java.io.FileNotFoundException：read.txt（系统找不到指定的文件）

当我尝试运行它时，我总是会收到此错误：

IOException: java.io.FileNotFoundException: read.txt (The system cannot find the file specified)

这是我的代码段：

    try(BufferedReader in = new BufferedReader(new FileReader("read.txt"));
    BufferedWriter out = new BufferedWriter(new FileWriter("write.txt"))){
    String l;

    while((l=in.readLine())!=null)
     out.write(l);
   }
   catch(IOException e){System.out.println("IOException: "+e);}

更多我使用NetBeans 8.0.1。我在此站点上进行了一些类似的查询，并尝试将上述read.txt和src文件夹以及它以及类文件放在其中。但是我仍然收到此错误。有人可以指出我的错误吗？

我刚刚在尝试构建项目时就注意到了这一点。我是新来的，所以无法理解是否与我的问题有关
