Stack iterator() method in Java with Example
The Java.util.Stack.iterator() method is used to return an iterator of the same elements as that of the Stack. The elements are returned in random order from what was present in the stack.
Syntax:
Iterator iterate_value = Stack.iterator();
Parameters: The function does not take any parameter.
Return Value: The method iterates over the elements of the stack and returns the values(iterators).
Below program illustrates the use of Java.util.Stack.iterator() method:
Example 1:
import java.util.*;
import java.util.Stack;
public class StackDemo {
public static void main(String args[])
{
Stack<String> stack = new Stack<String>();
stack.add( "Welcome" );
stack.add( "To" );
stack.add( "Geeks" );
stack.add( "4" );
stack.add( "Geeks" );
System.out.println( "Stack: " + stack);
Iterator value = stack.iterator();
System.out.println( "The iterator values are: " );
while (value.hasNext()) {
System.out.println(value.next());
}
}
}
|
Output:
Stack: [Welcome, To, Geeks, 4, Geeks]
The iterator values are:
Welcome
To
Geeks
4
Geeks
Example 2:
import java.util.*;
public class StackDemo {
public static void main(String args[])
{
Stack<Integer> stack
= new Stack<Integer>();
stack.add( 10 );
stack.add( 20 );
stack.add( 30 );
stack.add( 40 );
stack.add( 50 );
System.out.println( "Stack: " + stack);
Iterator value = stack.iterator();
System.out.println( "The iterator values are: " );
while (value.hasNext()) {
System.out.println(value.next());
}
}
}
|
Output:
Stack: [10, 20, 30, 40, 50]
The iterator values are:
10
20
30
40
50
