coupling

Source: John Meyer's questions

class test
{
int main=10;
public static void main ( String... blah )
{
coupler c = new coupler();
c.setMain( c.getMain() ); // 1
}
int getMain()
{ return main; }
}
 
class coupler
{
int pain;
void setMain(int mane)
{
pain = mane;
}
 
int getMain()
{  return new test().main;  } // 2
}
 

a.Replace line 1 with main = c.getMain();
b.Replace line 1 with a call to coupler�s setMain method with the argument - main.
c.Replace line 2 with return pain; and make no other changes to the program.
d.No changes are required.
e.None of the above.


The answer given b. I feel both b and c are correct.

Thinking about it, may be not. Pain will not necessarily have the required main value all the time.
Anyway, what's the purpose of this code?

The answer b is incorrect, as it gives error "you cannot make static reference to the non static feild main".
I guess the answer is there is no problem with code (though it is not printing anything).
