Question

PLEASE LET ME KNOW WHERE I AM GOING WRONG IN THIS CODE.

Allow a user to enter any number of double values up to 20. The user should enter 99999 to quit entering numbers.

Display an error message if the user quits without entering any numbers; otherwise, display each entered value and its distance from the average.

My code is below:

import java.util.Scanner;

public class DistanceFromAverage {

public static void main(String[] args) {

// declaration of values as double type

double[] values = new double [20];

int count = 0;

double sum = 0;

double average;

//Declaration of scanner object

Scanner input = new Scanner(System.in);

// Get values from user and iterate the loop up to 20 numbers

for (int i = 0; i < 20; i++) {

//Display statement

System.out.print("Enter the value(99999 to exit):");

double number = input.nextDouble();

// it breaks when values is 99999

if (number == 99999) {

break;

} else {

count++;

values[i] = number;

sum += values[i];

}

}

//checks whether count is zero or not

if (count == 0)

//Display statement for an error message

System.out.printIn("Error! Please enter any values");

else {

//calculation of average

average = sum / count;

// Iterate the loop for calculate distance

for (int i = 0; i < count; i++) {

//Display statement

System.out.printIn(" Distance from " + values[i])

+ " and average :"+ Math.abs(average - values[i])+ " is "

+ average) ;

}

}

}

}

THE ERROR I AM GETTING IS......

DistanceFromAverage.java:39: error: not a statement
+ average) ;
^
DistanceFromAverage.java:39: error: ';' expected
+ average) ;
^
2 errors
Error: Could not find or load main class DistanceFromAverage

1.CODE->

import java.util.Scanner;
public class DistanceFromAverage {

public static void main(String[] args) {
// declaration of values as double type
double[] values = new double [20];
int count = 0;
double sum = 0;
double average;
//Declaration of scanner object
Scanner input = new Scanner(System.in);
// Get values from user and iterate the loop up to 20 numbers
for (int i = 0; i < 20; i++) {
//Display statement
System.out.print("Enter the value(99999 to exit):");
double number = input.nextDouble();
// it breaks when values is 99999
if (number == 99999) {
break;
} else {
count++;
values[i] = number;
sum += values[i];
}
}
//checks whether count is zero or not
if (count == 0)
//Display statement for an error message
System.out.println("Error! Please enter any values");
else {
//calculation of average
average = sum / count;

// Iterate the loop for calculate distance
for (int i = 0; i < count; i++) {
//Display statement
System.out.println(" Distance between " + values[i]
+ " and average "+average+ " is : "
+ Math.abs(average - values[i])) ;
}
}
}
}

2.OUTPUT->

   3.EXPLANATIONS->

(1) In line 31 and 39, you are using capital 'L' in System.out.println() but it is not capital 'i' but small 'L',

[ 'l' for lion ], for better understanding , just change it.

   (2) In line 39, you are using an extra closing parenthesis ')' in System.out.printIn(" Distance from " + values[i] ' ) '

   The indicated ')' is redundant in your code.

  

   Rest of the things are working fine. You can see the corrected version of your code above and also see the    attached output.

After doing above two suggested changes your code will work fine.

Apart from that , the only thing i changed is printing order such that your output seems more consistent..

   It depends on you how you want to print it.

I HOPE YOU WILL GET IT..................YOUR RESPONSE WILL BE HIGHLY APPRECIATED
