Question
Can someone please help me to correctly write the following program using Java eclipse.
Part 3) Some basic stats - The final part of the lab is concerned with the collection of a few basic stats, using counters. (a) Modify the program to keep track of all objects input into the system into a counter (an int variable). Increment the counter by one each time an object's name and mass is input. (b) Modify the program to display the 'Total Input Count' at the end, after the user inputs -5 and before ending the program (c) Modify the program again to have another counter, countValid (or something similar), which is only incremented when the object's weight is accepted (between 1000 and 10). Display this counter at the end as well (d) Finally, modify the program to keep a running total of the weight in Newtons of all valid objects. Objects that are too heavy or too light should not be included in this count. (e) At the end, display the total valid weight as well as the average valid weight (total/countValid). See Code Listing 4-13 for calculating the average after the while loop. Sample Output at the end: Enter the object's name>Honda Accord Enter Honda Accord's mass>240 Honda Accord is too heavy. Enter the object's name>Feather Enter Feather's mass>0.001 Feather is too light. Enter the object's name>Running Shoes Enter Running Shoes's mass>2.5 Running Shoes weight is 24.5 Newtons Enter the object's name>Kiwi Enter Kiwi's mass>5.5 Kiwi weight is 53.9 Newtons Enter the object's name>Panda Enter Panda's mass>-5 Total input count: 4 Total valid count: 2 Total valid weight input: 78.4 Average valid weight: 39.2

Exercises Part 1) Simple Input - Mass and Weight. Scientists measure an object's mass in kilograms and its weight in Newtons. Weight = Mass * 9.8 You should write code that does the following (a) Create a scanner object for keyboard input and get an object's name from the user. (b) Get the object's mass from the user. Display the object's name when asking for the mass (See Part 2 for sample output). Note: Directly after calling nextDouble(), also call nextLine(). Java console input can sometimes leave residual newlines, which mess with future inputs. Please refer Code Listing 2-30 and 2-31 on pp 89-91. (c) Calculate the weight with weight = mass * 9.8 (d) Write an if statement that checks the weight. If weight > 1000 Newtons, display "objectName is too heavy!" (Where object name is the name input at step a). If the object weighs less than 10, display "objectName is too light!" Otherwise, display "objectName weighs X", where X is the weight from part c. Use String.format in Section 3.10 to have it display only one decimal point. (e) As always, output can be slightly different so long as the weight and objectName are displayed. (f) Verify that your code works for all three cases before moving on Part 2) Basic Loop - This part extends the code from Part 1 into a loop. (a) Take the code from part 1 and put it into a while loop. The while loop should run until the user inputs a -5, at which point the while loop should end. In this case, the input is a 'sentinel value'. Note: you will have to get the first name and first mass outside of the loop for things to work how I intend it to. See Code Listing 4-11. (b) The input that ends the loop should be the object's mass, not the object's name, to prevent the need to convert data types Sample Output after Part 2: Enter the object's name> Honda Accord Enter Honda Accord's mass> 240 Honda Accord is too heavy. Enter the object's name> Feather Enter Feather's mass> 0.001 Feather is too light. Enter the object's name> Running Shoes Enter Running Shoes's mass> 2.5 Running Shoes's weight is 24.5 Newtons. Enter the object's name> Panda Enter Panda's mass>-5
