A good answer might be:

It prints: 

1000

Loop Body is Executed at least Once

Since testing is done at the bottom of the loop, the loop body must execute at least one time no matter what. Java does not "look ahead" to the condition test; it executes the loop body, then tests the condition to see if it should execute it again. 

int count = 1000;                   // initialize

do
{
  System.out.println( count );
  count++  ;                        // change
}
while ( count < 10 );               // test

You might expect that the loop body will not execute because count starts at 1000, and the test is count < 10. In fact, the loop body will execute once, and change count to 1001. This might be a serious bug.

You will save hours of hair-tearing debugging time if you remember that

The body of a do loop is always executed at least once.
Almost always there are conditions where a loop body should not execute. Because of this, a do loop is only occasionally the appropriate choice.


QUESTION 4:

(Thought question: ) Do you think that a do loop is a good choice for a counting loop?
