Working with computers, you quickly learn that they lack any sort of insight to solve problems on their own.
On the other hand, the computer is happy to execute the code we specify a million times over, which is its own sort of power.
Loops are the way to do this.
A while loop has a boolean test and a body containing statements, like this: The while-loop extends this idea, executing the body again and again, checking the test each time.
The while-loop follows these steps: Check if the test is true or false. If false, the loop "exits" and does not execute the body. If the test is true, continue with step 2. Execute the body statements, starting at the top and proceeding down through them all.
Go back to step 1 and check the test again.
If it is true, run the body again. Each time the body finishes, "loop around" and check the test again. Each run of the body is called an "iteration" of the loop. Eventually the test is false, the loop exits, and the program continues with the line after the while-loop.
For example, the above while-loop prints: The count variable starts at 0, and increases by 1 on each iteration. On the th iteration of the loop body, the body prints "99" and then increases count to On all previous checks, the test was true. This time the test is false, and the loop exits without executing the body.
We use while-loops to execute some code until some condition is satisfied. Or put another way, the test is the "green light" condition that says that each iteration can go ahead.Java: Create method to print all multiples of 3 between 1 and n?
