The `empty` method of the `Stack` class checks if the `stack` object contains an element. 

> The `Stack` class is a #key# Last-In-First-Out (LIFO): The element inserted first is processed last and the element inserted last is processed first. #key# stack of objects.

#    
## Syntax 

```
public boolean empty();
```

## Return Value
 If the `stack` object is empty, the method returns `true`. Otherwise, it returns `false`.


## Code 

import java.util.Stack;
class StackIsEmptyExample  {
    public static void main( String args[] ) {
        // Creating Stack
        Stack<Integer> stack = new Stack<>();

        // Print Stack
        System.out.println("The Stack is: " + stack);
        System.out.println("Is Stack Empty: " + stack.isEmpty());

        // add elememts 
        stack.push(1);

        // Print Stack
        System.out.println("The Stack is: " + stack);
        System.out.println("Is Stack Empty: " + stack.isEmpty());
    }
}

## Explanation

In this example, we create a `stack` object. Initially, the `stack` object doesn't contain any elements, so the `empty` method will return `true` when we call `stack.empty()`. 

We then added one element to the `stack` object using the `push` method. Now when we call the `empty` method, `false` is returned because the `stack` object is not empty.  

What is the Stack.empty method in Java?

The `empty` method in Java's Stack class checks if the stack is empty, returning `true` if it is, `false` otherwise.
