How load a txt file using ClassLoader?

I have the following code:

 public class App {
   public static void main(String[] args) {
     System.out.println(App.class.getClassLoader().getResource("test.properties"));
     System.out.println(App.class.getClassLoader().getResource("test.txt"));
     System.out.println(App.class.getClassLoader().getResourceAsStream("test.properties"));
     System.out.println(App.class.getClassLoader().getResourceAsStream("test.txt"));
     System.out.println(App.class.getResourceAsStream("test.properties"));
     System.out.println(App.class.getResourceAsStream("test.txt"));
   }
 }

This code gives the following output:

file:/C:/../test.properties 
null 
java.io.BufferedInputStream@18e2b22 
null 
java.io.BufferedInputStream@1cb1c5fa 
null

Why does ClassLoader refuses to load .txt file?

Updated:

I'm sure that both of my files in the classpath. Classpath is set to /src and both files are in this directory.

You will need to ensure that any file you want to load using ClassLoader is included in your classpath. Normally resources like that are stored in /src/main/resources which is then included in the classpath.

If you're using Eclipse you can right click on the project in the explorer and go to Properties -> Java Build Path -> Source (Tab) -> Add Folder... (Button) and add the folder structure in there.

Most likely your txt file is not on the classpath
