When I run my program it gives me these exceptions and I don't
know what it means by it :
Exception in thread "main" java.lang.NumberFormatException: For
input string: "Code" Does anyone know what I need to change for
this to work?
Homework Answers
NumberFormatException occurs when you are giving a string input for an integer or a double or float variable
For Example -
int num = Integer.parseInt(scan.nextLine());
will cause an exception if you enter "code" or any other string instead of an integer because it tries to parse it as an integer

My question is ... how you keep entering user until is valid?
When I entered any number that is invalid input, works fine. I keep entering input value. However, when I entered A , it terminates the program. How do I keep entering the user even if the inputs are String?

Exceptions Lab In this lab you will get practice with exceptions by adding them to a class that represents bank accounts. I have provided two files, BankAccount.h and BankAccount.cpp, which have the code for the class itself. Your task is to modify the code to have it throw exceptions under the conditions listed below, then write a main which uses try/catch blocks to display error messages when the...

Google if you don't know what 'env variables' means things like current to, just like command line arguments @ run time. env variables are that the program has access path, name of shell etc,

I am required to use the try - catch block to validate the input as the test data uses a word "Thirty" and not numbers. The program needs to validate that input, throw an exception and then display the error message. If I don't use the try - catch method I end up with program crashing. My issue is that I can't get the try - catch portion to work. Can you please help? I have attached what I have...

I need to creatre a C++ program that can modify the producer and consumer. My main programmig language is C++. Modify "Producer and Consumer Problem" from lecture note so that it can use all buffer space, not "buffersize – 1" as in the lecture note. This program should work as follows: 1. The user will run the program and will enter two numbers on the command line. Those numbers will be used for buffersize and counter limit. 2. The main...
