java - Trouble passing an ArrayList of objects from one class to another -

-

i'm trying display 2 arraylists on jtextarea having troubles passing arraylist of objects 1 class another.

the part of code i'm having problems trying display info following code

private void jbuttondisplayactionperformed(java.awt.event.actionevent evt)                                                    {                                                            for(int i=0; i<bars.size(); i++)         {             jtextareadisplay.append(jtextareadisplay.gettext()                      + bars.get(i).tostring() + bars.get(i).getliquor.tostring()                      + "\n\n");          }     }

it says can't find symbol: variable getliquor bar class.

bar class code i'm trying pass it:

arraylist<liquor> liquors; private liquor liquor = new liquor(liquors); public liquor getliquor()     {         return liquor;     }

from other class liquor:

arraylist<liquor> liquors = new arraylist<>();   public liquor(arraylist<liquor> liquors) {     this.liquors = liquors;     this.vodka = getv();     this.whiskey = getw();     this.rum = getr();     this.gin = getg();     this.brandy = getb();     this.vcount = getvc();     this.wcount = getwc();     this.rcount = getrc();     this.gcount = getgc();     this.bcount = getbc(); }

the other contructor in liquor code (if relevant):

public liquor(string vodka, string whiskey, string rum, string gin,              string brandy, int v, int w, int r, int g, int b)     {         this.vodka = vodka;         this.whiskey = whiskey;         this.rum = rum;         this.gin = gin;         this.brandy = brandy;         this.vcount = v;         this.wcount = w;         this.rcount = r;         this.gcount = g;         this.bcount = b;     }

update

from can see, changed little bit , @ least names of liquor show, stock number each isn't been read in, instead shows null. think problem lies here:

public liquor(arraylist<liquor> liquors)     {          this.vodka = "vodka";         this.whiskey = "whiskey";         this.rum = "rum";         this.gin = "gin";         this.brandy = "brandy";         this.vcount = getvc();         this.wcount = getwc();         this.rcount = getrc();         this.gcount = getgc();         this.bcount = getbc();     }

i don't think getters working correctly. or maybe arraylist?

output:

the kendall bar named: kink live music: true food service: false liquor in stock:

vodka: 0

whiskey: 0

rum: 0

gin: 0

brandy: 0

you're missing parentheses getliquor method call:

bars.get(i).tostring() + bars.get(i).getliquor().tostring()
