Question

**MEDAL + FAN**
Please check my Java Programming answers.

If I answered a question incorrectly, please show me how to get the correct answer (it's fine if you don't, however). I'd like to learn how to do it on my own.

Answer 1

The term associated with loops inside of loops, is called a nested loop. You can have a nested for loop, nested while loop, nested do-while loop ect.

Answer 2

For question no. 3: the question is: there is a nested for loop inside a for loop- the outside for loop has 4 iterations (iteration means to cycle- so the outside loop cycles through 4 times.) and the nested for loop has 3 iterations --How many times does the Initializer run in the nested for loop:

So, I'll start with the syntax of a for loop-
for(<initializer>; <boolean>; <update-expression>) {

}

In a normal non-nested for-loop, the initializer will initialize once total, and it does so first before anything else.

but if you had a for loop in a for loop- the initializer in the inner for loop will execute as many times as the outer for loop executes. For Example:

int accumulator = 0;
for(int count = 1; count <= 10; count++) {
System.out.println("After the program runs, this message will show 10 times");
for(int innerLoop = 1; innerLoop <= 5; innerLoop++) {
accumulator = accumulator + 1;
}
}
System.out.println("This program has a total of " + accumulator +
" iterations.");


This is an example of a nested for loop- the inner loop will initialize variable innerLoop to equal 1, then run through 5 iterations before finishing, then the outer for loop will run again. This 2nd time through, the initializer for the inner loop will initialize again- setting innerLoop back to 1, so it can cycle through another 5 iterations.

I'm assuming you have some knowledge of for loops already.. if you don't understand something- let me know.

Also, a trick for finding out the total number of iterations in a nested for loop, is to multiply the number of iterations of each loop. So if an outer loop has 10 iterations, and the inner loop has 5 iterations-- total number of iterations = 10 * 5
