| Explanation of answer is wrong in first iteration of the loop. i value is 1 and j value is 9 and so forth loop will be go on till the time loop's condition don't generate false. so value of in each loop will be: i=1, j=9; i=2, j=8; i=3, j=7; i=4, j=6; i=5, j=6; // j's value don't change because the at this point when i is equal to 5 will return false value which breaks the loop. Answer is correct but given explanation is wrong. |

| Please explain properly if i=1 & j=9 then how to 1 is greater then 9? | |

| Hi @Pooja, Initial value of I and j is 1, 10. 1 > 10 it's an false expression within the brackets followed by "if". So 'if' statement is not going to execute. After that the statement 'j--' is going to execute. Then 'j' is going to take the value 9. After that final while loop going to execute. Here '++i' is within the brackets, so I is going to take the value 2. But "2 < 5" so the Expression within the while loop brackets is true. So the code going to run again same like this which I explained initially. Like this the code going to run again and again until the Boolean expression in while loop is to be false. At a time 'i' will get the value of 5 and 'j' will get the value of 6. On that time 'i > 5' this expression going to be a false expression. Then the code will going to stop the run. So final answer is 'i = 5 and j = 6'. |

| Here i is pre increment, So, After executing this statement. while (++i < 5); i should be incremented by 1 first than it should be used in following SOP statement: System.out.println ("i = " + i + " and j = " + j); So according to me at after first loop, o/p should be like this: i j. -----. 2 10 (as j is post increment: first decrement, than use). |

| while(++i<5), how the value will be i=5. | |
