Consider the following class declaration.
public class Sample
{
private int a;
private double b;
public Sample (int x, double y)
{
}
a = x;
b = yi
}
// No other constructors
The following method appears in a class other than Sample.
public static void test()
{
Sample object =
new /* missing constructor call */ ;
}
APC
Which of the following could be used to replace /* missing constructor call */ so that the method will
compile without error?
