The Java.util.Stack.elements() method of Stack class in Java is used to get the enumeration of the values present in the Stack.
Syntax:
Enumeration enu = Stack.elements()
Parameters: The method does not take any parameters.
Return value: The method returns an enumeration of the values of the Stack.
Below programs are used to illustrate the working of the java.util.Stack.elements() method:
Program 1:
// Java code to illustrate the elements() method import java.util.*;
public class Stack_Demo {
public static void main(String[] args)
{
// Creating an empty Stack
Stack<String> stack = new Stack<String>();
// Inserting elements into the table
stack.add( "Geeks" );
stack.add( "4" );
stack.add( "Geeks" );
stack.add( "Welcomes" );
stack.add( "You" );
// Displaying the Stack
System.out.println( "The Stack is: " + stack);
// Creating an empty enumeration to store
Enumeration enu = stack.elements();
System.out.println( "The enumeration of values are:" );
// Displaying the Enumeration
while (enu.hasMoreElements()) {
System.out.println(enu.nextElement());
}
}
} |
Output:
The Stack is: [Geeks, 4, Geeks, Welcomes, You] The enumeration of values are: Geeks 4 Geeks Welcomes You
Program 2 :
import java.util.*;
public class Stack_Demo {
public static void main(String[] args)
{
// Creating an empty Stack
Stack<Integer> stack = new Stack<Integer>();
// Inserting elements into the table
stack.add( 10 );
stack.add( 15 );
stack.add( 20 );
stack.add( 25 );
stack.add( 30 );
// Displaying the Stack
System.out.println( "The Stack is: " + stack);
// Creating an empty enumeration to store
Enumeration enu = stack.elements();
System.out.println( "The enumeration of values are:" );
// Displaying the Enumeration
while (enu.hasMoreElements()) {
System.out.println(enu.nextElement());
}
}
} |
Output:
The Stack is: [10, 15, 20, 25, 30] The enumeration of values are: 10 15 20 25 30
