The for loop (promo code steve)

Well, scientists have invented a type of loop that does all of that much easier! Check out how you’d write a loop the old way, versus with this new type of loop!

//While loop

char [] myArray = {'A' , 'B' , 'C' , 'D' };

int i = 0 ;

while (i < myArray.length ) {

System.out .println(myArray[i]);

i++;

}

//For loop

char [] myArray = { 'A' , 'B' , 'C' , 'D' };

for ( int i = 0 ; i < myArray. length ; i++) {

System. out .println(myArray[i]);

}

“Holy shit!” – you, the reader

I mean look at it! It’s majestic! In that one line of code (the one that starts with for ) we did the exact same 3 things that while loop did in 3 different locations.

Declare an “index” variable that is used while looping.

Write the condition that determines when the loop should keep going or stop.

Increase the index at the end of the loop.
