Assign variable

Question

What is the difference:
if I write
public class Test
static final String ImeDat="joga1.gif";
public static void main (String args[]) throws Exception
try {
System.out.print("Connecting to the Database. Please wait..");
//Load the Oracle JDBC Driver and register it.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database:
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@", "scott", "tiger");....
I get NO ERROR message during compiling
BUT
public class Test
static final Connection conn;
static final String ImeDat="joga1.gif";
public static void main (String args[]) throws Exception
try {
System.out.print("Connecting to the Database. Please wait..");
//Load the Oracle JDBC Driver and register it.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Connect to the database:
conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@", "scott", "tiger");...
I always get
C:\xsu>javac Test.java
Test.java:41: Can't make a static reference to nonstatic variable conn in class
Test.
conn =

1 error
C:\xsu>javac Test.java
Test.java:17: Blank final variable 'conn' may not have been initialized. It must
be assigned a value in an initializer, or in every constructor.

In the inspector for your "on" button, set the audio stream to whatever stream you want. for the "off" button set it to the other stream. dont forget to assign the action you want the button to take (ie - jump to main menu:play.) You can also do this with a script as well
