How do I randomly select a string from an array in swift?

How do you search for a word in a String array in Java?(10 point Question for any Java wiz)?

• Is my sequentialSearch method set up correctly? I'm having trouble figuring out how to search for a String, compare the String in the method etc. But I think the problem might be in the main. p.s I would also like the program to find the index of the string array when phrase found. it seems like n is returning nothing in main. right now it has a runtime error. Here is my code.... import java.util.Scanner; public class Internet { public static void main(String[] args) { String[] names = new String [4]; names[1] = "kook"; names[2] = "cook"; names[3] = "goop"; names[3] = "soup"; Scanner keyboard = new Scanner(System.in); String newName; int results; System.out.print("\nPlease enter in a name: "); newName = keyboard.nextLine(); results = sequentialSearch(names, newName); if (results != -1) { System.out.print("\nFound the name " + newName ); } else { System.out.print("\nCannot find name " + newName); } } public static int sequentialSearch(String[] names, String name) { for (int n = 0; n < names.length; n++) { if (names[n].equals(name)) return n; } return -1; } }

• Answer:

  names[3] = "goop"; names[3] = "soup"; That can't be good. Array's are zero indexed. names[0] = ""; . . names[3] = "";
