Hi Wong,
Thanks for identifying the problem.
i have read the rules
2)We can box and widen..//for this can you explain with example.
3)We cannot widen from one wrapper type to another
eg
ublic static void go(Long x) {}
Integer x=5;
go(5);
Above example is what rule 3 says? Please correct if iam wrong!!!
4)We cannot widen and box:
eg
ublic static void go(Long x) {}
int x=5;
go(5);
Regards
Kirba.
