Consider the classes below: public class TestA
{
Public static void main( String args[] )
{
Int x = 2,y = 20,counter = 0;
For ( int j = y % x;j < 100;j += ( y / x ) )
Counter++;
} // end main
} // end class TestA
Public class TestB
{
Public static void main(String args[])
{
Int counter = 0;
For ( int j = 10;j > 0;--j )
++counter;
} // end main
} // end class TestB
Which of the following statements is true?

Question

Consider the classes below: public class TestA
{
Public static void main( String args[] )
{
Int x = 2,y = 20,counter = 0;
For ( int j = y % x;j < 100;j += ( y / x ))
Counter++;
} // end main
} // end class TestA
Public class TestB
{
Public static void main(String args[])
{
Int counter = 0;
For ( int j = 10;j > 0;--j )
++counter;
} // end main
} // end class TestB
Which of the following statements is true?
A)The value of counter will be different at the end of each for loop for each class.
B)The value of j will be the same for each loop for all iterations
C)Both (a)and (b)are true.
D)Neither (a)nor (b)is true.

For TestA class, the value of counter will depend on the number of iterations the for loop runs, which might be different for different inputs of x and y. The value of j will start at y % x and increment by y / x in each iteration.

For TestB class, the value of counter will always be 10, as the for loop will iterate 10 times. The value of j will start at 10 and decrement by 1 in each iteration.

Therefore, the statement A is false and the statement B is also false. The correct choice is D, which is neither (a)nor (b) is true.
