Answer:

throw and throws represent different constructs in Java programming language.

Explanation:

throw is used to explicitly throw an Exception from within a code segment.

For example:

public void throw_test(String str){

if(str==null) throw new NullPointerException();

}

throws is used to specify an exception list which may be thrown by a method:

For example:

public String readFromFile(File f) throws IOException {

.....

// Some code fragment which could throw a IOException

}

valentina_108 [34]

Answer:

policy_num = int(input("Enter policy number: "))
lastName = input("Enter last name: ")
firstName = input("Enter first name: ")
premiumDate = input("Enter premius due date (mm/dd/yyyy): ")
numAcc = int(input("Enter number of driver accident in the past three years: "))
if(policy_num <1000 or policy_num > 9999):
policy_num = 0
dateComp = premiumDate.split("/")
month = int(dateComp[0])
day = int(dateComp[1])
year = int(dateComp[2])
if(month < 1 or month > 12):
month = 0
day = 0
year = 0
else:
if(month == 1 or month == 3 or month == 5 or month == 7 or month == 8 or month == 10 or month == 12):
if(day < 1 or day > 31):
month = 0
day = 0
year = 0
elif(month == 4 or month == 6 or month == 9 or month == 11):
if(day <1 or day > 30):
month = 0
day = 0
year = 0
elif(month == 2):
if(day < 1 or day > 29):
month = 0
day = 0
year = 0
print("Policy number: " + str(policy_num))
print("Last name: " + lastName)
print("First name: " + firstName)
print("Premium Date: " + str(month) + "/" + str(day) + "/" + str(year))
print("Number of driver accidentin the last three years: " + str(numAcc))

Explanation:

The solution code is written in Python 3.

Firstly use input function to prompt user to enter all the necessary insurance policy data (Line 1 - 5).

Next create an if statement to validate the input policy number. If the policy number is not within the range of 1000 - 9999, set the policy number to zero (Line 7 -8).

Next, split the input premium date into month, day and year (Line 10 -13). It is followed by checking the month if it is between 1 - 12. If not, set the month, day and year to zero (Line 15 - 18). Otherwise the program will proceed to validate the month based on the maximum and minimum number of days for a particular month (Line 20 - 34). If the day is out of range, set month, day and year to zero.

Lastly, use print function to display the policy data (Line 36 - 40).

What is required to display content on transparencies?

VladimirAG [237]

An overhead projector is required to display content on transparencies. A transparency is a thin sheet of plastic in which light is reflected upon to display content.The light source emits light towards the transparency and then the image is displayed on the wall. Usually, this light source comes from below and lights upward and so the content is depicted above or overhead.

german

Answer:

visual encoding

Explanation:

According to my research on the three types of encoding methods, I can say that based on the information provided within the question Kaydence is best described as capitalizing on visual encoding. Which is the act of associating a certain something with a picture in order to store it into memory, as opposed of associating it with sound or words. In this situation Kaydence is associating it with a networking diagram she drew.

State 3 file formats explain them in an understanding manner apart from Microsoft word and PDF

natita [175]

Answer:

Hope below explanations are enough.

Explanation:

1. JPEG (or JPG) - Joint Photographic Experts Group

JPEGs might be the most common file type you run across on the web, and more than likely the kind of image that is in your company's MS Word version of its letterhead. JPEGs are known for their "lossy" compression, meaning that the quality of the image decreases as the file size decreases.

You can use JPEGs for projects on the web, in Microsoft Office documents, or for projects that require printing at a high resolution. Paying attention to the resolution and file size with JPEGs is essential in order to produce a nice looking project.

2. PNG - Portable Network Graphics

PNGs are amazing for interactive documents such as web pages, but are not suitable for print. While PNGs are "lossless," meaning you can edit them and not lose quality, they are still low resolution.

The reason PNGs are used in most web projects is that you can save your image with more colors on a transparent background. This makes for a much sharper, web-quality image.

3. GIF - Graphics Interchange Format

GIFs are most common in their animated form, which are all the rage on Tumblr pages and in banner ads. It seems like every other day we have a new Grumpy Cat or Honey Boo Boo animated GIF. In their more basic form, GIFs are formed from up to 256 colors in the RGB colorspace. Due to the limited number of colors, the file size is drastically reduced.

This is a common file type for web projects where an image needs to load very quickly, as opposed to one that needs to retain a higher level of quality.

4. TIFF - Tagged Image File

A TIF is a large raster file that doesn't lose quality. This file type is known for using "lossless compression," meaning the original image data is maintained regardless of how often you might copy, re-save, or compress the original file.

Despite TIFF images' ability to recover their quality after manipulation, you should avoid using this file type on the web -- it can take forever to load. TIFF files are also commonly used when saving photographs for print.

5. PSD - Photoshop Document

PSDs are files that are created and saved in Adobe Photoshop, the most popular graphics editing software ever. This type of file contains "layers" that make modifying the image much easier to handle. This is also the program that generates the raster file types mentioned above.

The largest disadvantage to PSDs is that Photoshop works with raster images as opposed to vector images.
