They are basically the same:

Ineger.valueOf(s)

is the same as calling:

new Integer(Integer.parseInt(s))

I am not entirely sure why both of these exists.

I always use parseInt (because it has a shorter syntax), if in doubt check the API (J2SE API) or J2SE spec

parseInt() returns primitive integet type (int), whereby valueOf returns java.lang.Integer, which is the object representative of the integer. There are cirsumstances where you might want an Integer object, instead of primitive type.

Of course, another obvious difference is that intValue is an instance method whereby parseInt is a static method.

If you don't need the java.lang.Integer object, you should prefer the static method parseInt(), because it doesn't create the unnecessary Integer object.
