Good afternoon, I can not understand why I stopped loading the resource I work in eclipse, the composition of the project and the location of the file did not change it in the resources package

enter image description here ,

but suddenly it became an error.

Java.lang.NullPointerException in thread "java.io.DataInputStream.read (DataInputStream.java:100) at com4j_example.Main.main (Main.java:68)

I use this design for download.

InputStream in = Main.class.getResourceAsStream("date.txt"); System.out.println(in); DataInputStream din = new DataInputStream(in); FileOutputStream outF = new FileOutputStream("C://Users/Desktop/resources/date.txt//"); byte[] buffer = new byte[1024]; int count = 0; while ((count=din.read(buffer)) != -1){ outF.write(buffer,0,count); } outF.flush(); outF.close();
  • What ide? What jar will she build? Open it in the archiver (jar is actually a normal zip) and see which folder the resource got into. May need to do so Main.class.getResourceAsStream ("resources / com4j_example / date / date.txt"); - Sergey

Everything was decided by adding the resources folder in the bin package in the project, and then in the package to the project classes. The path turned out such

bin / "package name" /resources/date.txt
