Java Program: Finding Maximum Value in a Stack

How does the Java program find the maximum value in a stack?

The program creates a stack with 7 elements, prints all elements, and finds the maximum value in the stack. How is this achieved?

Explanation:

In this program, we first create a stack called `stack` using the `Stack` class from the `java.util` package. We specify that we want to create a stack with 7 elements by setting the value of `n` to 7. We then use a for loop to push the numbers 1 to 7 onto the stack.

Finally, we use a separate method called `findMaxValue` to find the maximum value in the stack. We initialize `maxValue` to the smallest possible integer value using `Integer.MIN_VALUE`. We then iterate over the elements in the stack again and compare each element to the current `maxValue`. If an element is greater than `maxValue`, we update `maxValue` to that element. After iterating over all the elements, we return the final `maxValue`.

When we run the program, it will print all the elements in the stack (1 to 7) and then the maximum value in the stack, which in this case is 7.
