/WRITE AN APPLICATION CLASS HIGHARRAYAPP.JAVA TO TEST ALL METHODS DEFINED IN HIGHARRAY.JAVA CLASS. THE APPLICATION SHOULD ALLOW THE USER TO DECIDE THE LENGTH OF THE ARRAY ( ASK FOR USER INPUT AND USE THAT VALUE WHILE INSTANTIATE THE OBJECT OF HIGHARRAY). YOUR PROGRAM SHOULD PROVIDE A MENU OF OPERATIONS. USE JAVA "SWITCH" STATEMENT TO BRANCH TO THE DIFFERENT OPERATIONS.

I'M HAVING A HARD TIME TO LET THE USER INPUT THE ARRAY. COULD YOU PLEASE HELP ME OUT ( I ONLY TRIED FOR CASE 1). THANK YOU
