import java.sql.Statement;

public class Database{
public Connection conn = null;
private String dbName = null;

public Database(){
}

public Database(String dbName, String dataSourceName){
this.dbName = dbName;
try{
      class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
       this.conn = DriverManager.getConnection(dataSourceName)
      System.out.println("Connected Successfully");
     }

catch(ClassNotFoundException e){
e.printStackTrace();
}

catch(SQLException e){
e.printStackTrace();
}
}

Step 4:  Execute it from Main Method:

import java.sql.*;

public class Main{

public static void main(String[] args)
{
