What is the purpose of a do-while loop?

Question

I know what do does, and how it cooperates with the while loop, but won\'t a while loop code be the same, whether or not the do is there?

Answer 1

if you write the "loop" like so (without the do as in your question):

int i=0;
{
    System.out.println(i++);
}while(i<10);

it will just print out 0 (nothing more), and not loop 10 times.. so no, the loop won't be the same if the do isnt there.
