The Java.util.Stack.hashCode() method in Java is used to get the hashcode value of this Stack.
Syntax:
Stack.hashCode()
Parameters: The method does not take any parameter.
Return Value: The method returns hash code value of this Stack which is of Integer type.
Below programs illustrate the Java.util.Stack.hashCode() method:
Program 1: Stack with string elements.
// Java code to illustrate hashCode() import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<String> stack = new Stack<String>();
// Use add() method to add elements into the Stack
stack.add( "Welcome" );
stack.add( "To" );
stack.add( "Geeks" );
stack.add( "4" );
stack.add( "Geeks" );
// Displaying the Stack
System.out.println( "Stack: " + stack);
// Displaying the hashCode value of Stack
System.out.println( "The hashCode value is: "
+ stack.hashCode());
}
} |
Output:
Stack: [Welcome, To, Geeks, 4, Geeks] The hashCode value is: -878886256
Program 2: Stack with integer elements.
// Java code to illustrate hashCode() import java.util.*;
public class StackDemo {
public static void main(String args[])
{
// Creating an empty Stack
Stack<Integer> stack = new Stack<Integer>();
// Use add() method to add elements into the Stack
stack.add( 10 );
stack.add( 20 );
stack.add( 30 );
stack.add( 40 );
stack.add( 50 );
// Displaying the Stack
System.out.println( "Stack: " + stack);
// Displaying the hashCode value of Stack
System.out.println( "The hashCode value is: "
+ stack.hashCode());
}
} |
Output:
Stack: [10, 20, 30, 40, 50] The hashCode value is: 38490301
