Write a java program which illustrates the concept of procedure?

create or replace procedure StuPro
(no in number, name in varchar2, loc1 out varchar2)
as
begin
select dname, loc into name, loc1 from dept
where deptno=no;
insert int abc values (no, name, loc1);
end;


import java.sql.*;
import java.io.*;
class ProConcept {
 public static void main(String[] args) {
   try {
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    System.out.println("DRIVERS LOADED...");
    Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:
     BudDinu ","scott ","tiger ");
     DataInputStream dis = new DataInputStream(System.in); 
     System.out.println("ENTER DEPARTMENT NUMBER : ");
     String s1 = dis.readLine(); 
     int n1 = Integer.parseInt(s1);
     CallableStatement cs = con.prepareCall("{call StuPro (?,?,?)}"); 
     cs.setInt(1, n1); 
     cs.registerOutParameter(2, Types.VARCHAR);
     cs.registerOutParameter(3, Types.VARCHAR); 
     cs.execute(); 
     String res = cs.getString(2); 
     String res1 = cs.getString(3); 
     System.out.println("DEPARTMENT NAME : " + res); 
     System.out.println("DEPARTMENT LOCATION : " + res1);
    } catch (Exception e) {
     System.out.println(e);
    }
   } // main
  } // ProConcept
