Modify the Student class getAverage() method to drop the lowest grade when calculating the average. You will need to loop through the array and find the lowest grade.

Question

What will be an ideal response?

Answer 1

```
/**
* Method to r e turn the av erage of the g rade s a f t e r you drop
* the l owe s t grade f o r t h i s s tud ent
* @return the ave rage o f the g rade s or 0.0 i f no grade ar ray or
* no g rade s
*/
public double getAverageDropLowest ( )
{
double average = 0 . 0 ;
double lowe s t = 100;
int numGrades = this . gradeArray . l eng th ;
i f ( this . gradeArray != nul l && numGrades > 0)
{
double sum = 0 . 0 ;
// loop through the g rade s
for ( int i = 0 ; i < this . gradeArray . l eng th ; i++)
{
// check i f t h i s i s lower
i f ( this . gradeArray [ i ] < lowe s t )
{
lowe s t = this . gradeArray [ i ] ;
}
// add t h i s grade to the sum
sum = sum + this . gradeArray [ i ] ;
}
// i f t h e r e was more than one grade remove the l owe s t
i f ( numGrades > 1)
{
sum = sum ¡ lowe s t ;
numGrades¡¡;
}
ave rage = sum / numGrades ;
}
return average ;
}
