I made three corrections.
-------------------------------------------
import javax.swing.JOptionPane;
public class Calculate2 {
public static void main(String[] args) {
String firstNumber; // first string entered by user
String secondNumber; // second number entered by user
String thirdNumber; // third number entered by user
int number1; // first number
int number2; // second number
int number3; // third number
int average; // average of the numbers
int largest; // largest number
int product; // product of the numbers
int smallest; // smallest number
int sum; // sum of the numbers
// read in first number from user as a string
firstNumber = JOptionPane.showInputDialog( "Enter first integer" );
// read in second number from user as a string
secondNumber = JOptionPane.showInputDialog( "Enter second integer" );
// read in third number from user as a string
thirdNumber = JOptionPane.showInputDialog( "Enter third integer" );
// convert numbers from type String to type int
number1 = Integer.parseInt( firstNumber );
number2 = Integer.parseInt( secondNumber );
number3 = Integer.parseInt( thirdNumber );
// initialize largest and smallest
largest = number1;
smallest = number2;
// determine smallest and largest
if (number1 > number2)
result = "The largest is " + number1;
else if ( number2 < number1)
result = "The smallest is " + number2;
// perform calculations
sum = number1 + number2 + number3;
product = number1 * number2 * number3;
average = ( number1 + number2 + number3 ) / 3;
// create result string
String result;
if ( sum
== number1 + number2 + number3)
result = "The sum is + sum" ;
if ( product
== number1 * number2 * number3)
result = "The product is + product";
if ( average
== (number1 + number2 + number3) / 3)
result = "The average is + average";
// display results
JOptionPane.showMessageDialog( null, result, "Calculation Results", "The largest is " + largest +
"\nThe smallest is " + smallest + "\nThe sum is " + sum + "\nThe product is " + product +
"\nThe average is " + average, "Results", JOptionPane.PLAIN_MESSAGE );
}
}
-------------------------------------------------
The error that i'm getting now is as follows:
Calculate2.java:43: cannot find symbol
symbol : variable result
location: class Calculate2
result = "The largest is " + number1;
^
Calculate2.java:45: cannot find symbol
symbol : variable result
location: class Calculate2
result = "The smallest is " + number2;
^
Calculate2.java:63: cannot find symbol
symbol : method showMessageDialog(<nulltype>,java.lang.String,java.lang.String,java.lang.String,java.lang.String,int)
location: class javax.swing.JOptionPane
JOptionPane.showMessageDialog( null, result, "Calculation Results", "The largest is " + largest +
^
3 errors
I know it's something rather simple, but i'm stuck on this one.
