The header for the "Firecracker" class, which is a child of "Firework" and comparable, should utilize the "Comparable" interface in its parameterized form. This ensures that only firecrackers can be compared with one another. The header should be defined as follows:
```java
public class Firecracker extends Firework implements Comparable {
// class implementation goes here
}
```
In this header, we declare that the "Firecracker" class extends the "Firework" class using the keyword "extends". This establishes the parent-child relationship between the two classes.
Additionally, we include the "Comparable" interface in the header, specifying the type parameter as "Firecracker". This allows us to compare objects of the "Firecracker" class with each other. The implementation of the "Comparable" interface requires defining the "compareTo" method within the "Firecracker" class, which will provide the logic for comparing two firecracker objects.
By using the "Comparable" interface, we can compare firecrackers based on specific criteria, such as size, color, or any other relevant attribute. This allows for sorting or ordering of firecracker objects in various scenarios.
In summary, the main answer is that the header for the "Firecracker" class should be defined as shown above, incorporating the parent-child relationship with the "Firework" class and utilizing the "Comparable" interface with the type parameter of "Firecracker". This ensures that only firecrackers can be compared with one another.
The "Comparable" interface in Java is used to define a natural ordering of objects. By implementing this interface and providing the "compareTo" method, we can compare objects of the same class based on a specified criteria. In this case, we want to compare firecrackers with each other, so the type parameter of the "Comparable" interface is set to "Firecracker".
By extending the "Firework" class, the "Firecracker" class inherits all the fields and methods of the "Firework" class, establishing a parent-child relationship. This allows the "Firecracker" class to access and utilize the features provided by the "Firework" class.
By including the "Comparable" interface in the header of the "Firecracker" class, we ensure that only firecrackers can be compared with one another. This is because the "compareTo" method will be specific to the "Firecracker" class and will define the comparison logic for firecrackers. Other objects, such as different types of fireworks, will not have this method and therefore cannot be compared with firecrackers.
Overall, this header ensures that the "Firecracker" class has the necessary inheritance from the "Firework" class and the ability to be compared with other firecrackers using the "Comparable" interface.

What+energies+will+be+accepted+by+a+15%+window+placed+around+a+centerline+of+159+kev?
A 15% window placed around a centerline of 159 keV will accept energies within a certain range. In this case, the centerline energy is 159 keV, and the window is 15% of this energy. To calculate the range, we can use the following formula:
Window Range = Centerline Energy * Window Percentage
Plugging in the values, we have:
Window Range = 159 keV * 0.15
Window Range = 23.85 keV
Therefore, the energies that will be accepted by the 15% window placed around the centerline of 159 keV are within a range of 23.85 keV. This means that any energy value within this range, both above and below the centerline energy, will be accepted.

To compute the average of an array of integers called `iArray`, you can use a for loop. Here's an example of how you can do it:
```java
int iSum = 0;
int iAverage;
int arrayLength = iArray.length;
for (int i = 0; i < arrayLength; i++) {
iSum += iArray[i];

given a correctly declared array named stuff, how many elements will be filled with the following loop?
To determine the number of elements that will be filled with a loop in a correctly declared array named "stuff," we need to know the length or size of the array. Without this information, we cannot determine the exact number of elements that will be filled.
However, if we assume that the array "stuff" has a length of "n," and the loop iterates "k" times, then the number of elements filled would be the minimum of "n" and "k." This is because if "k" is larger than the length of the array, the loop will only fill up to the length of the array.
