, I know the data type of the result of an arithmetic calculation depends on the data types of the numbers involved in the calculation. For example,
int + int = int
a. But I can't find any references which can give me all these rules. Could someone help me?
b. How to avoid over flow in arithmetic calculation? For example, the results of 2 long may not fit into a long anymore...
Thanks a lot.

Java itself does not check integer arithmetic overflows, but I've found this
interesting tool which does so
