Question

我创建了一个类，该类使您可以将文件信息存储在每行的单独数组中，并分别显示它们。我想知道是否有一种方法可以从此数据的不同标题下创建JTable，以便可以将其从此信息转换为表，以后可以通过执行诸如从该文件添加和删除行之类的操作来操纵它？这是我所做的如此之遥：

public class STIAdemo {

private static BufferedReader br;
public static void main(String[] args) throws Exception {
  br = new BufferedReader(new FileReader("Roadslist"));
  ArrayList<String[]> lines = new ArrayList<String[]>();
  for(String line = br.readLine();line != null;line = br.readLine()) {
      //comma will be replaced with .
      line=line.replaceAll(",","\\.");
      //each line will be stored in an array with . as separator
      String[] fields = line.split("\\.");
      //System.out.println(" " + fields[0]);
      lines.add(fields);
  }
  String[][] strings = (String[][]) lines.toArray(new String[lines.size()][]);
  System.out.println("Total Lines: " + strings.length);

  //code to display
  for(String s[]:strings){
      for(String ss:s){
          System.out.print(ss+", ");
      }
      System.out.println();
  }
 }
}

我在类似的道路上有信息

Epinal Way 0, Alan Moss Rd Roundabout, Epinal-Garendon, 0.16, 40, no, -1, flawless
Epinal Way 1, Epinal-Garendon, Ashby Rd Roundabout, 0.13, 36, no, -1, impaired
Epinal Way 2, Ashby Rd Roundabout, Epinal-University, 0.1, 36, no, -1, flawless
Epinal Way 3, Epinal-University, Epinal-Radmoor, 0.13, 36, no, -1, flawless
Epinal Way 4, Epinal-Radmoor, Epinal-Forest, 0.3, 36, no, -1, flawless
Westfield Drive, Ashby Rd Roundabout, Radmoor-Westfield, 0.39, 20, no, -1, flawless, yes, yes, yes, no, no, no

，我想将其转换为一个类似于以下内容的表：第一行的类别对应于每个字段的部分。

Name Intersection 1 Intersection 2 Road name 3 Distance Speed one way? height, Epinal Way 0, Alan Moss Rd Roundabout, Epinal-Garendon, 0.16, 40, no, -1, flawless
