help

When i try to compile this:

public static Rand searchCount (int[] x) 
{
    int a ; 
    int b ;

...

        for (int l= 0; l<x.length; l++) 
        {
            if (x[l] == 0) 
            a++ ;
            else if (x[l] == 1) 
            b++ ;
        }

...

I get these errors:

Rand.java:72: variable a might not have been initialized
                a++ ;
                ^
Rand.java:74: variable b might not have been initialized
                b++ ;
                ^
2 errors

it seems to me that i initialized them at the top of the method. Whats going wrong?
