maybe more. if turned out acceptable, how make loop handle listeners? i can't have array of methods, can i? guess such loop have include switch. yes? i'd if didn't want seek better solution. i'm asking...

what code listen entire group of buttons , take action based on 1 pressed? component assign single listener? , how?

(there's chance answer question make me cringe more repetitive nature of code, if realize know how , needn't have asked in first place, i'm asking anyway. i'm @ 1 of i've-had-it-for-today points brain wants out.)

  private void makescoremasterbonuses(){     pnlbonuses = new jpanel(new gridlayout(1, 6));     pnlbonuses.setsize(6,1);      jbutton t1 = (new jbutton("3w"));     t1.settooltiptext("this triple-word cell.");     t1.setbackground(triple_word);     t1.sethorizontalalignment(jbutton.center);     t1.addactionlistener(new actionlistener() {       @override public void actionperformed(actionevent e) {         highlighter.shadesymmetric(currentcell,triple_word);       }});      jbutton t2 = (new jbutton("3l"));     t2.settooltiptext("this triple-letter cell");     t2.setbackground(triple_letter);     t2.sethorizontalalignment(jbutton.center);     t2.addactionlistener(new actionlistener() {       @override public void actionperformed(actionevent e) {         highlighter.shadesymmetric(currentcell,triple_letter);       }});      jbutton t3 = (new jbutton("2w"));     t3.settooltiptext("this double-word cell");     t3.setbackground(double_word);     t3.sethorizontalalignment(jbutton.center);     t3.addactionlistener(new actionlistener() {       @override public void actionperformed(actionevent e) {         highlighter.shadesymmetric(currentcell,double_word);       }});      jbutton t4 = (new jbutton("2l"));     t4.settooltiptext("this double-letter cell");     t4.setbackground(double_letter);     t4.sethorizontalalignment(jbutton.center);     t4.addactionlistener(new actionlistener() {       @override public void actionperformed(actionevent e) {         highlighter.shadesymmetric(currentcell,double_letter);       }});      jbutton t5 = (new jbutton(""));     t5.settooltiptext("no bonus");     t5.setbackground(white);     t5.sethorizontalalignment(jbutton.center);     t5.addactionlistener(new actionlistener() {       @override public void actionperformed(actionevent e) {         highlighter.shadesymmetric(currentcell,b_normal);       }});      pnlbonuses.add(new jlabel("legend: "));     pnlbonuses.add(t1);         pnlbonuses.add(t2);          pnlbonuses.add(t3);          pnlbonuses.add(t4);          pnlbonuses.add(t5);    } 

i'm not asking write code; wouldn't want (but couldn't ignore it!).

here's code above does:

generally time have repeated functionality that, want extract code out helper method this:

private jbutton makejbutton(string label, string tooltip, color bgcolor, final color highlight) {     jbutton button = new jbutton(label);     button.settooltiptext(tooltip);     button.setbackground(bgcolor);     button.sethorizontalalignment(jbutton.center);     button.addactionlistener(new actionlistener() {         @override         public void actionperformed(actionevent e) {             highlighter.shadesymmetric(currentcell, highlight);         }     });     return button; } 

then makescoremasterbonuses() method becomes simpler:

private void makescoremasterbonuses() {     pnlbonuses = new jpanel(new gridlayout(1, 6));     pnlbonuses.setsize(6, 1);      pnlbonuses.add(new jlabel("legend: "));     pnlbonuses.add(makejbutton("3w", "this triple-word cell.", triple_word, triple_word));     pnlbonuses.add(makejbutton("3l", "this triple-letter cell.", triple_letter, triple_letter));     pnlbonuses.add(makejbutton("2w", "this double-word cell.", double_word, double_word));     pnlbonuses.add(makejbutton("3l", "this double-letter cell.", double_letter, double_letter));     pnlbonuses.add(makejbutton("", "no bonus.", white, b_normal)); }
