The [[Java (programming language)|Java programming language]] allows the programmer to encapsulate data. Encapsulation of data is done to protect the data. If you are writing a piece of software with delicate data, such as a length and width of a window, you can prefix a variable declaration with the keyword "private". The piece of data that has been declared private will only be viewable by methods and constructors from within the same class.
