java - Add value to arrayList in android -
I am trying to add the difference value in the array list
ArrayList & lt; Integer & gt; arraylistPage1; {Int x = 0; for int j = 1; j and lt; = total page; j ++); (Int i = 1; i & lt; = rangeMode; i ++) {if (binary table [i] [j] == 1) {cardInPage [j] [x] = i; System.out.println ("Card Number:" + i); ArraylistPage1.add (i); Println (arraylistPage1); X ++; }} System.out.println ("Page -" + + "Total Card:" + + x); TotalCardInPage [J] = X; } But when I run it, the program stops.
Does anyone know how to fix this?
Thanks
Change the code to
ArrayList & lt; Integer & gt; arraylistPage1; {Int x = 0; for int j = 1; j and lt; = total page; j ++); Array list page 1 = new arreelist & lt; Integer & gt; (Border mode); (Int i = 1; i & lt; = rangeMode; i ++) {if (binary table [i] [j] == 1) {cardInPage [j] [x] = i; System.out.println ("Card Number:" + i); ArraylistPage1.add (i); Println (arraylistPage1); X ++; }} System.out.println ("Page -" + + "Total Card:" + + x); TotalCardInPage [J] = X; }
