Question

Stack:push() method in Java is used to retrieve or fetch the first element of the Stack or the element present at the top of the StackTrue False

Answer 1

False
The push() method in Java is used to push/add an element onto the top of the stack. It is used to insert an element into the stack, not to retrieve or fetch the first element of the stack. To retrieve the top element of the stack, you would use the peek() method in Java.
