    The output is 1.

    Explanation:

    int x = 1;

    do{

    System. out. print (x + " ");

    x--;

    }while (x > 0);

    System. out. println ();

    The statement above is an example of a do-while loop which is always executed at least once.

    In the above code snippet:

    1 is assigned to x in the first line. Then the do keyword start the loop block. Inside the loop block, the value of x is output which is one (1). Then, the value of x is decreased by one, making x = 0. Then, the while keyword is reached where the condition is tested. The condition check whether x > 0 i. e whether 0 > 0. Off course, the condition is false and the loop is exited.

    The last statement print a single line to the screen.
