i have a code in java that does a binary search on a given array to determine if a user input number exist in the given array. I must reprompt the user if the number is not in the array to enter another number to determine if it is in the array. This is where i have trouble:in the last part of the code I use a while loop to reprompt but when i run the program and test it still loops that the number is not in the array even though it is. how do i solve this with out for loops or another array

.I'm sure its something super simple i just dont get it. this is the last part of my code; the last else statement works, its just reprompt if statementand while above that doesn't. And i have already coded the binary search.
