Question

USING DOUBLE ARRAYS TO STORE TEST SCORES

AND

USING JOPTIONPANE TO ASK FOR SCORES.

The calcAvarage method calculates the average score. This method must accept a double

array as the sole parameter. It loops through the array elements to add up their values. It

then calculates the average and returns it as a double.

? The scores must be formatted as two places following the decimal, using a DecimalFormat

object.

? The display of grade determination and calculation results may be done in a console

IF U KNOW WHA CHU DOING IT SHOULD TAKE LESS THAN 15 MINUTES TO DO IT AND I WILL BE GREATLY APPRECIATIVE  MEOWW

Explanation / Answer

import javax.swing.*;

import java.text.DecimalFormat;

class averageScore

{

static double calcAverage(double value[])

{

int len = value.length;

double sumScore = 0;

for(int i = 0; i < len; i++)

sumScore += value[i];

sumScore = sumScore / len;

return sumScore;

}

public static void main(String args[])

{

String values = JOptionPane.showInputDialog(

null, "Please enter the scores separated by commas: ");

int i,j, sum = 0,k = 0;

for(i=0; i<values.length(); i++)

if(values.charAt(i) == ',')

sum++;

double value[] = new double[sum+1];

values = values + ",";

i=0;

while(i < values.length())

{

if(values.charAt(i) != ',')

{

for(j = i+1; j<values.length(); j++)

{

if(values.charAt(j) == ',')

break;

}

value[k++] = Double.parseDouble(values.substring(i,j));

i = j+1;

}

}

double res = calcAverage(value);

DecimalFormat tmp = new DecimalFormat("0.00");

System.out.println("The average score is "+tmp.format(res));

}

}

Code runs smoothly!
