title: Converting a Object[] array to an int [] array in java?
body: <p>It appears there is no easy way of doing this, but this is what i've done so far and if someone could correct it to make it work that would be great. At "newarray [e] = array [i].intValue ();" i get an error "No method named "intValue" was found in type "java.lang.Object"."
  Help!</p>
