Primitive data types in Java are fundamental building blocks that efficiently store different kinds of simple data, such as numbers, decimals, characters, and boolean values, much like specialized containers in a kitchen.

Welcome back to CodeChef. Imagine
telling your computer about your age, a
price, a grade, or whether something is
true or false. How does Java store all
these different kinds of information?
That's where primitive data types come
in. Think of primitive data types like
containers in a kitchen, a small jar for
sugar cubes, a bigger jar for rice, one
container for a single fruit, and even a
box labeled yes or no. Each container
can hold only one type of thing, keeping
everything organized. In Java, primitive
types are the simplest way of storing
data. There are eight of them. bite,
short, int, long, float, double, char,
and boolean. They allow Java to
efficiently store numbers, decimals,
single characters, and true or false
values. Here's a simple example using
only what we've learned. nth age equals
21. Double price equals 99.99.
Charrade equals a boolean is Java fun
equals true. The first line stores 21 as
a number. The second stores 99.99 as a
decimal. The third keeps the character
a. And the fourth stores the value true.
When we print them, the output is 21 99.99
99.99
a true. A few quick tips. Use int for
most whole numbers. Use double for
decimals. Remember, char uses single
quotes. And boolean is always either
true or false. Now it's your turn. Try
the beginner friendly code chef problem
called print your variables where you
declare variables of different types and
print their values. Today you learned
that primitive data types are Java's
building blocks storing numbers,
decimals, characters, and true or false
values. Code debug repeat build mastery
