JAVA create a new Java class, Bucket. Instances of this class will represent a bucket that can be filled with water. When you create a new Bucket object, that new object will represent a bucket with a particular capacity, capacity and certain contents, contents. The units of measurement are not important to this exercise, but you could imagine that it was litres.

The constructor for a Bucket should take the capacity as an argument. The constructor's signature should thus be Bucket(double capacity).

In your object, both capacity and contents should be stored as doubles. Because capacity and contents are distinct properties of each object (not properties of the class), they need to be declared as instance fields, not class fields. This means you don't use a static qualifier when you declare the field. The capacity field will never change (the capacity of a bucket is something that does not (normally) change), so it can be declared as final. Both fields should be private to the Bucket class.

The Bucket class should have four public instance methods (not static methods).

The first is getCapacity(), which returns a double reflecting the capacity of the bucket. The second is getContents(), which returns a double reflecting the current contents of the bucket. The third is empty(), which will empty the bucket (its contents will then be zero), and will return the contents of the bucket before it was empty (i.e. how much was emptied from the bucket). The fourth is add(double amount), which will add the given amount to the bucket, and increase the contents accordingly, but it will never increase the contents to be more than the capacity (i.e. any extra water will be spilled, so the total contents can never be higher than the capacity). The add method does not return a value, therefore the return type is void.

You should create a main method, and in that method, declare two local variables: big and small, both of type Bucket. Initialize big by instantiating a new bucket with capacity 10.0. Initialize small by instantiating a new bucket with capacity 1.0. Use the add() method to add 20.0 to each bucket then print out the bucket contents using getContents(). You should find that both buckets are full to capacity, but not more. Then use empty() to empty the big bucket and print out the bucket's contents, and ensure that it is in fact empty. Then empty the small bucket into the big bucket. Print out the contents of each of them and ensure that the small bucket is empty and the big bucket has 1.0 in it.
