TreeSet類的iterator()方法 (TreeSet Class iterator() method)

• iterator() method is available in java.util package.

  iterator()方法在java.util包中可用。

• iterator() method is used to iterate the elements of this TreeSet is ascending or increasing order.

  iterator()方法用于迭代此TreeSet的元素是升序還是升序。

• iterator() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  iterator()方法是一個(gè)非靜態(tài)方法，只能通過(guò)類對(duì)象訪問(wèn)，如果嘗試使用類名稱訪問(wèn)該方法，則會(huì)收到錯(cuò)誤消息。

• iterator() method does not throw an exception at the time of iterating elements by using iterator().

  通過(guò)使用iterator()迭代元素時(shí)， iterator()方法不會(huì)引發(fā)異常。

Syntax:

句法：

public Iterator iterator();

Parameter(s):

參數(shù)：

• It does not accept any parameter.

  它不接受任何參數(shù)。

Return value:

返回值：

The return type of the method is Iterator, it returns TreeSet element in ascending order.

該方法的返回類型為Iterator ，它以升序返回TreeSet元素。

Example:

例：

// Java program to demonstrate the example // of Iterator iterator() method of TreeSet import java.util.*;public class IteratorOfTreeSet {public static void main(String[] args) {// Instantiates a TreeSet objectTreeSet < String > tree_set = new TreeSet < String > ();// By using add() method is to add// the given object of this TreeSet tree_set.add("C");tree_set.add("C++");tree_set.add("JAVA");tree_set.add("PHP");tree_set.add("SFDC");// Display TreeSetSystem.out.println("TreeSet: " + tree_set);// By using iterator() method is to// iterate the TreeSet elements in an// increasing orderSystem.out.println("tree_set.iterator(): ");for (Iterator itr = tree_set.iterator(); itr.hasNext();)System.out.println(itr.next());} }

Output

輸出量

TreeSet: [C, C++, JAVA, PHP, SFDC] tree_set.iterator(): C C++ JAVA PHP SFDC
