Question

我有一个JavaFX表，我想为每一行添加一些数据。数据来自文本文件。这是应该将每个数据片段输入特定单元格的代码文件中的每一行都采用以下格式：

firstName;LastName;SchoolName;email;year;active?;amountOwed;

基本上每一行都是表格中的一行。

try{
        ArrayList<String> allLinesOfTheFile= new ArrayList<String>();
        String path = "G:\\";
        String line;
        File masterFile = new File(path,"masterfile.txt");
        BufferedReader readMasterFile = new BufferedReader(new FileReader(masterFile));

        while ((line = readMasterFile.readLine()) != null) {

            for (String data: line.split(";")){

                //this splits the data into individual pieces, each piece will take up one cell in the table

            }

        }


    }

Here is the tableview

您必须创建一个模型类来保存值。这是一个可以使用的小例子

模特课程：

public class Model {

    private String col1;
    private String col2;

    public Model(String[] st){
        this.col1 = st[0];
        this.col2 = st[1];
    }
    public String getCol1() {
        return col1;
    }

    public void setCol1(String col1) {
        this.col1 = col1;
    }

    public String getCol2() {
        return col2;
    }

    public void setCol2(String col2) {
        this.col2 = col2;
    }

}

您的控制器类

  ObservableList<Model> lst = FXCollections.observableArrayList();
    String path = "G:\\";
    String line;
    File masterFile = new File(path,"masterfile.txt");
    BufferedReader readMasterFile = new BufferedReader(new FileReader(masterFile));

    while ((line = readMasterFile.readLine()) != null) {

          String[] data =line.split(";");
          Model md= new Model(data);
          lst.add(md);
   }
   table.setItems(lst);
