Java 使用JOptionPane打印报告

好的，现在我得到了要编译和运行的代码，但是现在输出是不正确的。我需要能够选择一个选项，然后为2，3有3个额外的选项后，选择该选项。我应该如何调整我的编码来做到这一点

任务：

所有信息列表

特定医生的所有手术列表（提示医生）

特定类型的所有手术列表（提示输入手术类型）

支付给每位医生的手术费总额

平均费用

数据文件（patient.txt）：

迄今为止的代码供参考：

对于（i=0；i使用
String
或
StringBuilder
或
StringBuffer
来执行此操作。但是不要使用
StringBuilder
或
StringBuffer
。因为对于
String
，您需要一些额外的对象来进行
String
操作

Ex:

StringBuilder sb = new StringBuilder();
sb.append("Id ").append(" Name\n");
for (int i = 0; i < 10; i++) {
    sb.append(i).append("  Name"+i).append('\n');

为什么你不能用
JTextArea
和
JScrollPane
来代替
JOptionpane
来使用其他组件，比如
JTextArea
和
JScrollPane
来代替
JOptionpane
。那么我应该把它添加到我当前的字符串方法中，还是用它来代替呢？编辑：我有点生气ty是oop的新手。在我大学毕业之前，我一直在努力提高我的技能。我的建议是，使用
StringBuilder
而不是
String
。私有字符串菜单（）{放在这里？是的，我是说用
StingBuilder
来代替它。现在开始实施。我会加上你的答案
