Java ArrayList Tutorial: Adding, Iterating, Sorting, and Removing Elements

public class ArrayListTest { public ArrayListTest() { ArrayList list = new ArrayList<>(); list.add('James'); list.add('Tom'); list.add('Steven'); list.add('Alice'); list.add('Bob'); list.add('Eve'); list.add('Mary'); list.add('Jerry');

    // output all names using index-based loop
    for (int count = 0; count < list.size(); count++) {
        System.out.print(list.get(count) + ' ');
    }
    System.out.println();
    
    // output all names using iterator and remove Tom
    Iterator<String> iter = list.iterator();
    while (iter.hasNext()) {
        String name = iter.next();
        System.out.print(name + ' ');
        if (name.equals('Tom')) {
            iter.remove();
        }
    }
    System.out.println();
    
    // sort the names in ascending order
    Collections.sort(list);
    
    // output all names using for-each loop
    for (String name : list) {
        System.out.print(name + ' ');
    }
    System.out.println();
}

public static void main(String[] args) {
    ArrayListTest test = new ArrayListTest();
