8. new Integer vs Integer.valueOf coderanch.com
hi Matt, try the following code and review the results for different s argument values. you will notice the difference. i am not sure about the reason but this what i observed.

9. parseInt(String) or Integer.valueOf(s).intValue coderanch.com
OK, It's not 10am and I haven't had my first coffee of the morning but...

14. Integer.valueOf( int i ) vs. Integer.valueOf( String s )? forums.oracle.com
an inspection of the implementation ( 1.6.0_04 ) indicates that valueOf( int i ) and valueOf( String s ) differ in an interesting way. the former attempts to return an Integer from the internal cache, while the latter always constructs a new Integer after parsing. naively, one might expect valueOf( String s ) to parse to a primitive, then invoke valueOf( ...
