While loop is not very clear

int i = 0;
int j = 10;

while ( i < j )
{
    println("Hello there");
    i++;
}

println("While is done, goodbye");

It like this:

-On line 1 we declare integer variable i with value = 0 -Line 2 we declare integer variable j with value = 9 -Line 4: you start the while loop: -the while loop first checks if the test is TRUE meaning that i=0 and it is smaller that j=10 so this test is true and it runs the command in the while body

• it prints out the string and increments the i variable by 1 ( i++ is the same as i= i+1;)
• now it reaches the end of the body and goes back again to the while line and tests again if the statement is true
• when i = 10 the while test comes back FALSE because 10 is not smaller than 10 but the same so the loop stops and the programs continues on the last line which prints that the loops is done.

Hope this helped....

Got it. Thank you very much for a very clear explanation!!
