Consider the following class:
public class TestSample
private ArrayList samples;
public TestSample(int n)
for (int k = 0; k < n; k++)
samples.add(k);
public double getBestRatio()
double maxRatio = samples.get(1).intValue() / samples.get(0).intValue();
for (int k = 1; k < samples.size() - 1; k++)
double ratio = samples.get(k+1).intValue() / samples.get(k).intValue();
if (ratio > maxRatio)
maxRatio = ratio;
return maxRatio;
What is the result of the following code segment?
TestSample t = new TestSample(1);
System.out.println(t.getBestRatio());
A. NullPointerException
B. ArithmeticException
C. IndexOutOfBoundsException
D. ClassCastException
E. Infinity
