I don't know if you can change the size at runtime but you can allocate the size at runtime. Try using this code:

class MyClass {
    void myFunction () {
        Scanner s = new Scanner (System.in);
        int myArray [];
        int x;

        System.out.print ("Enter the size of the array: ");
        x = s.nextInt();

        myArray = new int[x];
    }
}

this assigns your array size to be the one entered at run time into x.
