Create an object of Connection class and connect to the database.

After that, prepare a MySQL query statement to count number of records available in table named employee, to execute this query, we will create an object of Statement class.

Then, we create an object named smt of Statement class, that will be used to execute query by using executeQuery() method.

Database details:

  • Hostname: localhost
  • Port number: 3306
  • Username: root
  • Password: 123
  • Database name: demo
  • Table name: employees

Java program to count number of records available in MYSQL table using JDBC

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class DisplayAll {
	public static void main(String[] args) {

			//serverhost = localhost, port=3306, username=root, password=123
			Connection cn=DriverManager.getConnection("jdbc:mysql://localhost:3306/demo","root","123");

			Statement smt=cn.createStatement();

			//query to count all records from table employee
			String q="Select COUNT(*) from employees";

			//to execute query
			ResultSet rs=smt.executeQuery(q);

			//to print the resultset on console
		catch(Exception e)

Output (In Console)
