You have been hired by Planet Poachers to write a Java console application that reads, converts,
sorts, and writes planet data. Create text file PlanetDataEnglish.txt, paste the following data into
it, and place the file in your project folder.
PlanetDataEnglish.txt
Planet Escape Velocity (miles/s) Mean Temperature (F) Number of Moons
Mercury 2.7 333 0
Venus 6.4 867 0
Earth 7.0 59 1
Mars 3.1 -85 2
Jupiter 37.0 -166 67
Saturn 22.1 -220 62
Uranus 13.2 -320 27
Neptune 14.6 -330 13
Pluto 0.7 -375 5
Create the following methods:
Column Purpose
readTextFile To read the data from file PlanetDataEnglish.txt into four parallel arrays: planets,
escapes, means, and moons.
printArrays To print the unsorted, converted, and sorted data using the appropriate column
headers.
convertArrays To convert the escape velocities from miles/s to km/s, and to convert the mean
temperatures from Fahrenheit to Celsius.
bubbleSortArray To sort the data by planet name in ascending order. Note that when values are
swapped in one array, the same values must be swapped in the other arrays.
writeTextFile To write the data to file PlanetDataMetric.txt in the same layout as the input file.
Sample Output on .txt file
PlanetDataMetric.txt
Planet Escape Velocity (miles/s) Mean Temperature (F) Number of Moons
Earth 11.3 15 1
Jupiter 59.5 -110 67 …
