Transcribed Image Text:1. Use the Active Code window below to create 4 parallel arrays and intialize them using initialization
lists that represent the data below. Remember that the order of these arrays has to match so that you
can use the same index and get corresponding values out.
• Countries: China, Egypt, France, Germany, India, Japan, Kenya, Mexico,
United Kingdom, United States
• Capitals: Beijing, Cairo, Paris, Berlin, New Delhi, Tokyo, Nairobi, Mexico
City, London, Washington D.C.
• Languages: Chinese, Arabic, French, German, Hindi, Japanese, Swahili,
Spanish, English, English
• Filenames for map images: China.jpg, Egypt.jpg, France.jpg,
Germany.jpg, India.jpg, Japan.jpg, Kenya.jpg, Mexico.jpg, UK.jpg, US.jpg
2. Choose a random number using Math.random() and the length of one of the arrays and save it in a
variable called index.
3. Print out the country name, its capital, and its language, and the map image for that country using the
random index to access the corresponding item in each parallel array. For the images, the
printHTMLimage method has been given to get the image URL online and print it out as an HTML
image.

public static void main(String[] args)
