Hoping the current project is readable, tried my best to edit it. Anyhow. How can I pull the values from DisplaySB arrays and place them into the UserBooking arrays? I need to do this to total the amount of seats left for the coach. The errors are within the last snippet, specifically on the last two arrays.
希望当前项目可读，尽我所能编辑它。无论如何。如何从DisplaySB数组中提取值并将它们放入UserBooking数组中？我需要这样做才能累计为教练留下的座位数。错误在最后一个片段内，特别是在最后两个数组上。

Declare the DisplaySb-arrays as class variables with getters and setters and fetch them from UserBooking like
使用getter和setter将DisplaySb数组声明为类变量，并从UserBooking中获取它们
ArrayList<String> fb = new MyClassNameWhereDisplaySBLives().getFBArray();
#2

public class MyClass{
//class variables - outside method body, so every method "knows" them
private ArrayList<String> fb = new ArrayList<>();
public void displaySB() throws IOException{
//fill fb with values
fb.add("1"); //ID
//...
}
public void userBooking(){
//retrieve data from fb
fb.get(0);
}
