Transaction using java mysql

The transaction is a set of Sql statement that can be executed as a single unit.the transaction is complete only when all the sql statements in a transaction excute successfully.if any one of the sql statement in the transaction fails the entire transaction is rolled back.

paste the code inside the main method

import java.sql.*;

public class Transaction 
{
 public static void main(String args[])
 {
  Connection con;
  PreparedStatement ps1;
   try {
   Class.forName("com.mysql.jdbc.Driver");
   con = DriverManager.getConnection("jdbc:mysql://localhost/vmproducts","root","");
    
    con.setAutoCommit(false);
    
    ps1 = con.prepareStatement("insert into product(pname,price,qty)values(?,?,?)");
    ps1.setString(1,"Mouse");
    ps1.setInt(2,15000);
    ps1.setInt(3,100);
    int first = ps1.executeUpdate();
    System.out.println("First Row Inserted but not commited");
    
    ps1 = con.prepareStatement("insert into product(pname,price,qty)values(?,?,?)");
    ps1.setString(1,"Keyborad");
