Through this example, we may see how to use JDBC to connect to Mysql database and perform table lookup operations.
Start by creating a test database in Mysql:

Source Code

package com.beginner.examples;

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

public class JDBCConnectMySql {

	public static void main(String[] args) {

		try {

			// The load driver
			Class.forName("org.gjt.mm.mysql.Driver");

			// The url of the database
			String url = "jdbc:mysql://127.0.0.1:3306/test?useSSL=false";

			// Get the Connection object
			Connection connection = DriverManager.getConnection(url, "root",
					"root");
			// Create an object to execute the SQL statement
			Statement statement = connection.createStatement();

			// Execute SQL statement :show table,the execution results are
			// stored in a ResultSet
			ResultSet tables = statement.executeQuery("show tables");
			
			System.out.println("All the tables:");
			
			//Iterative ResultSet
			while (tables.next()) {
				
				String tableString = tables.getString("Tables_in_test");
				
				System.out.println(tableString);
			}

			//Close the connection
			connection.close();


		} catch (Exception e) {

			e.printStackTrace();
		}

	}

}

Output:

All the tables:
table_1
table_2
table_3
