Given the variables

String stars = "*****";
String stripes = "=====";
what do these loops print?
a. int i = 0;
while (i < 5)
{
System.out.println(stars.substring(0, i));
i++;
}
b. int i = 0;
while (i < 5)
{
System.out.print(stars.substring(0, i));

System.out.println(stripes.substring(i, 5));
i++;
}
c. int i = 0;
while (i < 10)
{
if (i % 2 == 0) { System.out.println(stars); }
else { System.out.println(stripes); }
}
