Java connect with JDBC to Postgres - SQLException

Iam tryig to connect to a Postgres Database. Iam really new to that and have read a post in the forum. But I didn't manage it.
public void connect() {
//Connection con = null;
try {
Class.forName("org.postgresql.Driver");
Properties props = new Properties();
props.setProperty("user", user);
props.setProperty("password", password);
props.setProperty("ssl","true");
Connection conn = DriverManager.getConnection(url, props);
//String url = "jdbc:postgresql://localhost/test?user=fred&password=secret&ssl=true";
//Connection conn = DriverManager.getConnection(url);
System.out.println("Erfolgreich verbunden!");
}
catch (Exception e){
e.printStackTrace();
System.err.println(e.getClass().getName()+": "+e.getMessage());
System.exit(0);
}
}
EDIT:
I updated my Code.
The database is deployed to heroku.
It throws the error:
java.sql.SQLException: No suitable driver found for jdbc:postgres://vuqmbekwlgohkw:******

java.sql.SQLException: No suitable driver found for jdbc:postgres://vuqmbekwlgohkw:***************

I believe that your problem is that your connection URL is malformed.
When DriverManager.getConnection throws SQLException, the message includes the exact url value passed to the function. In your case, that looks like jdbc:postgres://vuqmbekwlgohkw:******.
But obviously that is not the URL you are using. You have replaced part of the URL with asterisks. That suggests that you think the format of the URL is:
jdbc:postgres://username:password#host:port/dbname
which seems to be what Heroku provides in the DATABASE_URL environment variable. You are using asterisks to prevent us from seeing the password.
However, it looks like the PostgreSQL JDBC driver does not accept URLs in this format. When I tried, I also got the "No suitable driver" error. According to the documentation, the format of the URL is:
jdbc:postgres://host:port/database
Some parts are optional, but the driver does not appear to support putting the user name or password in the URL.
I was able to connect to an AWS PostgreSQL instance by using the URL format described in the documentation and using the connection properties to set the user name and password.

You said you are new so I'm gonna start with the painfully obvious, do you have the driver on your classpath?
it's a jar you add to your project that you can download from https://jdbc.postgresql.org/
Otherwise I have an example of the url that worked for me, except I was not exactly using jdbc, it was a spring-boot project:
jdbc:postgresql://ec2-174-99-88-88.compute-1.amazonaws.com:5432/asdfasdfsadf?sslmode=require
There is no port number in your commented URL and not all parameters might be supported, like Willis pointed out.

No suitable driver found for jdbc:sqlserver:

I know this has been asked a hundred times and I think I have read all the posts and tried every variation of the solutions. I'm using NetBeans and new to it. I'm sure I'm just missing some small step because it seems like its just not seeing the driver that I added to the library. This is the first time I have tried to connect to a database so please be gentle.
try
{
String host = "jdbc:sqlserver://Server:1433;Database";
String uName = "User";
String uPass = "Password";
Connection con = DriverManager.getConnection(host,uName,uPass);
System.out.println("Your are connected to SQLServer 2014");
}
catch (SQLException err)
{
System.out.println(err.getMessage());
}

You forgot to register the jdbc driver class.
Call
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
before calling Connection con = DriverManager.getConnection(host,uName,uPass);.
It will resolve the issue.
UPDATE
In documentation for new jdbc drivers it is declared that this step is not necessary. But in practical work, I have found that this step is required even for new drivers, otherwise you will get "No suitable driver found" error. This error occurs sometimes, for example it does not occur when you are making and running a console jar-application, but occurs when you have created and deployed a web-application.
So, I advise to register the jdbc driver class before getting the database connection via DriverManager.getConnection() call.

Java: database connection. Where is my mistake?

Hy!
I really need your help. I'm trying to connect a database to a java program. This is my first time, so I have no idea what i'm doing.
My sql server: Sql server
I want to connect the Test database to the java program.
I tried the following code:
Class.forName("oracle.jdbc.driver.OracleDriver");
Connection conn = null;
conn = DriverManager.getConnection("jdbc:mysql:WIN2CNG9\\SQLEXPRESS:3306/Test", "win2cng9\\kmim1437", "");
conn.close();
The error:
Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:mysql:WIN2CNG9\SQLEXPRESS:3306/Test
at java.sql.DriverManager.getConnection(DriverManager.java:689)
at java.sql.DriverManager.getConnection(DriverManager.java:247)
at javaapplication42.JavaApplication42.main(JavaApplication42.java:24)
Java Result: 1
What is my mistake?
Thank you for any help.

Class.forName("oracle.jdbc.driver.OracleDriver");
DriverManager.getConnection("jdbc:mysql:
Why your use Oracle driver with mysql database? Use following code:
Class.forName("com.mysql.jdbc.Driver");
Connection conn = null;
conn = DriverManager.getConnection("jdbc:mysql:WIN2CNG9\\SQLEXPRESS:3306/Test", "win2cng9\\kmim1437", "");
conn.close();

No suitable driver found for jJDBC

I am getting this exception
No suitable driver found for
jdbc:derby://localhost:1527/Test [saad on SAAD]
Connection con=DriverManager.getConnection("jdbc:derby://localhost:1527/Test [saad on SAAD]");

Before this
Connection con=DriverManager.getConnection("jdbc:derby://localhost:1527/Test [saad on SAAD]", dbusername, dbpassword); // default username = "root" , default password = ""
You have to write this
Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
But first of all, you must import the driver jar for apache derby

Connecting to mySQL Database with Java

In my program I am trying to connect to a mySQL database. This program is written in Java.
I am trying to connect to my database with this code here (? is a place holder b/c I dont know what does there.)
Connection conn = DriverManager.getConnection("jdbc:sqlite:*?*");
I need someone to help me replace the ? to connect to my database. I know the IP (Just call it ***.***.*** for security reasons, the port which is 3306 and the database is called devicede_Test).
Please help me replace the ? with the correct string with the info above, thanks!

Try this
Connection conn = DriverManager.getConnection("jdbc:mysql://***.***.***:3306/dbname");

Try this:
String url = "jdbc:mysql://localhost:3306/mysql";
Connection con = DriverManager.getConnection(url,"root", "");

SQLIte is not the right driver here. Use:
Connection conn = DriverManager.getConnection("jdbc:mysql://**.***.***.***/devicede_Test", user, pass);

The JDBC URL format for MySQL Connector/J is as follows, with items in square brackets ([, ]) being optional:
jdbc:mysql://[host][,failoverhost...][:port]/[database] »
[?propertyName1][=propertyValue1][&propertyName2][=propertyValue2]...
Here is a sample connection URL:
jdbc:mysql://localhost:3306/sakila?profileSQL=true
