Hi All
I am beginner in Java and this is my first post.
Please could you help me with this .
I need to implement a basic singly-linked list structure as a class. also it should allow
addition and deletion of single element in the linked list at a specified position i. we can assume each element is represented using the int primitive data type.
I would be very great full if you point me some sample programs like i described
Do you have any code that you are having problems with?
If so, post the code and ask questions about your problems.
How can I get a link list to print out in an array? Any ideas?
Can you explain what you are trying to do?
"print out in an array" makes no sense to me.
Do you want to extract nodes from a linked list and store them in an array?
Sorry to be a pain,
yeap, extract nodes from a linked list and store them in an array
Use the linked list class's methods to get the nodes one by one and assign them to an array slot as you get them.
is that ok if PM you my code?
I don't do any work out of the public. If you want help you'll have to post code here with your questions.
If you can isolate a particular problem to a small program that will help.
no thats fine, just didn't wanted to make a mess ))
public void insert(int x){
if(start==null){
start=new Node(x,start);
}
if(start!=null){
Node temp=start;
while(temp.next!=null){
temp=temp.next;
}
temp.next=new Node(x);
This is what I'm using to insert a node,
But how do I insert a strand
By strand do you mean another linked list?Quote:
But how do I insert a strand
Change the links to point to the front of the new list and change the end of the new list to be back into the original list.
Draw it on a piece of paper if you need to see what I'm talking about.
no, that is a string,
Please explain you question. I don't understand what you are asking.
I need to implement, crossover phenomenon. given 2 dan strands and an index i, d strands should cross-over so that d 1st i nucleotides of the 1st strand r unchanged, but d remainder is replaced with d nucleotides from d position i+1 go d 2nd strand. equally, d first i nucleotides of d 2nd strand should be unchanged, but d remainder of the 2nd strand. for ex, if d initial strands r:

thank you very much and I do apologise for my unclear questions
What is a String?
thats my full question, is that make sense :confused:
You'll have to translate from the jargon you used in post#13 to something related to java programming.
what u mean jargonQuote:

cossover phenomenon. given 2 dan strands
d nucleotides from d position i+1 go d 2nd strand.
d first i nucleotides of d 2nd strand
None of that has any meaing for me.
#3 in post#18
i know what does jargon means i asked which words unclear
If you want anyone to test your code, you need to post a complete program that compiles and executes.Quote:
please tell me if there is anything wrong with my code
A small program that shows the problem without any other stuff that is not related to the problem.

I'll let you do the translating to programming language from your project's terminology(jargon)
Do you have a java programming question?
sorry Norm, that is exactly how on paperQuote:
