我有一个循环,在循环结束时a String[]被添加到ArrayList(在类中声明而不是方法)并且在循环的开头说String[]清除了它的内容:

String[] a = new String[2];
while(true){
  a[0] = "";
  a[1] = "";
  -----some code----

(that adds to a[0] and a[1])

  -----some code----
  //lets call our ArrayList list
  list.add(a);
}

因此,列表中存储的内容通常是空的String.我认为这是因为java进入下一步的速度太快但我不确定,请问有什么帮助吗？这是我的所有代码:

static ArrayList<String[]> Names = new ArrayList<String[]>();
public static void read(BufferedReader stream){
        String[] aux = new String[2];
        char it = 2;

    try{
        while(it != (char) -1){
            aux[0] = "";
            aux[1] = "";
            it = (char) stream.read();

            while(Character.isLetter(it)){
                aux[0] += it;
                it = …
