What is wrong with each of the following code segments?

a) ArrayList values = new ArrayList();

b) ArrayList values = new ArrayList();

c) ArrayList values = new ArrayList;

d) ArrayList values = new ArrayList();

for (int i = 1; i <= 10; i++)

{

values.set(i - 1, i * i);

}

e) ArrayList values;

for (int i = 1; i <= 10; i++)

{

values.add(i * i);

}
