Suppose we have a method in class Thing which has header:
public void modify () throws ModifyException
Suppose t refers to an object of type Thing, and count is a variable of type int. Which of the following would have the effect of setting count
to the number of times the method modify () can be called on the object that t refers to before a call of modify () on t causes a
ModifyException to be thrown?
Select one:
O a.
count=0;
for (;;)
try {
t.modify () ;
count++;
}
catch (ModifyException e) {}
O b. count=0;
try {
for (;;)
{
t.modify ();
count++;
}
}
catch (ModifyException e) {}
O c. count=0;
for (;;)
try {
t.modify () ;
count++;
break;
}
catch (ModifyException e) {}
O d.
count=0;
ry {
for (;;)
{
count++;
}
}
catch (ModifyException e)
{
t.modify ();
}
