Array declaration

String[] words = new String[10];
String[] words = { "yes", "no" };

values[2] = values[1];
values.set(2, values.get(1));

Use hasNextDouble

public HomeworkScores(int maxScores)
    {
        System.out.println("enter socre 0 to quit: ");

        while(userInput.hasNextDouble())
        {
          double nextScore = userInput.nextDouble();
          socres[currentSize] = nextScore;
          currentSize++;
        }
    }

public double sumScores()
    {
        double sum = 0;
        for (double score: scores)
        {
            sum = sum + score; 
        }
        return sum;
    }

output average score

public double averageScore()
    {
        if (currentSize == 0)
        {
          return 0;
        }
        else {
          sumScores() / currentSize;
        }
    }

remove lowest score

public void removeLowest()
{
      double low = LowScore();
      int lowScoreIndex = find(low);
      remove(lowScoreIndex);
}

public void getLowScoreIndex()
{
double lowestScore = scores[0];
int lowestScoreIndex = 0;
for (int i = 1; i < currentSize; i++) { if (scores[i] < lowestScore) { lowestScore = scores[i]; lowestScoreIndex = i; } } return lowestScoreIndex; } [/java]
