One of the real world problem that can solved using Stack is Checking whether the paranthesis is balanced or not in a Code editor.
For example "{}" this is an example of a balanced paranthesis.Since the stack is last in First out Data structure.This property is used to solve the above problem as in the case of balanced parantheses opening parantheses is followed by its closing counterpart.If that is not the case then the Parantheses is not balanced.
To solve this problem using stack we will insert the opening parantheses into the stack and when the closing parantheses is encountered we will check the top of the stack if that corresponds to the same opening parantheses then we will pop the stack.
else we will return false.
At the end of parsing the document we will see if the stack is empty or not,If it is not empty then that means parantheses is not balanced.
If stack is not used for this problem then this would become tedious as we have to keep track of individual opening parantheses and when ever closing parantheses is encountered then we have to check the previous parantheses.This can be done using arrays also.But the computation would become bit complicated.

Queues and Stacks Purpose: To review queues and stacks in Java, and to use the built-in Stack class and Queue interface. The Stack class is a generic class containing these methods: public void push(E value) - pushes a new value onto the Stack public E pop() - pops the next value off of the stack and returns it; throws EmptyStackExceptionl if stack is empty public E peek() - returns the next value on the Stack but does not pop it...

Create a real world scenario that would involve a vector field and create a problem to be solved involving the vector field and the real world scenario. You must give a formula for the vector field, describe the various variables involved, and explain what the solution to your problem would be finding. Do NOT actually solve the problem you create.
