∟jdeprscan - The Java Deprecated API Scanner

∟"jdeprscan jar_file" - Deprecated API of Class File

This section provides a tutorial example on how to use 'jdeprscan' command to scan for deprecated APIs of a given class file.

If you want to find out what deprecated APIs are used in a given class file, you can run the "jdeprscan class_file" command.

First, let's create a new Java program, Deprecated.java: 

import java.rmi.*;
public class Deprecated {
   // deprecated in 8
   SecurityManager sm = new RMISecurityManager();

   // deprecated in 9
   Boolean b2 = new Boolean(true);
}

Compile it as JDK 7 the "--release 7 -Xlint:-options" options: 

herong> javac --release 7 -Xlint:-options Deprecated.java

Now scan the class file for deprecated APIs: 

herong> jdeprscan Deprecated.class
class Deprecated uses deprecated class java/rmi/RMISecurityManager
class Deprecated uses deprecated method java/lang/Boolean::<init>(Z)V

Cool. The "jdeprscan" did find those two statements that use deprecated APIs.
