java - 使用 JOptionPane 打印报告

Question

好的，现在我可以编译并运行代码了，但是现在输出不正确。我需要能够选择一个选项，然后对于 2、3，在选择该选项后还有 3 个附加选项。我应该如何调整我的编码来做到这一点？

任务:

1. 所有信息列表

2. 特定医生的所有手术列表(提示医生)

3. 特定类型的所有手术列表(提示手术类型)

4. 支付给每位医生的手术费用总额

5. 平均费用

数据文件(患者.txt):

11112,Obama,Norris,Lasek,500.00  
11113,Hoover,Norris,Dental,100.00

Answer 1

使用String或StringBuilder或StringBuffer去做这个。但不是 String使用 StringBuilder或StringBuffer 。由于String ，您需要一些额外的对象来 String操纵。

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标签以产生更好的格式化结果，例如 <font> , <table>等

例如:

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