Create, using NetBeans, a complete Java program called -- ( CalcWeightedAvg ) according to the
following guidelines.
The program should use methods to carry out all computations.
The method
readIntValues
should take no arguments, prompt the user to enter one line of
between 5
and 10
space-separated integers with values between 0 and 100 (inclusive) and
return an array list
of
these integers.
The method
getWeight
should take no arguments, and it should prompt the user for a double with
value greater than 0.0 but less than or equal to 1.0, and return as a double the value the user entered.
The method
calcWeightedAvg
should return a double and take two parameters:
an array list of
integers
and a double called weight (with values greater than 0.0 but less than or equal to 1.0). It
should
calculate the average of the values in the integer array by
removing the lowest value from
consideration and calculating the average of the other value
s
, and then multiply that average by the
weight, and return the result.
Note: If there are several “lowest” values, remove only one of them.
For example, if calcWeightedAvg is invoked as calcWeightedAvg(intArrayList, weight) (with weight =
0.50) then it should calculate the average of all values but the lowest value in intArray, multiply that
average by 0.50 and return the result to the main method, which will then display that value to the
user.
Example:
integer input: 20 20 40 60 80 100
weight input: 0.50
calcWeightedAvg invoked as calcWeightedAvg(intArrayList, weight) returns 30.0, because one of the
“20” values is dropped from consideration when calculating the average.
Your output should be something like this: “With input values 20 20 40 60 80 100 and with a weight
of 0.50, when dropping the lowest value, the weighted average of the remaining values is 30.0.”
2. Export your project from NetBeans as a zip file (File → Export Project → To ZIP)
