Writing Methods--Repaired Example

public char letterGrade (int iGrade)

{

char chReturnValue = ‘I’;

util.ASSERT(iGrade >= 0 && iGrade <=100,

“iGrade param has invalid value.”);

if (iGrade >= 90)

chReturnValue = ‘A’;

else if (iGrade >= 80 && iGrade < 90)

chReturnValue = ‘B’;

else if (iGrade >= 70 && iGrade < 80)

chReturnValue = ‘C’;

else if (iGrade >= 60 && iGrade < 70)

chReturnValue = ‘D’;

else // given Assertion, iGrade must be < 60

chReturnValue = ‘F’;

return (chReturnValue);

} // of letterGrade

Is this right?
