Txtfile搜索不起作用

Question

好吧,我已经输入了一些文本文件的记录,我可以写入和读取此文件,但我现在正在尝试搜索此文本文件,并遇到了问题.

package assignmentnew;

// Import io so we can use file objects
import java.io.*;
import java.util.Scanner;

public class SearchProp {
    public void Search() throws FileNotFoundException {
        try {
            String details, input, id, line;
            int count;
            Scanner user = new Scanner(System.in);
            System.out.println();
            System.out.println();
            System.out.println("Please enter your housenumber: ");
            input = user.next();
            Scanner housenumber = new Scanner(new File("writeto.txt"));
            while (housenumber.hasNext())
            {
                id = housenumber.next();
                line = housenumber.nextLine();
                if (input.equals(id))
                {
                    System.out.println("House number is: "  + id + "and" + line);
                    break;
                }
                if(!housenumber.hasNext()) {
                    System.out.println("no house with this number");
                }
            }
        }
        catch(IOException e)
        {
            System.out.print("File failure");
        }
    }
}

无论我输入什么价值,我都被告知文件中没有门牌号码,但显然是,任何想法？

扫描程序的默认分隔符是空格,而不是,.
