Hit count: 442
I have a simple linked list. The node contains a string (value) and an int (count).
In the linkedlist when I insert I need to insert the new Node in alphabetical order. If there is a node with the same value in the list, then I simply increment the count of the node.
I think I got my method really screwed up.
public void addToList(Node node){
//check if list is empty, if so insert at head
if(count == 0 ){
head = node;
head.setNext(null);
count++;
}
else{
Node temp = head;
for(int i=0; i<count; i++){
//if value is greater, insert after
if(node.getItem().getValue().compareTo(temp.getItem().getValue()) > 0){
node.setNext(temp.getNext());
temp.setNext(node);
}
//if value is equal just increment the counter
else if(node.getItem().getValue().compareTo(temp.getItem().getValue()) == 0){
temp.getItem().setCount(temp.getItem().getCount() + 1);
}
//else insert before
else{
node.setNext(temp);
}
}
}
}
