Question

从CDN链接给我一个看起来很奇怪的导航栏。但是，从本地文件链接可以得到正确的输出。

ArrayList<Item> available = new ArrayList<Item>();
for(int i = 0; i < 5; i++){
    available.add(new Item("Event " + i, "Year " + i, "Description " + i));
}

JTable table = new JTable(model);
table.addMouseListener(new java.awt.event.MouseAdapter() {
    @Override
    public void mouseClicked(java.awt.event.MouseEvent evt) {
        int row = table.rowAtPoint(evt.getPoint());
        int col = table.columnAtPoint(evt.getPoint());    
        if (row >= 0 && col == 2 && canPlay) {
            clickedYear = (String)data[row][col];
            if(clickedYear.equals(answerYear)){ 
                answeredResult = 1;                        
            }else{
                answeredResult = -1;
            }
        }
     }
});

while(available.size()!=0){
    promptPanel.removeAll();
    answeredResult = 0; //0-unanswered 1-correct 2-incorrect

    int random = (int)(Math.random()*(available.size()-1));
    JLabel label = new JLabel(available.get(random).getEvent()+"\n");
    promptPanel.add(label);    
    canPlay = true;    

    //wait for mouse clicked before proceeding to the next code

    if(answeredResult == 1){
        JLabel correct = new JLabel("Correct!");
        promptPanel.add(correct);
    }else if(answeredResult == -1){
        JLabel wrong = new JLabel("Wrong.");
        promptPanel.add(wrong);
    }

    revalidate();
    repaint();           
    available.remove(random);
}

我在macOS Sierra版本10.12.4（16E195）下使用Safari版本10.1（12603.1.30.0.34）

我做错了什么？
