The following example demonstrates how to use the hasMoreElements and nestElement methods of the Enumeration class to traverse and output the contents of the HashTable:
/* author by w3cschool.cc Main.java */ import java.util.Enumeration; import java.util.Hashtable; public class Main { public static void main(String[] args) { Hashtable ht = new Hashtable(); ht.put("1", "One"); ht.put("2", "Two"); ht.put("3", "Three"); Enumeration e = ht.elements(); while(e.hasMoreElements()){ System.out.println(e.nextElement()); } } }
The output result of running the above code is:
Three Two One
The above is the Java example - Use Enumeration to traverse the contents of HashTable. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
