Hello

I am taking a shot in the dark here.

Could anyone explain in simple terms how a nested for Loop works please?

I have just got used to working with single looping structures and I have been introduced to nested loops and I just cannot seem to get my head around them.

Thanks

Kevin - we've covered this one before I am pretty sure. What difficulties have you run into now?

In 'short' - a loop completes whatever task you set it, up to its iteration limit. If it is enclosed by another loop, - (nesting) - that outer loop takes another iteration, and the inner loop is repeated.

class Loop{

public static void loop(){
	for (int a=0;a<10;a++){
       	    System.out.println("Out loop value is --->"+a);
       		for (int b=0;b<20;b++){
             			System.out.println("Inner loop value is ---> "+b );
       		 }
	}
}

public static void main(String[] args){loop();}

}

*Did* you mean nested, then? If so, there's a short and v simple one above. Let us know if this is not what you had in mind. There is plenty of help here if it isn't.

And you didn't knock a single point off because I names the outer loop 'out' instead of 'outer' ! ;)
