A boxed primitive is created from a String, just to extract the unboxed
primitive value.It is more efficient to just call the static parseXXX
method.


Before:
int number = Integer.valueOf("42", 8);
new Double("42.42").doubleValue();

After:

int number = Integer.parseInt("42", 8);
Double.parseDouble("42.42");
