Modularize the java code

Question

Hello All,
I am working on a Java project in eclipse which has the following structure:
package
    |---Trie.java
    |---TrieImpl.java
    |---TrieNode.javaThe main class and the operations on the Trie are methods in 'TrieImpl.java'
In short, the TrieImpl.java file is as:
import.....
public class TrieImpl<T> implements Trie<T>
    public boolean delete(String key) {
    public void insert(String key, T value) {
   public void search(String query, int distance) {
   search(root,query,distance,qPos,weight,result,found);
   private void search(TrieNode<T> node, String Q, int D, int qIndex, int W, StringBuilder result, boolean found) {
   while (found == false && qIndex < Q.length() && W <= D ) {
   do something
   search(n, Q, D, qIndex, W, result, found); // recursive search
   public void static main {
       TrieImpl<String> tree = new TrieImpl<String>();
       ......get the query and distance from the user......
       tree.search(query,distance);
  }I would like to use Global variables like the boolean variable found in the search function.
for e.g. here are some variables I would like to be global
boolean found
int distance
int qIndex
String Q (the original query string)
StringBuilder result
So that when I set the found to true in any on the search recursions, I can exit the search stack.
The problem right now is that since I am passing the 'found' value at every recursion, each stack has a different boolean value for found.
Some suggestions I googled instructed to create a global class and access the variables with the class identifier.
How can I do that here?
Thanks in advance.

The problem right now is that since I am passing the 'found' value at every recursion, each stack has a different boolean value for found.Why doesn't your method just return a bool to indicate the result?
