# Java: Constants

Some data, such as mathematical constants, never changes. Take the number π. Approximately it is always equal to `3.14`

and cannot change.

To access such data in Java, it is customary to use constants.

```
final var PI = 3.14;
System.out.print(PI); // 3.14
```

Constants are usually called uppercase letters with `_`

as a separator. A constant, like a variable, can be used in any expression. The only restriction is that the constant cannot be changed, which sounds quite logical.

## Instructions

Create the constant `DRAGONS_BORN_COUNT`

and write the number 3 in it - the number of dragons born to Dayenerys.
