The `static` **`compare()`** method is from class Boolean. We use this method to compare two boolean values and check their equality.

> Class Boolean is imported from the `java.lang.Boolean` package, which impletmets the `Serializable` and `Comparable<Boolean>` interfaces.
# 
## Syntax

---
```java
int compare(boolean x, boolean y)
```
---

## Parameters
1. boolean `x`: First argument value of primitive boolean type.
2. boolean `y`: Second argument value of primitive boolean type.

## Return value
The `compare()` method returns an integer value:

* Equal to 0: `compare()` returns `0` when both `x` and `y` are `true`.
* Less than 0: `compare()` returns a negative number when `x` is `false` and `y` is `true`.
* Greater than 0: `compare()` returns a positive number when `x` is `true` and `y` is `false`.

## Code
Below are some examples to illustrate the usage of the `compare()` method in Java.
* Case #1: As highlighted, `Boolean.compare(x, y)` returns `0` because `x` and `y` are both `true`.
* Case #2: `compare()` returns `-1` because `x` is `false` and `y` is `true`.
* Case #3: `compare()` returns `1` because `x` is `true` and `y` is `false`.

What is the Boolean compare() method in Java?

The Boolean compare() method compares two boolean values, returning 0 if equal, negative if x is false, and positive if x is true.
