[Leaky]

here's a more proper write up about the different loops.




For loop:
the for loop is used to execute code so long as the iteration condition is true, i.e. i < 10


infinite for loop has no condition.:

Code:

for(;;) { }

the structure of a for loop

Code:

for(counter initialization; condition; counter change) { code }

you can have multiple variables aswel

Code:

for(int i = 0, int k = 100; i <= 50 && k >= 50; i++, k--) { }

while loop:
a while loop doesn't have a counter variable, it executes so long as the condition is true.

Code:

while(condition) { code }

a while loop executes the condition first and tests then executes code.


do-while loop:
this is the same as a while loop except code execution happens first, then condition execution.

Code:

do {
code will always execute atleast once
} while (condition)

other than that the do-while and while are the same


for-each is used for iterating through an iteratable collection.

Code:

foreach(holderVariable in iterableObject) { code }

as it iterates through the collection the holder variable is filled with whatever is in the current location in the collection and can be used as a direct reference to the object (not a copy) so changing the holder changes the object in the collection.






the important thing to remember when using loops is to always have a way out, infinite loops are not your friend. in a for loop make sure your condition will eventually return false. in your while/do-while loop make sure your condition can either return false or your code has a breakout somewhere.
