How do I display the numbers in a for loop in a jLabel?

Question

    int intStartingNumber = Integer.parseInt(this.txtInputStartingNumber.getText());
    int intEndingNumber = Integer.parseInt(this.txtInputEndingNumber.getText());

    for (int x = intStartingNumber; x <= intEndingNumber; x = x + 1) {
        System.out.print(x + " ");
        this.lblOutputNumbers.setText(x + " ");
    }

Hi this is my code how come it won't set my jLabel as all the numbers in the for loop but when i print it out, all the numbers show up. In the jLabel only whatever is inputted as the EndingNumber is printed out in the jLabel.

for (int x = intStartingNumber; x <= intEndingNumber; x++) {
    System.out.print(x + " ");
    this.lblOutputNumbers.setText(lblOutputNumbers.getText() + " " + x);
}

The trick here is JLabel does not have an appendText function, but you can call the JLabel.getText() function inside of its setText function to append text to the label.
