title: Java: Switch statements with methods involving arrays
body: <p>Hi guys I'm currently creating a program that allows the user to create an array, search an array and delete an element from an array. Looking at the <code>LibraryMenu</code> method, the first case where you create an array in the switch statement works fine, however the other ones create a "cannot find symbol error" when I try to compile. </p>
  
  <p>My question is I want the search and delete functions to refer to the first switch case - the create Library array. Any help is appreciated, even if its likely from a simple mistake.</p>
