What is the correct way to declare and instantiate a stack of Strings in Java's Stack class?

A) Stack myStack = new Stack ( );
B) Stack myStack = new Stack( );
C) Stack = new Stack ( );
D) Stack String myStack;

Answer:

The correct way to declare and instantiate a stack of strings in Java's Stack class is 'Stack myStack = new Stack();'.

In Java, to correctly declare and instantiate a stack of Strings using Java's Stack class, you need to follow the syntax 'Stack myStack = new Stack();'.

Now, let's break down the statement:

Stack is the Java class used to create a stack data structure.

is the type parameter specifying that the stack will be holding Strings.

myStack is the variable name for the newly created stack.

new is used to instantiate or create the object.

Stack() is the constructor method for the Stack class, which is called to create a new Stack object.

By following this syntax, you correctly declare and instantiate a stack of Strings using Java's Stack class.
