我正在制作一个“保存”＃39;到特定文件并打开＆＃39;来自特定文件。保存功能正在运行，但由于我已经实施了“打开”功能。功能现在已停止工作。运行打开功能时，我将其内容打印到控制台，但此时控制台中显示以下错误，控制台中只显示数组列表的第一项。 ＆＃39;开放＆＃39;并且＆＃39;保存＆＃39;功能就在我的代码的底部，但就在我的两个课程之前＆＃39; Record＆＃39;和＆＃39; Getrecord＆＃39;这些用于“保存”。并且＆＃39;打开＆＃39;功能。我很困惑，不知道如何继续，因为我不知道什么是错的。
代码如何显示：
miOpen.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent arg0) {
FileInputStream fis=null;
try{
fis = new FileInputStream("testsave.txt");
}
catch (FileNotFoundException e){
e.printStackTrace();
}
System.out.println("TEST OPEN B4");
String openstring = new String();
BufferedReader bwo = new BufferedReader(new InputStreamReader(fis));
try {
while( (openstring=bwo.readLine()) != null) {
String [] g = openstring.split(",");
System.out.println("TEST OPEN");
System.out.println(openstring);
getrecordsarray.add(new Getrecord(g[0], Double.parseDouble(g[1]), Double.parseDouble(g[2]), Double.parseDouble(g[3]), Double.parseDouble(g[4]), Double.parseDouble(g[5]), Double.parseDouble(g[6]), Double.parseDouble(g[7])));
}
} catch (NumberFormatException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
fis.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}});
miSave.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent arg0) {
fileChooser.setTitle("testsave1.txt");
try (BufferedWriter bw = new BufferedWriter(new FileWriter("testsave1.txt", true))) {
for(Record r : records)
bw.write(r.name + "," + r.age + "," + r.gender + "," + r.ethnicity + "," + r.answerA + "," + r.answerB + "," + r.answerC + "," + count);
bw.newLine();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("SAVED");
if (autoreturn==1){
System.out.println("saved fade");
FadeTransition ft = new FadeTransition(Duration.millis(3000), savemsg1);
ft.setFromValue(0);
ft.setToValue(1);
ft.play();
FadeTransition ft2 = new FadeTransition(Duration.millis(3000), savemsgl1);
ft2.setFromValue(0);
ft2.setToValue(1);
ft2.play();
}
}});
}
void saveFile(File save)
{
FileOutputStream fos=null;
try{
fos = new FileOutputStream(save);
}
catch (FileNotFoundException e){
e.printStackTrace();
}
try{
fos.close();
} catch (IOException e){ e.printStackTrace();
}
}
}
当打开＆＃39>时，控制台会抛出此错误。按钮运行：

答案 0 :(得分：1)
显然，您从文件中读到的文字会尝试通过＆＃39;，＆＃39;并不包含您期望的硬编码数组索引的结构：
getrecordsarray.add(new Getrecord(g[0], Double.parseDouble(g[1]), Double.parseDouble(g[2]), Double.parseDouble(g[3]), Double.parseDouble(g[4]), Double.parseDouble(g[5]), Double.parseDouble(g[6]), Double.parseDouble(g[7])));
