Join Peggy Fisher for an in-depth discussion in this video Comparing different types of loops, part of Learning Java.
- When testing the programs we've written so far…we had to build and run the programs each time…with different input values.…It is not hard when we only have a few test cases…but what happens when we wanna test one hundred values…or maybe even a thousand?…Or better yet maybe we don't even know…how many times the program needs to run.…Fortunately, we have several ways to repeat…a block of code.…Java has three types of loops:…a do while, which is a post test loop,…a while loop, which is a pre-test loop,…and a for loop, which is also a pre-test loop.…
Each loop has a specific purpose.…The do while loop executes the block of code…at least once since it doesn't check the status…of the condition until after executing the code in the loop.…A while loop repeats as long as…a conditional statement is true…and a for loop executes a predetermined number of times.…Let's review the syntax for each of the loops included here.…I already have a program opened called Loops.…And I've created three loops.…Each loop does exactly the same thing.…
