[Karthikeyan Ravindran]

I am getteing an error as LinkedList does not take parameters

LinkedList <Integer>queue = new LinkedList<Integer>();
///////////////////////////////////////below is the code

import java.util.*;

public class ListQueueDemo {
public static void main(String args[]) {
int numbers[]={34, 22,10,60,30};
List <Integer>list = new ArrayList<Integer>();
try{
for(int i=0; i<5; i++){
list.add(numbers[i]);
}
System.out.println("the List is: ");
System.out.println(list);
LinkedList <Integer>queue = new LinkedList<Integer>();
for(int i=0; i<5; i++){
queue.addFirst(numbers[i]);
}
System.out.println("The Oueue is: ");
System.out.println(queue);
queue.removeLast();
System.out.println("After removing last element the queue is: "+ queue);

}
catch(Exception e){}
}
}

Your code works fine for me.what error messages are you getting?can you post it?

[Ulf Dittmer]

catch(Exception e){}

That's generally not such a good idea. You should at least print out a message that an exception occurred.

Are you using Java 5 or Java 6? Generics was only introduced for Java 5. You might be using an older version.

I am using java5 when i am using it with set its taking but with linkedlist its not taking.. i am getting error as

type linkedlist does not take parameters

Sounds more like you're using Java 1.4 compatibility. I've only seen this error when copying code from a Java 5 project to a Java 1.4 project in Eclipse.

[camilo lopes]

can you use generics only java 5.

Only Java 5 or more recent (Java 6).

Is there any chance you have a LinkedList class you have written yourself?

[Karthikeyan Ravindran]

I am not using any userdefined linkedlist class..
