Japanese only sex cams - Validating input java

As I said, I am new and have used lots of While Loops to achieve the desired behaviour and this is probably a horribly inefficient way of doing things.Hopefully someone is able to point me in the right direction, Conor My best attempt thus far: This allows the code to run but does not address the invalid input error.expects an integer, next Double expects a double, next Float expects a float and next Line expects a string.

First, we set up a method to test whether or not the accepted input can be converted to a specific type: The loop is called with a string parameter that decides which message the user will see.

This message will repeat itself each time the loop requests for the input.

I'm new to Java (actually only on my third day) but enjoy pushing myself when it comes to learning a new bit of code, I did the same when learning MATLAB as part of my Degree.

In essence I like going one step further than what each particular lesson is trying to teach.

Input validation is performed to ensure only properly formed data is entering the workflow in an information system, preventing malformed data from persisting in the database and triggering malfunction of various downstream components.

Input validation should happen as early as possible in the data flow, preferably as soon as the data is received from the external party.

Whenever a user is asked to provide input, the program should expect errors.

This is true for almost any language and almost any case; you should protect your My SQL code from sql-injections, your php input fields from scripts, your javascript from infinite loops, your java code from non-fitting variable type.

The purpose of this code is to produce a consistent method to validate user input, and not let the program proceed until the user has inputted a correct type.
