You can expose a field in a class and later wrap it in a getter and setter without having to touch any code that uses that field. Although this works for certain situations, the biggest challenge with the single global variable pattern is ensuring that no one else has used the same global variable name as we have in the page. Moreover, the class field can be initialized right away at declaration. It returns the constructor itself, which can be used for chained calls. Error in the documentation? JSON forms and extensions.

The actual parameters in the constructor, if any, are evaluated, and the values are assigned to the formal parameters of the constructor. This is the new constructor for the class. String is not inserted either before the first String or after the last String. The following code demonstrates how that works. With an array object, you defined the number of values you want to store, and retrieve these values based on their associated index. It prevents the developer from reassigning a new value to the variable, ensuring that the value and data type stay the same and can be reliable to be the same. The first element of the array is removed from the array and returned. Then, all you need to do is call that function from each page in your web application.
