As my AP Computer Science teacher eloquently said:
"You can't let strangers touch your private parts"
Therefore, if data was not hidden, a client class can modify all the variables(given that it is not a final constant) by simply calling:
className.variableName = newWrongData;
By using special methods to access the variables, the class can change its internal implementation, without breaking compatibility with other classes that are already using it.
Encapsulation also implements data hiding in an object oriented programming design. By encapsulating various methods & data objects into a single class they can also be hidden from all the other classes. You can declare the variables and methods as private and that way you can hide the data from the other classes in the application.

No. Logic should never go in a constructor; constructors should only be used to instantiate and initialize object data.
Data hiding is used method used in Object-Oriented programing to hide information within computer code
you should go in your basement and hide under a heavy object.

Acitex data object database
You can hide a column or row, so they do not appear or you can format the cell contents to be white instead of black (format cell contents to the same color as the cell background).
