Question

is it possible for read and work on classes (.class files) generated by java code?

e.g.) CalculateSum.java – > CalculateSum.class
-> Clojure takes CalculateSum.class and embed it in its code?

Answer 1

You just need to make sure the class file is in your classpath.

Here is some example code.

hello.java:

 public class hello {
     public String sayHi() {
         return "hello world";
     }
 }

$ javac hello.java
$ java -cp clojure.jar:./ clojure.main
user=> (import 'hello) ;; Necessary in 1.2.1, but not 1.3.0
user=> (.sayHi (hello.))
"hello world"
