Programming :: How To Set Up Global Class In JAVA?

May 10, 2011

I've had to do some code in java, a language I'm very much unfamiliarly with so please excuse my incorrect use of terms. The basic outline of my problem is I create a class object as a local within a swing button function it works fine. If I create it as a global ( with I think I need to do ) within main, then prototype it with the other swing objects at the bottom of the file when it is called it causes a host of problems. I think the easiest way is to show it.

Ubuntu Security :: Malware-gen In Class Files With Latest Java?

Apr 4, 2011

I browse with Firefox and I had been running a pretty vanilla install of Ubuntu 10.4 (with a few things like tomcat and mysql) I supposed the repos kept everything (like java) up to date.

Some time ago I replaced OpenJDK with SunJDK.
java -version is "1.6.0_24"
which java is /usr/bin/java

Yesterday, for the first time, I downloaded and ran an Avast! scan. It complains of "Malware-gen" in several class files in what I think is the java cache. Does anyone know how this could be?

I want to ask how i set Linux class path for mail.jar and mysql-connector.jar. I have set the class path for java with the command.

Code:

when i do java -version it's work fine.

Also if i want to know that what shell i am using how can i find it.Also what is the command for showing class path variables or how can i see my JAVA_HOME class path.Means after setting the class path for above two files how can i see that these files have added.

When i write echo $CLASSPATH or echo $JAVA_HOME it shows nothing no error but again shows the prompt.

One thing more i want to run a java program on Linux it is in a package (named asteriskproject). It consist of 10 java files. I have run this program on windows using netbeans IDE.For this program i need to set my Linux class path for the above mentioned files, and this is my first time that i am running any program on Linux. So i want to ask how can i run my program. Simply put this asteriskproject directory in any folder and run the main file using javac. Is it right way to run the program that consist of package ?

Okay so I'm working on a program here as I'm learning java,I have an array that is initialized with 5 objects that are hard coded. I have made a GUI that takes the input needed and creates an object with those values.I need to add that object to the ArrayList that I have previously made.Okay, so I have three classes, guiclass.java, main.java and gladiator.java Objects are made and defined in "gladiator".Main contains my public static void main section, launches my gui, creates my five hard coded objects, creates my ArrayList and adds my five hard coded objects to the ArrayList.Now, I need to add the object that I generated in the guiSection [action Listener]to the ArrayList that I created in my main class's public static void main string... section. Problem is my arraylist "cannot be resolved" from guiclass.

This will enable me to select a point to the right of any point in the matrix: "Matrix(next[i],j)"

Programming :: Worker Class For Program Coordinator?

Mar 9, 2010

Here's what I'm trying to do: I'm attempting to create a Worker program which is to be called in a Coordinator program. The worker program needs to add two numbers from the argv and return the sum of those numbers. Basically my problem is some sort of syntax and I'm fairly new to this scripting stuff. Here's what I have:

#!/bin/bash
# Worker class for the program Coordinator
int worker(int argc, char *argv[] {
int sum = 0;
sum = atoi(argv[1]) + atoi(argv[2]);
printf("I am child with PID %d", getpid());
printf("sum=%d
", sum);
fprintf(atoi (argv[3]), sum, 4);
exit(sum); }

Here's the errors:

./worker: line 4: `int worker(int argc, char *argv[]'

Programming :: Default Port For UDPWriter Class?

May 9, 2011

This is a really specific question, but maybe someone can help. I'm debugging someone else's code, and they call a UDPWriter and specify an IP address and port, and I'm trying to make sure this multicast traffic goes over a certain port. How can I determine which port the UDP defaults to and change it?

It's confusing to me because I'm not familiar with all the layers the OS sends traffic through before it goes through the interface. Is there maybe some simpler way to tell the OS to send multicast traffic over both interfaces?
