Java compiler: "cannot find symbol method getResult()"

Hello

My Java compiler is giving me a weird error... of course I know the problem is me, but I can't figure it out!

The details of the code aren't really important, as the problem is related to the getResult() method only, but just in case: I have two threads searching through an array looking for the largest number. I have a method getResult() which returns the result of the search. One of the threads searches the first half of the array, the other searches the second half.

/*
 * Find the maximum element in a large array
 * Two threads
 *
 */
 
 import java.util.*;
 
 class Search extends Thread {
 	
 	private int largeArray[];
 	private int start;
 	private int end;
 	private int biggest;
 		 
 	Search(int largeArray[],int start,int end) {
 		this.largeArray = largeArray;
 		this.start = start;
 		this.end = end;
 	}
 	
 	public void run() {
 		// navigate through each element in the array starting at start
 		biggest = largeArray[start];	
 		for(int x = (start+1); x <= end; x++)
 			if (biggest<largeArray[x])
 				biggest = largeArray[x];
 		// biggest should now contain the biggest number
 	}
 	
 	public int getResult() {
 		return biggest;
 	}
 	
 }
 
 class Question2 {
 	public static void main(String[] args) {
 		
 		System.out.print("How many elements in the array? ");
 		Scanner in = new Scanner(System.in);
 		int x = in.nextInt();
 		
 		int largeArray[] = new int[x];
 		
 		for (int count = 0; count < largeArray.length; count++) {
 			largeArray[count] = (int)(Math.random()*x);
 		}
 		
 		int split = x/2;
 		
 		Thread t1 = new Search(largeArray,0,split-1);
 		Thread t2 = new Search(largeArray,split,x-1);
 		
 		t1.start();
 		t2.start();
 		
 		try {
 			t1.join();
 			t2.join();
 		} catch (InterruptedException e) {}
 		
 		if (t1.getResult()>t2.getResult())
 			System.out.println("The biggest number is " + t1.getResult());
 		else 
 			System.out.println("The biggest number is " + t2.getResult());
 		// catches if they are equal too
 	}
 }

So, it's pretty simple, but the compiler doesn't like the getResult() method.

Can any of you figure out why?

Thanks very much in advance.
