java - Raw stack vs. generic Stack<Character> -


it's not error, don't having warnings show in eclipse.

stack raw type. references generic type stack<e> should parameterized

i know can fix providing class character e, since i'll using .charat, rather use <char> because that's type charat returns. there way me use char parameter, , if not, run casting problems using <character>?

the reason have use character , not char generic type parameters in java cannot primitive types. there no way around that. if want use standard java collection framework, have put this.

as far warnings concerned:

  • they warnings, , can suppressed. can in source code (by using @suppresswarning annotations), or changing eclipse java compiler preferences.

  • it possible write genericised equivalent usage of raw types.
