Question
How can the TextMenu class be designed to accept and display an array of menu items, provide a method to display the menu with numbered choices, and validate and return the users choice as an integer using try/catch in Java?

aircraft in the array will be moved up a position to fill in the gap in the array.
Instance Variables:
O An array that stores all of the menu item options
Methods:
O
O Constructor- This accepts an array of menu items- Be sure to create a new array and
copy the contents from that array into the text menu array. The array should only
display the text options, not the number of the option.
displayMenu()- This method prints the contents of the text menu array. The output
should include the number choices for each item.
O

getChoice()- This method will call the displayMenu and then allow the user to input
their response. The response will be sent to the validateChoice() method and then if
the choice is valid (not -1), then It will return the integer value of the user's choice.
It must re-ask for input if the choice was not valid.
Driver classi
validateChoice()- This method accepts a string that represents the users choice. This
method must use try/catch to convert the string choice to an integer and return -1 if
the user does not enter a number or if choice is outside the acceptable range.
Otherwise, it should return the choice.
