Primitive wrapper class

Imagine you have a toy box that contains some of your favorite toys. Some of these toys can be played with right away because they are already in their original form, but some of them need to be wrapped first before they can be played with.

The same thing happens with certain types of information in computer programming, known as data types. Some data types are easy to use and work with directly, while others need to be "wrapped" in a special kind of package before they can be used.

These packages are called "primitive wrapper classes". They "wrap" or surround primitive data types (like integers or booleans) with a set of methods and properties that make them easier to work with.

For example, imagine you have an integer (a whole number) that you want to work with in your code. You could use it as is, but you might run into issues with things like formatting or comparisons. Instead, you can wrap the integer in an Integer class, which provides tons of helpful methods for manipulating integers.

Overall, a primitive wrapper class makes it easier to work with certain kinds of data in programming by providing extra methods and properties. Just like wrapping up a toy can make it easier to play with, wrapping up certain types of data can make them easier to use in your code!
