java.lang.NoClassDefFoundError

Imma new java user :confused::confused:
i don't know what's the problem on my code

Code java:

---

public class Main {
	public void queueExample() {
 
		Queue queue = new LinkedList();
 
		queue.add("item1");
		queue.add("item2");
		queue.offer("item3");
		queue.offer("item4");
 
		System.out.println("remove: " + queue.remove());
		System.out.println("element: " + queue.element());
		System.out.println("poll: " + queue.poll());
		System.out.println("peek: " + queue.peek());
	}
 
	public static void main (String [] args) {
		new Main() queueExample();
	}
}

---

and the output of this code is

java.lang.NoClassDefFoundError: Main
Exception in thread "main"
Process completed.
:confused::confused::confused:

I'm pretty sure you're just missing a period between Main() and queueExample(). Although I don't see how that would result in the Exception you're talking about.

what about this one sir

Code Java:

---

 import java.util.LinkedList;
import java.util.Queue;
 
/**
*
* @author javadb.com
*/
public class Main {
 
/**
* Example method for using a Queue
*/
public void queueExample() {
 
Queue queue = new LinkedList();
 
//Using the add method to add items.
//Should anything go wrong an exception will be thrown.
queue.add("item1");
queue.add("item2");
 
//Using the offer method to add items.
//Should anything go wrong it will just return false
queue.offer("Item3");
queue.offer("Item4");
 
//Removing the first item from the queue.
//If the queue is empty a java.util.NoSuchElementException will be thrown. 
System.out.println("remove: " + queue.remove());
 
//Checking what item is first in line without removing it
//If the queue is empty a java.util.NoSuchElementException will be thrown. 
System.out.println("element: " + queue.element());
 
//Removing the first item from the queue.
//If the queue is empty the method just returns false. 
System.out.println("poll: " + queue.poll());
 
//Checking what item is first in line without removing it
//If the queue is empty a null value will be returned. 
System.out.println("peek: " + queue.peek());
 
}
 
 
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new Main().queueExample();
}
}

i tried this code but it didn't run. :D

For the sake of everyone's sanity, I urge you to keep each problem in its own Thread. Please keep the issue with running your code in the Thread you started for it: http://www.javaprogrammingforums.com...ore-error.html

Full disclosure- I'm not a mod. Do what you want, but keep in mind that you should probably be making it easier for people to help you, not harder.

This is quite uninformative as to the problem...does it compile? Are there exceptions?

Ran unchanged for me. Please post how you are attempting to run your code, and any errors.
