JOptionPane 未正确显示消息

Question

我正在开发一个锻炼程序，该程序在用户通过 GUI (JOptionPane) 输入所需的锻炼练习后显示锻炼练习。

String name = JOptionPane.showInputDialog("Welcome to the workout and dietary health plan app, Enter your name");
        
        int age = Integer.parseInt(JOptionPane.showInputDialog("Hello " + name + ", what is your age? "));
        
        if(age < 60 && age > 15) {
            String typeAdvice = JOptionPane.showInputDialog("You are the right age to use this app, would you like advice on a workout plan, or a diet plan?");
            if(typeAdvice.contains("workout") || typeAdvice.contains("Workout")) {
                String group = JOptionPane.showInputDialog("What group would you like to workout?");
                if(group.contains("Chest") || group.contains("chest")) {
                    JOptionPane.showInputDialog(null,  "Chest Workouts: Bench Press, Incline Dumbbell Press, Bar Dips, Standing Cable Chest Fly");
                }
            }

当我运行程序时，我显示的第一个和第二个 if 语句按预期工作。但是，当它转到我的第三个 if 语句时，它失败了。基本上，我输入了所需的年龄和锻炼，但是当它问我输入“胸部”的组时，代码就终止了。

我的问题可能是 JOptionPane 没有显示消息或之前的代码吗？

谢谢
