Code
editMay be wildcardReference should be better initialized?
If not, javac can complain with an error:
- "variable wildcardReference might not have been initialized"
I would code it this way:
Generic<?> wildcardReference=new Generic(); // new Generic<>() prohibited as explained in section 'Object Creation with Wildcard'
Bounded Wildcards
editI am a newbie in Java programming, not yet enough comfortable to edit section Wildcard (Java)#Bounded Wildcards. However, I have some ideas that may improve these explanations :
- Add sub-sections
- Upper boun
- Lower bound
- Both bounds
- Give examples as done for Generics in Java#Type wildcards
- Reduce Generics in Java#Type wildcards explanations (once, all the good stuff from Generics in Java#Type wildcards is moved to Wildcard (Java)#Bounded Wildcards)
Article Assumptions
editArticle reads at very high level, presumes knowledge only a very tiny miority of intrtereaders can be assumed to possess while at the same time covering a topic of practical interest to millions of Java programmers. The least Wikipedia can offer is a comprehensible definition subject. This article fails that criteria. — Preceding unsigned comment added by 67.184.124.99 (talk) 16:58, 20 February 2014 (UTC)
