The path to retrieving resources using ClassLoader

Question

Basically, I want to include my main icon JFramein a JAR file, so no need to download it from an external location.

For this, I was looking for a Java resource system. What I did with Eclipse:

• I created a new folder called res:

  

• I copied the files inside it using Windows Explorer:

  

• I made this folder the original folder:

  

• I wrote this code:

  URL url = ClassLoader.getSystemResource("/res/icona20.ico");
  

But urlthere is null. What have I done wrong?

Answer 1

As already mentioned, you added resas the source folder, so this is the root, not the name, for example src.

URL url = ClassLoader.getSystemResource("icona20.ico");

( ) , /....

:

URL url = Xyz.class.getResource("/icona20.ico");

.png .ico, Java SE.

( .) maven :

/src/main/java/
/src/main/resources/
/src/test/java/
/src/test/resources/

res MS Visual Studio;).
