duplicate random numbers JAVA

Question

In this code, when a button is pressed, it shows a random number. I don't want that number to repeat itself. I have it so that when a big button is pushed, a number generates 1-10. I want it so that IF that number is duplicated it runs the code again to find another number that works. I've been working on it for a while and tried a lot of things. Any tips/tricks would be great. Thank you.

class HiLow extends JFrame implements ActionListener{
    int NumberGenerated;
    JButton Push, High,Low, Bank;
    JLabel Score;
    int helpInt = 0;
    int counterInt = 0;
    ArrayList<Integer> numberList = new ArrayList<Integer>();
    int size = numberList.size();
    boolean hp = true;

    HiLow(){
        JFrame l = new JFrame();
// JOptionPane.showMessageDialog(l, "Press the 'Push' button\nThen look at the number rolled\nThere will be numbers from 1-10\nThen click higher or lower\nYou can bank your points using the bank button\nMost points after 5 spins wins\nGood luck!");
        Push = new JButton("Push For Number");
        High = new JButton("Higher");
        Low = new JButton("Lower");
        Bank = new JButton("Bank Points");
        Score = new JLabel("");

        add(Push);
        add(High);
        add(Low);
        add(Bank);
        add(Score);

        Push.addActionListener(this);
        High.addActionListener(this);
        Low.addActionListener(this);
        Bank.addActionListener(this);
