private static ObjectPool pool = new ObjectPool(100);
private int x, y;
public static PooledPoint create(int x, int y) {
PooledPoint p = (PooledPoint) pool.allocate();
if (p == null)
p = new PooledPoint();
p.init(x, y);
return p;
}
private PooledPoint() {}
private void init(int x, int y) {
this.x = x;
this.y = y;
}
public void free() {
this.finalize();
pool.free(this);
