Thread: Updating a specific value in a linked list

I create and populate someLinkedList with '*' characters as soon as a gameLinkedList object is created, so my class is something like

private int size;
public class gameLinkedList{
private CharNode game;
public gameLinkedList(String someWord){
size=someWord.length();
for(int i=0;i<size;i++){CharNode aNode = new CharNode('p');
if(CharNode==null){game=aNode;}
else{aNode.setLink(game);game=a;}
}
}
public boolean exists(guess){return someWord.indexOf(guess);}
//take a character, compare it to all characters
public boolean play(char c){
CharNode newNode=new CharNode(guess);
if(exists(guess)){
//insert newNode into aNode at the position corresponding to the guess character's //position in someWord
}}
}
