Main.java
ApplicationContext ac = new ClassPathXmlApplicationContext("context.xml", Main.class):-ApplicationContext is the interface that is used to  provide Bean factory methods for accessing application components. Here we Creates an instance of this interface to accesscontext.xml and Main.java.
DataSource source = (DataSource) ac.getBean("dataSource"):-Data source is an Interface which provides a way for connecting to the physical data source. Here we created datasource for making connection to our xml document in which we have declared the bean.
jt.batchUpdate(new String[]{"update employee set departement = 'Finance#'", "delete from employee where EmployeeId =31" }):-With the use of this method we are executing two SQLquerysimultaneously. This method executes multiple Sql updates on a single JDBC statement.
import javax.sql.DataSource;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;
class Main {
    public static void main(String args[]) {
        try {
            ApplicationContext ac = new

            DataSource source = (DataSource) ac.getBean("dataSource");
            JdbcTemplate jt = new JdbcTemplate(source);
            jt.batchUpdate(new String[]{"update employee set departement = 'Finance#'",

            System.out.println("Data updated successfully");
        } catch (Exception e) {
            e.printStackTrace();
                    }

Output of the program
Data updated successfully
BUILD SUCCESSFUL (total time: 2 seconds)
