Private String database_user_name = "postgres" Private String database_connection_string = "jdbc:postgresql://localhost:5432/postgres" Sample Java Code package netbeanstopostgres In the sample code below, we need to first define three variables:ĭatabase_connection_string: the JDBC database connection URL, so that the code knows where it needs to connect.ĭatabase_user_name, database_user_password: the database username and password for the connection.īy using the Connection connect() code we are defining the connection object, which will connect to the database and after the successful connectivity will print the successful connection message. You will get the message "You are successfully connected to the PostgreSQL database server." after the successful connection with the database.

Change the database server hostname, database port, database port, and database name as per your environment, or else you will get an error at the time of the connection. With JDBC, a database is represented by a URL (Uniform Resource Locator). In the sample code below, I am using the JDBC connection string for the connection.
