Program Plan Intro

Program plan:

SumArrayValues.java

• Create a class named “sumArrayValues”.
  • Create a function named “sumWithoutSmallest()” that calculates the sum of an array of values, except for the smallest one in an array.
    • Declare a variable “totalResult” and assign the value “0”.
    • Declare a variable “smallest” and assign the initial array value “val[0]”.
    • Using the “for” loop, compute the total value of an array except the smallest value.
      • The conditional statement “if (val[x] < smallest)” checks whether the number stored in the variable “smallest” is less than or not.
        • If the condition is true, the smaller value will be stored in the variable “smallest” . In case if the condition is false it will go away from the loop and computes “totalResult = totalResult + val[x];”.
        • It returns a value by subtracting “totalResult - smallest;”.
  • Create a main function.
    • Declare and initialize the array “double[] sum = new double[LENGTH];” elements with the size “100”.
    • Assign the current “size” of the array as “0”.
    • Using print statement enter the sum values up to “100”.
    • Using scanner class, create an object “in” for reading the input values of various types “Scanner in = new Scanner(System.in);”.
    • The “while” loop is used to read each input and store it into the array “sum” and it increments the “size” value at each iteration.
    • The conditional statement “if (sum.length == 0)” checks whether length is equal to “0” or not.
    • Call the function “sumWithoutSmallest()” and pass the two arguments  “sum, size” to the function for finding the smallest value and store the sum result into the “total” variable.
    • Print the total sum except the smallest value in the array.
