Usage

From source file:MainClass.java

public static void main(String args[]) throws Exception {

    String elements[] = { "A", "C", "D", "G", "F" };
    Set set = new TreeSet(Arrays.asList(elements));
    Iterator iter = set.iterator();
    while (iter.hasNext()) {
        System.out.println(iter.next());
    }/*  w ww. jav  a2  s.com*/
}

From source file:SearchTest.java

public static void main(String args[]) {
    String simpsons[] = { "Bart", "Hugo", "Lisa", "Marge", "Homer", "Maggie", "Roy" };

    // Convert to list
    ArrayList list = new ArrayList(Arrays.asList(simpsons));

    // Ensure list sorted
    Collections.sort(list);//from  w  w w. ja va 2s.c  o  m
    System.out.println("Sorted list: [length: " + list.size() + "]");
    System.out.println(list);

    // Search for element in list
    int index = Collections.binarySearch(list, "Maggie");
    System.out.println("Found Maggie @ " + index);

    // Search for element not in list
    index = Collections.binarySearch(list, "Jimbo Jones");
    System.out.println("Didn't find Jimbo Jones @ " + index);

    // Insert
    int newIndex = -index - 1;
    list.add(newIndex, "Jimbo Jones");
    System.out.println("With Jimbo Jones added: [length: " + list.size() + "]");
    System.out.println(list);
}
