Dificuldade com JDBC

Pessoal, estou aprendendo a programar agora com JAVA, o livro do Deitel. Estou tentando reproduzir o exemplo do livro de JDBC.

import java.sql.Connection;

import java.sql.Statement;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.ResultSetMetaData;

import java.sql.SQLException;

public class JDBC{
	
	static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
	static final String DATABASE_URL = "jdbc:mysql://localhost/t";
	
	public static void main(String[] args) {
		Connection connection = null;
		Statement statement = null;
		
		try {
			Class.forName(JDBC_DRIVER);
			connection = 
					DriverManager.getConnection(DATABASE_URL);
			
			statement = connection.createStatement();
		}	catch(SQLException e) {
			e.printStackTrace();
			System.exit(1);
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
			System.exit(1);
		} finally{
			try {
				statement.close();
				connection.close();
			} catch(Exception e) {
				e.printStackTrace();
				System.exit(1);
			}
		}
	}
}

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
