I'm trying to display all the values from a for loop into a label control in my application.
Problem is, its only displaying the last number. Can anyone please help.
Thanks

int lottoNumbers1 = Integer.parseInt(txtLotteryNumbers1.getText());
        int lottoNumbers2 = Integer.parseInt(txtLotteryNumbers2.getText());
        int lottoNumbers3 = Integer.parseInt(txtLotteryNumbers3.getText());
        int lottoNumbers4 = Integer.parseInt(txtLotteryNumbers4.getText());
        int lottoNumbers5 = Integer.parseInt(txtLotteryNumbers5.getText());
        //int lottoNumbers6 = Integer.parseInt(txtLotteryNumbers6.getText());
        int arrUserInput[] = {lottoNumbers1, lottoNumbers2, lottoNumbers3, lottoNumbers4, lottoNumbers5};
        int arrRnd[] = new int[5];
        Random rnd = new Random();
        for (int i = 0; i < arrRnd.length; i++) {
            arrRnd[i] = rnd.nextInt(49);
        boolean isfound = false;
        for (int i = 0; i < arrUserInput.length; i++) {
            isfound = false;
            for (int j = 0; j < arrRnd.length; j++) {
                if (arrUserInput[i] == arrRnd[j]) {
                    isfound = true;
            if (isfound) {
                //System.out.println("Same Numbers again : " +arrUserInput[i]);
                String numbers = Integer.toString(arrUserInput[i]);
                int res = NumberCount.wordcount(numbers);
                //System.out.println("Number of matches : " +res);
                switch (res) {
                    case 1:
                        lblNumbersEntered.setText("You matched 1 number " + arrUserInput[i] + " and win nothing");
                        System.out.println("Number of matches : " +res);
                        break;
                    case 2:
                        lblNumbersEntered.setText("You matched 2 number " + arrUserInput[i] + " and win £2");
                        System.out.println("Number of matches : " +res);
                        break;
                    case 3:
                        lblNumbersEntered.setText("You matched 3 number " + arrUserInput[i] + " and win £10");
                        System.out.println("Number of matches : " +res);
                        break;
                    case 4:

                        System.out.println("Number of matches : " +res);
                        break;
                    case 5:

                        System.out.println("Number of matches : " +res);
                        break;
                    default:
                        lblNumbersEntered.setText("You have matched no numbers");
                        System.out.println("Number of matches : " +res);
                        break;

If you want a complete history of each time you go through the loop, you have to construct the history:
[code]
myLabel.setText("This");
MyLabel.setText(" is");
myLabel.setText(" good");
[/code]
myLabel will contain only " good", since that is what myLabel was set to last, but if you want the history:
[code]
myLabel.setText("This");
MyLabel.setText(myLabel.getText() + " is");
myLabel.setText(myLabel.getText() + " good");
[code]
Should give you "This is good", as each time the contents of myLabel are retrieved and appended before myLabel is given the new set value.
