How to Write a Helper Method in Java

A helper method is a special type of method that only other methods of a class can call. It is usually assigned a private access specifier which means that only other methods can call it. Helper methods are like rational numbers, and they are always lower than the highest term. For example, if the maximum number of terms in a number is 40, the smallest fraction is 4. Thus, the fraction 1/4 is lower than 40.

Helper methods are a great way of simplifying code and avoiding complicated calls. Any type of method can be refactored into helpers, including arrays. In addition to avoiding ambiguous or complex calls, helper methods can make code shorter and easier to understand. Here are some helper methods:
