java - 为什么我的语句不能将字符串解析为整数？

Question

我正在尝试将字符串解析为整数，但我得到了不兼容的类型。我的计数器用于记录文件中的记录数量，程序可以附加到文件并从中读取。现在我想对其进行排序并将其写回文件。我怎样才能执行这个任务？此处未声明的变量将在全局范围内声明。

public static void sort_addresses() throws IOException
{
 String tnumber;
 String tname;
 String tnrooms;
 int[] tmprooms;
 int[] tmprooms1;
 int j;
 for (int i = 0; i < counter; i++)
 {
    for(j = 1; j < (counter-1); j++)
    //while (street_name[counter] != null)
    {
        tmprooms = Integer.parseInt (number_rooms[counter]); 
        tmprooms1 = Integer.parseInt (number_rooms[counter+1]); 
        if (tmprooms[i] > tmprooms1[i+1])
        {
            tnumber = street_number[counter];
            tname =  street_name[counter];
            tnrooms = number_rooms[counter];
            street_number[counter] = street_number[counter +1];
            street_name[counter] = street_name[counter+1];
            number_rooms[counter] = number_rooms[counter+1];
            number_rooms[counter+1] = tnumber ;
            street_name[counter+1] = tname;
            number_rooms[counter+1] = tnrooms;
            System.out.println(street_number[i]+"\t"+street_name[i]
                +"\t"+number_rooms[i]);
        }
    }

Answer 1

声明:

  int[] tmprooms;
  int[] tmprooms1;

作为

  int tmprooms;
  int tmprooms1;

Integer#parseInt()返回 int ，而不是 int[] 。
