Explanation / Answer

32)

value = 24
value = 20
value = 16
value = 12
value = 8
value = 4
------------

Reason:

for (int value = n; value > 0; value = value - 1)

This for loop will continue to execute until the value of the variable is greater than zero.

                                    if (value % 4 == 0)    

checking whether the number when divided with 4 the remainder is zero or not.

The if statement will be execute only for the multiples of 4

The value inside the variable value is 25.which when divided by 4 the remainder is not zero

So value=value-1=24

Which when divided by 4 the remainder is zero.

Then the System.out.println("value = " + value); will be executed which displays

Value=24

In the same way 23,22,21 when divided by 4 the remainder is not zero.

Next is 20

Which when divided by 4 the remainder is zero.

Then the System.out.println("value = " + value); will be executed which displays

Value=20

In the same way 19,18,17 when divided by 4 the remainder is not zero.

Next is 16

Which when divided by 4 the remainder is zero.

Then the System.out.println("value = " + value); will be executed which displays

Value=16

In the same way 15,14,13 when divided by 4 the remainder is not zero.

Next is 12

Which when divided by 4 the remainder is zero.

Then the System.out.println("value = " + value); will be executed which displays

Value=12

In the same way it displays

Value=8

Value=4

Next the value 3,2,1 Which when divided by 4 the remainder is not zero.

As the value of the variable is 0 then the control will come out of the loop.

Then the control will goes to the main method

Then the statement will be executed System.out.println("------------");

output:

I am WaitingHello Google; What is My Name?

_____________________

Reason:

As 7%10=7

then case 7 will be executed .So it prints "I"

Now the value of couter incremented by 1.So it becomes 8

As 8%10=8

then case 8 will be executed .So it prints "am "

Now the value of couter incremented by 1.So it becomes 9

In this way it printed up to case 10.

later the value of counter will become 10

As 10%10=0

Then case 0 will be executed so the statement System.out.print("Hello "); will be executed

then counter will become 11

11%10= 1

Case 1 will be executed.

In this way the cases upto case 6 will be executed.
