 **`compare`** is a static method of the `Double` class which is used to compare two `double` values. 

# 
## Syntax 

```java
public static int compare(double x, double y);
```

## Parameters

The function takes in two `double` values as a parameter.
## Return value
This method returns:

* `0` if both the values are the same. 
* A value less than zero, if `x` is less than `y`.

* A value greater than zero, if the `x` is greater than `y`.

Double.compare(x,y)

class DoubleCompare {
    public static void main( String args[] ) {
        double ten = 10d;
        double twenty = 20d;
        
        System.out.println("ten, ten : " +  Double.compare(ten, ten));
        System.out.println("twenty, twenty : " +  Double.compare(twenty, twenty));
        System.out.println("ten, twenty : " +  Double.compare(ten, twenty));
        System.out.println("twenty, ten : " +  Double.compare(twenty, ten));
    }
}

## Explanation

In the code above:

* We created two `double` variables: 

```
ten = 10d;
twenty = 20d;
```

* We used the `compare` method of the `Double` class to compare the `double` values. First, we compared the same values: 

```
compare(ten,ten);
compare(twenty, twenty);

``` 
The `compare` method returns `0`, as both the compared values are the same.

* Then, we compared `ten` with `twenty`:

```
compare(ten, twenty);
```
The `compare` method returns a value `< 0`, as the first value is less than the second value.

* Then, we compared `twenty`  with `ten`.

```
compare(twenty, ten);
```
The `compare` method returns a value `> 0`, as the first value is greater than the second value.
