Both. In some rows, t2.number is number and in others t3.number is number. The result of the union all in a single result set. The result set doesn’t know the origin of the values in any particular column (although you could include another column with this information). 3 solved Selecting the right column
The best way I would see to do this would be to use Vectors. This is not like arrays where you need a defined size in order to proceed. Vectors can grow and shrink. See [http://docs.oracle.com/javase/7/docs/api/java/util/Vector.html] for more details. Basing this off the code you have already given I would recommend the following: import java.util.*; … Read more
This can be solved with a breadth first search (BFS) in the graph. This algorithm gives you back a tree whose root is the city you start with and the unique path from there to any other node/city is the one with the fewest possible hops. If you need this information for all your cities/nodes … Read more
The part you’re missing is the return type of the function, and then to actually return that value from the function. At the moment you have void compute_sum(int limit) // compute_sum function { int sum_to_limit; sum_to_limit = limit * (limit + 1) / 2; } A function prototype in C looks pretty much like this … Read more

The only way the problem can exist given the posted code, if the reported exception/line is correct, is when “Somerecords” is not really creating a List<Object[]> object – but a List containing non-Object[] elements. One reason could be the method in question is typed to return a non-generic List, filled with double values. Java will … Read more
