Write a java program which illustrates the concept of Batch processing?

import java.sql.*;
class BatchProConcept {
 public static void main(String[] args) throws Exception {
   System.out.println("DRIVERS LOADED...");
   Connection con = DriverManager.getConnection("jdbc:odbc:oradsn", "scott", "tiger");
   System.out.println("CONNECTION ESTABLISHED...");
   Statement st = con.createStatement();
   st.addBatch("insert into student values (3, 'j2ee')");
   st.addBatch("delete from student where sno=1");
   st.addBatch("update student set sname='java' where sno=2");
   int res[] = st.executeBatch();
   for (int i = 0; i < res.length; i++) {
    System.out.println("NUMBER OF ROWS EFFECTED : " + res[i]);
  } // main
}   // BatchProConcept
