What is the output of the following Java code? int x = 1; do{System. out. print (x + " "); x--; }while (x > 0); System. out. println ();

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.
