使用JOptionPane打印報告

Question

好的，現在我可以編譯並運行代碼，但是現在輸出不正確。 我需要能夠選擇一個選項，然后對於2和3，在選擇了該選項之后，還有3個其他選項。 我應該如何調整我的編碼來做到這一點？

任務：

1. 全部信息一覽

2. 特定醫生的所有手術清單（提示醫生）

3. 特定類型的所有手術清單（提示手術類型）

4. 支付給每位醫生的手術費總額

5. 平均費用

數據文件（patient.txt）：

11111,Smith,Norris,Thyroid,1000.00    
11112,Obama,Norris,Lasek,500.00  
11113,Hoover,Norris,Dental,100.00  
11114,Cena,Norris,Lasek,500.00  
11115,Leto,Norris,Thyroid,1000.00  
22221,Clark,Bond,Thyroid,1000.00  
22222,Chang,Bond,Lasek,500.00

到目前為止的代碼可供參考：

Answer 1

使用String或StringBuilder或StringBuffer來執行此操作。 但是使用StringBuilder或StringBuffer代替String 。 由於是String ，因此需要一些額外的對象來進行String操作。

例如：

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');
}
JOptionPane.showMessageDialog(null, sb.toString());

使用HTML標記產生更好的格式化結果，例如<font> ， <table>等。

例如：

String startTag ="<font size='2' color='red'>";
String endTag = "</font>";
sb.append(startTag+"Some content"+endTag);
