for ( int j = 0; j < 5; j++)
{

two[j] = 2 * one[j] - 1;
two[j + 5] = one[4 - j] + two [j];

}

System.out.print("Two contains: ");
for ( int j = 0; j < 10; j++)

26. What is the output of the following Java code?
final double PI = 3.14159;
double [] cylinderRadii = {3.5, 7.2, 10.5, 9.8, 6.5};
double [] cylinderHeights = {10.7, 6.5, 12.0, 10.5, 8.0};
double [] cylinderVolumes = new double [5];

for ( int i = 0; i < 5; i++)
cylinderVolumes[i] = 2 * PI * cylinderRadii[i]
* cylinderHeights[i];

for ( int i = 0; i < 5; i++)
System.out.printf("%d %.2f %.2f %.2f %n",
(i + 1), cylinderRadii[i], cylinderHeights[i],
cylinderVolumes[i]);
27. When an array is passed as an actual parameter to a method, what is actually
being passed?

Suppose you have the following class:
public class NamesList
{

28.

private String[] namesList;

//Constructor with a variable length
//formal parameter
public NamesList(String ... names)
{

namesList = names;

}

//Method to return namesList as a string
public String toString()
{

String str = "";
for (String name : namesList)
str = str + name + "\n";

return str;

}

}
