string natural sorting in Java/Android

I am doing ascending string sorting. And currently, "Route101" would sort ahead of "Route11" because 10 is ahead of 11. However, since 11 is smaller than 101, I want "Route11" to be ahead of "Route101".

I know in iPhone, it has something like, which is basically natural sorting: 

NSSortDescriptor *cityCodeDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name"
ascending:YES selector:@selector(localizedStandardCompare:)];

Is there something like this in Android, or Java.

Thanks.
