Thread: what wrong , please

import java.util.Scanner;

public class TestScoresAndGrade {

public static void main( String [] args ) {


Scanner scanner = new Scanner( System.in );
double score1;
double score2;
double score3;

System.out.println( "Please enter the first score" );
score1 = scanner.nextDouble();

System.out.println( "Please enter the second score " );
score2 = scanner.nextDouble();


System.out.println( "Please enter the third score " );
score3 = scanner.nextDouble();

average = ( score1 + score2 + score3 ) / 3;

if( average < 60 ) {

System.out.printf( "The average score is: %f. Thats a grade F", average );

} else if ( average < 70 ){

System.out.printf( " The average score is: %f. Thats a grade D ", average );

} else if ( average < 80 ){

System.out.printf( " The average score is: %f. Thats a grade C ", average );

} else if ( average < 90 ){

System.out.printf( " The average score is: %f. Thats a grade B", average );


} else if ( average <= 100 ){

System.out.printf( "The average score is: %f. Thats a grade A", average );


} else {

System.out.println( "The average score is"+ average +". Thats a invalid average" );


}

}


}

I'm imagining its something like:

error: cannot find symbol
    average = ( score1 + score2 + score3 ) / 3;
    ^
symbol:   variable average
  location: class TestScoresAndGrade

But thats just a guess. If so I can't find where you defined average.
