Help with a ramdom word selection

[nomad]

Hello everyone.
I'm trying to write a ramdom word program using a arraylist.

here is the code so far.

 class WordClass1 {// there is another PersonClass1 project. 

 
private String wd_id;
 
private String word_name;
 
 
 
public WordClass1(String id) {
 
wd_id = id;
 
}
 
public WordClass1(String id, String Wd) {
 
this.wd_id = id;
 
this.word_name = Wd;
 
 
 
}
 
 
 
// accessors
 
public String getWd_id() {return wd_id;}
 
 
 
public String getWord() {return word_name;}
 
 
 
 
 
 
 
public String toString() {
 
return "(" + wd_id + word_name + ")";
 
}
 
 
 
}//close class Person class
 
 
 
public class HangmanWords {
 
static ArrayList<WordClass1> arlist;
 
static Scanner kbd;
 
 
 
public static WordClass1 makePerson() {
 
WordClass1 temp = null;
 
 
 
// prompt for data
 
String id;
 
String Wd;
 
 
 
System.out.print("Enter ID Number ==>");
 
id = kbd.next();
 
 
 
System.out.print("Enter Last Name ==>");
 
Wd = kbd.next();
 
 
 
 
 
// make an object
 
temp = new WordClass1(id, Wd);
 
 
 
return temp;
 
}
 
 
 
 
 
public static void main(String[] args) {
 
// make array list object
 
List < WordClass1 > arlist = new ArrayList < WordClass1 > ();
 
arlist.add(new WordClass1("A1", "STRING"));
 
arlist.add(new WordClass1("A2", "PERSON"));
 
arlist.add(new WordClass1("B1", "CLASS"));
 
arlist.add(new WordClass1("B2", "JAVA"));
 
System.out.println(arlist);
 
 
 
 
 
// make a scanner
 
kbd = new Scanner(System.in);
 
 
 
int choice;
 
System.out.println("Make a Section: ");
 
System.out.println("1. Enter W ");
 
System.out.println("2. Get the word ");
 
System.out.println("3. Exit this Program ");
 
System.out.print("\nPlease press Enter afer each response");
 
System.out.println("\nEnter your choose please: ");
 
choice = kbd.nextInt();
 
kbd.nextLine();
 
if (choice == 1) { 
 
 
 
// create words 
 
}
 
if (choice == 2) { // if 2 is select go to find
 
 
 
int randomIndex = ((Iterator<WordClass1>) arlist).next().getWord().length();
 
 
 
if (choice == 3) {
 
System.out.printf("Good bye");
 
}// close the choice == 3
 
 
 
 
 
// print out all elements of array list
 
for (WordClass1 idx : arlist) {
 
System.out.printf("Employee here are the list of all Employees Empoyeed");
 
System.out.printf("Employee Id is %s%n", idx.getWd_id());
 
System.out.printf("Name is %s %s%n", idx.getWord());
 
System.out.printf("Name is %s %s%n", randomIndex);
 
System.out.println("--------------------");
 
}//close for loop
 
}
 
}//close main
 
}//close public class
 
 

my problem lies here in which I'm trying to get the word selected.

int randomIndex = ((Iterator<WordClass1>) arlist).next().getWord().length();

I get this error
Exception in thread "main" java.lang.Class CastException: java.util.Array List at hangman.Hangman Words.main(Hang manWords.java:1 17)

any help would be great.

You are trying to cast an arraylist into an Iterator. That won't work.
To get an Iterator from an arraylist just do
arlist.iterator ();

P.S It's always a good idea to split long statements into shorter onse so you can see easily what's going on.
