    begin
        for i in pi_dept_details.first .. pi_dept_details.last
        loop
            if pi_dept_details.exists(i)  then
               insert into test_dept values ( pi_dept_details(i).dept_id, pi_dept_details(i).dept_name, null);
               l_course_ids:=null;
               for j in pi_dept_details(i).courses.first .. pi_dept_details(i).courses.last
               loop
                    l_course_ids:=l_course_ids||pi_dept_details(i).courses(j).course_id;
                    insert into test_course values ( pi_dept_details(i).courses(j).course_id, pi_dept_details(i).courses(j).course_name);
               End loop;
               update test_dept set course_ids =l_course_ids where dept_id=pi_dept_details(i).dept_id;

No - not in this forum. This forum, as the title says is for SQL Developer and your question has nothing to do with sql developer.
You need to use JDBC to do what you are asking.
Please mark this question ANSWERED and repost it in the JDBC forum.
https://forums.oracle.com/forums/category.jspa?categoryID=288
Before you repost you should review this article that demonstrates how to call an Oracle stored procedure and pass Oracle object types.
http://technology.amis.nl/2008/07/16/oracle-jdbc-passing-a-table-of-custom-object-type-to-a-stored-procedure-implementing-efficient-single-round-trip-data-exchange-part-two-of-an-adf-application-on-a-plsql-api/
And for any of the code and example you don't understand you should review the relevant sections of the JDBC Developer's Guide.
http://docs.oracle.com/cd/B28359_01/java.111/b31224/oraarr.htm#g1072333
If you do repost in the JDBC forum provide your 4 digit Oracle version, your os and JDK versions and the version and name of the JDBC jar file that you are using.
