we can help you correct your code, we're not going to code it for you.
Do you know how to work with (Array)Lists and Generics?

if not, and you're indeed a beginner just starting up, leave stuff like this untill you've got a better hang of java programming.

Have you read the API doc for the ArrayList class?
Do any of its methods look like they would "insert" an element into the list?
Have you tried any of the methods to see what they do?
Try writing a small, simple program that creates an ArrayList and add elements to it.

now i have to create dynamic children tree.a single array-list is possible to do this?
for example i have to create this kind of tree

7
/ | \
2 7 12
/ | \ / \ / \
1 2 3 6 8 11 13

here each parent has average of children. here i have three condition such as (consider the child node as x) 1<=x<=5,6<=x<=10,x>=11.here i have three group of children.how can separate this group of children from a single array-list. is it possible or not. if it is possible can you give me a code to insert the children in array-list (with example).
