Trying to display output from an ArrayList in JTextArea

Question

I'm storing user input into an ArrayList of a class BarInfo. The class takes in multiple data: Strings, booleans, ints. Then I want to display the data stored in the order it was entered in a JTextArea. Now say the user inputs data for one bar with all the necessary information. When they display the data it works right. However, if more than one bar is inputted, or another bar is added afterwards, it displays multiple versions of the data with different data.

For example if two bars are entered the display will show both of the bars various times with different amounts of int data from both of them mixed, instead of just The first bar and then the second.

This is my class Bar:

class BarInfo
{
    private final String barLoc, barName, v="Vodka", w="Whiskey", r="Rum", 
            g="Gin", b="Brandy"; 
    private final boolean music, food;
    private final int vCount, wCount, rCount, gCount, bCount;

    public BarInfo(String l, String n, boolean m, boolean f, int v, int w,
                    int r, int g, int b)
    {
        this.barLoc = l;
        this.barName = n;
        this.music = m;
        this.food = f;
        this.vCount = v;
        this.wCount = w;
        this.rCount = r;
        this.gCount = g;
        this.bCount = b;
    }

    @Override
    public String toString()
    {
        return "The bar is located at: " + barLoc + " \nThe bar is named: " + barName 
                + "\nLive Music: " + music + "\nFood Service: " + food + "\n"
                + "Liquor currently in stock (bottles):\n" + v + ": " +  vCount
                + "\n" + w + ": " + wCount + "\n" + r + ": " + rCount + "\n" 
                + g + ": " + gCount + "\n" + b + ": " + bCount + "\n\n";
    }

} 

And my display code:

for(int i=0; i<barList.size(); i++)
        {
            jTextAreaDisplay.append(jTextAreaDisplay.getText() 
                    + barList.get(i).toString() + "\n\n");

        }

I'm guessing my for loop is somehow off, but I'm not seeing it. Any help would be greatly appreciated.

UPDATE Output expected for say 2 bars:

The bar is located at: (barLoc)

The bar is named: (barName)

Live music: (true or false)

Food Service: (true or false)

Liquor currently in stock:

Vodka = (amount)

Whiskey = (amount)

Rum = (amount)

Gin = (amount)

Brandy = (amount)

Then the second bar with its data. What I'm getting is like 6-7 different bars from those two bar inputs.

Answer 1

JTextArea.append() appends text , so it's added to what is there already. Since you also append jTextAreaDisplay.getText() you'll get duplicates if the loop runs more than once.

Try:

for(BarInfo b : barList) { // Java foreach loop
    jTextAreaDisplay.append(b.toString() + "\n\n");
}
