Java connect to Access Database

javams-accessodbcrelational-database

Im trying to be able to access data from an access database.

I have configured the odbc driver for *.mdb and *.accdb files under the ODBC Administrator. I am using windows 7 through parallels(not sure if that makes a difference)

When i run the program I get the following error:

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no     default driver specified
at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6964)
at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7121)
at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(JdbcOdbc.java:3080)

at java.sql.DriverManager.getConnection(DriverManager.java:571)
at java.sql.DriverManager.getConnection(DriverManager.java:215)
at DataAccess.main(DataAccess.java:13)

start code:

import java.sql.*;

public class DataAccess 
{
public static void main(String[] args)
{
    try
    {
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        String connURL = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ="+"C:\\Users\\alexmac\\Desktop\\OASDatabase\\OAS_Database";

            String table = "Student";        
            Connection conn = DriverManager.getConnection(connURL, "", "");
        Statement s = conn.createStatement();

              // Fetch table
        String selTable = "SELECT * FROM " + table;
        s.execute(selTable);
        ResultSet rs = s.getResultSet();
        while((rs!=null) && (rs.next()))
        {
            System.out.println(rs.getString(1) + " : " + rs.getString(2));
        }

        // close and cleanup
        s.close();
        conn.close();
    }
    catch(Exception ex)
    {
        ex.printStackTrace();
    }
}
}

In addition to the double-extension problem (.accdb.accdb) mentioned in the comment above, your code won't work because the driver name you specified...

DRIVER={Microsoft Access Driver (*.accdb)}

...is incorrect. There is no ODBC driver with that name. 32-bit applications that want to open an older .mdb database file can use

Driver={Microsoft Access Driver (*.mdb)}

To open an .mdb file from a 64-bit application, or to open an .accdb file from any application, you need to use

Driver={Microsoft Access Driver (*.mdb, *.accdb)}

Java – What are the differences between a HashMap and a Hashtable in Java

There are several differences between HashMap and Hashtable in Java:

Hashtable is synchronized, whereas HashMap is not. This makes HashMap better for non-threaded applications, as unsynchronized Objects typically perform better than synchronized ones.
Hashtable does not allow null keys or values. HashMap allows one null key and any number of null values.
One of HashMap's subclasses is LinkedHashMap, so in the event that you'd want predictable iteration order (which is insertion order by default), you could easily swap out the HashMap for a LinkedHashMap. This wouldn't be as easy if you were using Hashtable.

Since synchronization is not an issue for you, I'd recommend HashMap. If synchronization becomes an issue, you may also look at ConcurrentHashMap.

Java – Is Java “pass-by-reference” or “pass-by-value”

Java is always pass-by-value. Unfortunately, when we deal with objects we are really dealing with object-handles called references which are passed-by-value as well. This terminology and semantics easily confuse many beginners.

It goes like this:

public static void main(String[] args) {
    Dog aDog = new Dog("Max");
    Dog oldDog = aDog;

    // we pass the object to foo
    foo(aDog);
    // aDog variable is still pointing to the "Max" dog when foo(...) returns
    aDog.getName().equals("Max"); // true
    aDog.getName().equals("Fifi"); // false
    aDog == oldDog; // true
}

public static void foo(Dog d) {
    d.getName().equals("Max"); // true
    // change d inside of foo() to point to a new Dog instance "Fifi"
    d = new Dog("Fifi");
    d.getName().equals("Fifi"); // true
}

In the example above aDog.getName() will still return "Max". The value aDog within main is not changed in the function foo with the Dog "Fifi" as the object reference is passed by value. If it were passed by reference, then the aDog.getName() in main would return "Fifi" after the call to foo.

Likewise:

public static void main(String[] args) {
    Dog aDog = new Dog("Max");
    Dog oldDog = aDog;

    foo(aDog);
    // when foo(...) returns, the name of the dog has been changed to "Fifi"
    aDog.getName().equals("Fifi"); // true
    // but it is still the same dog:
    aDog == oldDog; // true
}

public static void foo(Dog d) {
    d.getName().equals("Max"); // true
    // this changes the name of d to be "Fifi"
    d.setName("Fifi");
}

In the above example, Fifi is the dog's name after call to foo(aDog) because the object's name was set inside of foo(...). Any operations that foo performs on d are such that, for all practical purposes, they are performed on aDog, but it is not possible to change the value of the variable aDog itself.

For more information on pass by reference and pass by value, consult the following SO answer: https://stackoverflow.com/a/430958/6005228. This explains more thoroughly the semantics and history behind the two and also explains why Java and many other modern languages appear to do both in certain cases.
