How do I get path of files such as PDF, image, PPT from a file chooser in android studio (JAVA)?

//case 1: //Result of Log.i("km",path); /content:/com.android.externalstorage.documents/document/primary%3ADCIM%2Fimages.jpeg //what is primary%3ADCIM%2? //Why i'm not getting proper path like documents/document/primary/DCIM/images.jpeg

//case 2:
// DocumentFile d = DocumentFile.fromSingleUri(this, uri);
// Log.i("fe", "path: " + d.getUri().getPath());

//Result
/document/primary:DCIM/images.jpeg
